Great pictures.  I have rabbits and guinea pigs and it seems like it is a lot easier to sex the guinea pigs than the rabbits.  I have a pregnant female pig, who when she has her babies, I can sex them easily with the pictures.

Thanks for these pictures, they've confirmed my sons guinea pig, who we thought was a he, is a she and is prob pregnant as she is getting fatter by the day.

Thank you soooo much for posting this!! I am sitting a little GP for my sister's birthday. Now i can tell her she has a little boy.
Thanks again!!!!!

Thanks so much for the info!  I am "babysitting" a GP this weekend, and had no clue about their behavior or nutrition!

awesome info with great pics! very helpful!! thanks eversomuch!

This is a good thing - my guinea pig had 4 babies last night and I wouldn't have a clue how to sex them so this is just fab. Nothing odd or sick about not wanting any more pregnancies. Thanks for the help....

"Somewhere in Alabama", please realize that if you have animals, sometimes there is going to be some unpleasant stuff that has to be done. Finding out the sex of your animals is not always easy, and these pictures help. You're the one labeling it as "nasty" and "sick". A responsible owner needs to know, to ensure males and females are kept separate.
You must be young. This stuff is mild compared to jobs that must be done on ranches and farms.

I thought both of my GP's were female - until last night when I realised one of them is heavily pregnant! The male one does not have any protrudence like your photos, they both look exactly the same on the outside, but you can feel testicles on one of them.. they are around 5 months old. So make sure if they LOOK female - feel just under the genitals for anything resembling testicles. I'm in shock!

Great pictures and easy to follow instructions. I was able to sex my 2 week old gps. Thankyou

this is a great site!  I have one guinea pig we adopted from a pet store where they told me it was a male.  We recently got two females, but live in a very small town with no small animal vets.  Your site helped me to determine the sex of all 3 pigs, and I am pretty sure they are all females, but I am still worried about putting them together because I really don't want any unwanted babies.  What is the best way to introduce them to each other and how do I determine if they really are all females?

Wow, great pictures...what a relief I thought I was given a boy and a girl when I asked for two girls,but you really cleared up any doubt Thank you so much great job, i had read about it but so much easier this way, keep up the great info.

Thanks so much the pictures are so clear i was able to tell what my baby guineas were straight away!!!

Thank you so much for your informative and VERY helpful website. The pictures are very clear and precise making it much easier to tell :) I went to 3 websites but ended up using yours to make the call on the sex of our babies.

this was really helpful, because, like you said, sometimes there are mistakes!  Thank you soooo much!

hi, thanks.Its Great u have uploaded photos to determine sex of pigs. My pet seller gave me wrong male instead of female.
Its actually hard to determine sex just reading text.

thanks Great work !

Thank you so much for the excellent descriptions and photos...it  was a breeze to correctly ID my rescue as an intact male...no one at the pet store could tell me. I will def forward this site to all that need some help!

Thanks so much for these pics they were a tremendous help. We had one male gp and rescued two more thanks for help preventing the males from fighting. Oh yeah and babies we really didn't want lol.

This info helped me out a lot in picking a GP!

Thank you, very good web site I thought I had 3 females and one male but couldn't find any pictures at 3 weeks of age to confirm this until I looked here.

good site. i think i can feel the shaft above the genitals and i introduced 2 females and my pigs started fighting so i think they're males. ;)

thnx for the tips. the shop told me my guinea pig was a male. they were so wrong.

This was very helpful! Thank you so much, now I know I have to girls to take care of. :)

HELP.  Although you have many great photos on your website... I still can not tell what sex our babies are.  Since all three of our babies have exactly the same genitals... I know there are either 3 girls or 3 boys.  I don't feel any shaft, and I can't get anything to "come out".  But I am still not convinced they are girls.  The mound at the top of the y is kind of pointy.. maybe the penis is 'hiding' within that point?  These babies are 2 weeks old...and I know that you need to separate boys from girls at 3 weeks old.  I keep checking EVERYDAY...
Advice please!
Cynthia

geeszz!! i can't identify in my pigs who's the male & the female. I receive them as a gift last christmas. i think they're 2 months. Can you heLp me guys?? xoxo

Sabrina,, your guniea pig is a girl it is mounting the others because it is in season

We got our pig from the pet store 2 months ago and today, we came home to babies! We will be using this information over the coming weeks to sex them - great info, the pictures should come in quite handy...

i love my babys and thank u for the info.

I am having a really hard time figuring out my piggies. I have two and niether one looks like a male, but the younger one will not stop mounting the other. What is going on?

I bought a new g-pig on the weekend from a pet store, I tried to sex it myself and I couldn't get anything(penis) to stick out, so I thought it was a girl.  I asked one of the workers to sex it and she said it was a girl.  Today I tried to sex it and got what looks like a penis to stick out...... hummmm.... I guess I gotta change it's name now!

Thanks for all the photos, great article.

I tired checking my babies today and I didnt really suceed at anything other than getting a few scrathes. guess i will try again at 3 weeks old! the website is a great help though i look here everyday for information that could be useful!

Wow. Now I know that my cavy is, in fact, a girl. Thanks! I was worried when you said that you shouldn't trust what pet stores say they are...

Thought this tutorial was great!!! Thank heaps. Have saved me from having more guniea pig babies. Was able to seperate the babies from mummy before anything happened.. Thanks Heaps Again!!!

wow I didn't know that ^-^

Thanks for the photos, it all becomes very clear when you are shown the difference. 'It's A Boy!'

Thank you so much for these great pictures and information. We had three babies about a week ago.  Now I know what sex they are.

Those pictures are soooo gross. I wish there was a wand to find out. I hate it. yuk.

This is important information and worthy of all scientific detachment and you are to be commended for doing such a superior job.  However, I must say that in picture #22, pig 10 has the most adorable "Say WHAT?" look on his face.

ive just purchased 2 babies guineas about 5weeks-3months old and i was told they were female but 1 seems to have testicles but no penis :S is this just a little thing that will clear up?

OMG I've been calling my guinea pig Mu [Mufasa is "his" full name] thinking my little one was a boy for so long. I feel like a very bad parent... I shoulda named it a unisex name like Sam or something lol.

Looking at these pictures, I'm convinced my old guinea pig wasn't the boy he was supposed to be...

thank you soo much for putting those pics online
i was told by a vet that my little piggy was a boy but i was convinced that he was a she and since looking at you pics ive confirmed it

thanks soo much

thanx for the sexing info. good veriety of examples

I would like to say that not all pet stores are that bad. I got my beautiful cavy at my local PetSmart ( which has an in house vet) and an awsome small animal care giver named Nick. I know from specking with the store and dis. managers that all cavies sold from PetSmart stores are MALE. I couldnt be more happy with my new little boy. His name is SYDNEY. ( sid)

Thank you. Now I know that my little brownie is now a she instead of a he. She's getting along fine with my other g.p fine

Well wot can i say thxs to you we know have discovered our little goldie is no longer a girl like we thought but a boy lol.
so she is in with another boy and get along fine thankfully.
so your pics on sexing guinea pigs was a gr8 help to me and my 8yr old daughter.
thxs again

I am so happy about this guide! I was worried my pig might be a male since we got her from a pet shop. (A REALLY REALLY REALLY good petco) and I was worried she may have been a male. But she is definetly a female. Thanks Cavy Spirit!

Very good information. We are doing research prior to buying a 2nd g.p., and want to make sure of a smooth transition for both. Thanks.

hello,
my guinea pig isint even a year old and just had her litter.
shes ok but went throught a very difficult birthing experience.
i walked i the room and saw 2 babies in a corner then i say alota blood in the cage...one of the babies she birthed where just ribs with guts,it was really scary then i lifted her bed thing and saw her first born she hadent cleaned it,but thankfully 2 of the 4 lived and they are very cute.one is lightbrown and while and the other is black,darkbrown,lightbrown and white.i just wanted to tell you that your sight has helped me alot because this was the first litter that i have had and it woulda been hard without this info =)

thank you, your website was a big help. we are new guinea pig owners.

Hi, I bread from my guinea pig last October. She had a healthy brood of 3 female piggies. I have just watched her deliver again (I missed her in October). She had just 1 baby, I surprised as she looked so big. The baby is doing well and so is mum, very big baby though. I am just waiting for my other sow (the baby girl born in October) to deliver hers. I am unsure how far gone she is but I dont think it will be too long. I love this website and well dont to all the good work you put in. I would love to do something like you do, but I am so busy with a part time job, 4 childre, nusband, dog, parrot and 4 regular guinea pigs (not including any babies they produce). Thank you.

Hi, My female guinea pig got accidentally pregnant because one of my boys sneaked into her cage! It was so fast I was too late. She however fortunately had 3 healthy babies (1 died though). The 3 babies are now about 4-5 weeks old. I definately checked their genitals....and 2 of them are boys, 1 is a girl. But none of the boys are showing any mounting behaviour at all! Neither do they rumble at all. I have 10 guinea pigs and I love them so much. I have taken care of baby guinea pigs of my own before and the boys rumbled at 3 weeks so it was obvious they were boys. But this bunch...don't want to leave their mum and they don't want to stop having her milk. Another problem is...the mum won't let me take the babies away! She cries desperately for the babies back and even the (supposedly male) babies cry desperately for their mummy. But since I was so concerned for the mum, I took the boys away and the mum was so desperate she actually jumped out of the cage! and I was so concerned if I separate her from the babies, she will go looking for them at night.

I'm really worried. I don't know wwhat to do. My husband and I both checked the genitals so many times...we don't know what to do. PLease help.

We love your website and how caring you all are for taking care of unwanted Guinea pigs. We live in Australia and we would like to start a Guinea pig rescue here and also a website in the near future. It would be great if we could partner up with you some day.

Keep up the good work! =) I'm sure those adorable Piggies really appreciate it. Please reply to my question i'm so worried about my babies.

Thank you!

What a fantastic web site, sounds we are not alone when we purchased a  female, with hidden bundles inside !!  our little Dora was only 10wks old when we got her along with her 4 so called sisters !!  hmm that definatley wasnt the case either !! We were worried sick, as not knowing how far gone she was, it was down to day by day, we are so pleased to announce that she had 5 healthy babes, and they including mum are all doing well.

Thankyou so much you have made it so much easier for us to identify what sex are in the litter, and so far discovered 1 boy !! so now you have given such graphic pictures i feel so confident we can accuratley sex the rest.

Arn't they just the cutest little things at the best of times but the babies are even more adorable.

thankyou again

Laney & Damo

I'm replying to Julie's post from 5/25/08.
If you have a white pig who was born blind or deformed in any way, it is likely much more serious that appears on the surface. PLEASE read this thread about LETHALS: http://www.guineapigcages.com/forum/kitchen/4190-lethal-guinea-pigs.html

Thank you very much for your brilliant website. I am now the proud owner of 11 guinea pigs due to a multitide of pieces of poor advice from pet shops! Luckily I am pet mad so it is not a huge problem but I am keen not to expand my collection further so your website has been invaluable in sexing the new babies. One of the new batch was born with only one eye and is blind in the other. She is underweight as cannot follow Mum easily so we have been up every 2 hours to make sure she gets enough food. The whole family is praying that she pulls through. Even my gruff and tough husband has been giving her extra feeds and geting up in the night. Fingers crossed.

i have a guinea pig and jacks pets says it was a girl but my friend brought hers over and they were both supposed to be girls and mine started humping hers and so this website helped me figure out if my gunea ig was a boy or a girl. and it was a BOY!!!!!!!

I had purchased a rescued "baby" pig at a local ranch store, little did I know, she was pregnant. My young pig, Molly, gave birth on Mothers Day to 4 babies, one was a runt that died shortly after. The babies and mom are healthy and I thank you for this website! Very informative!

I rescued 2 baby piggies a week ago and this site has been most helpful to me in avoiding any unexpected litters.  Thankyou for your help.

We figured out both our guinea pigs are boys...one had nipples so we thought he was a girl but he is a boy...darn I'm disappointed no guinea pig babies for us

As we have just been blessed by an unexpected birth, you have been very helpful.  Thank You!

This was extremely helpful, thank you very much!

I am a Companian animal specialist for Petco and we would never miss sex a guinea pig. They must be 6-8 weeks old when they come to us. Be sure to mention "some" pet stores.  We always make sure the customer knows everything they need to know for a happy life for their new companion.

i love cavy's i hav three now and i adopted one from a little girl who was blind and could no longer take care of him his name is dezzy he is now 4 years old and he is extremely healthy. He is a roan. I also own a female who i adopted from a family that had 5 and had to find homes for them buy the end of the week. i was able to give 3 homes but they were so pourly cared for at old homes that they had to be put to sleep within a week of me owning them. One of the females that i got from themn was pregnant and i alaready new when i got her but i kept it a secret until she had 6 babies 2 days later. (my parents do not visit my room often. She gave birth to 3 males and 3 females. I found amazing homes for all but 1 who like to bite which i hav named rasberry. Her mother, teddy bear, is an abbysinian and rasberry is also an abbysinian. Now rasberry is 4 months old and pregnant with her first litter. Dezy is the father and after this litter he will be neutered. Rasbery si more than likely pregnant with more than 3 babies because it runs in her family. Her mother had either 5 6 or 7 babies in all of her litters (5 total) and rasberry is expected to hav more.

thanks! Im about to venture on a purchase for my grandaughter..I wanted to be sure and sex them..I think I can figure it out..Pet store told me too young to tell..WRONG..

This was very helpful. I am not going to let the petstore sex my piggies, i'm going to do it.

Thank you for your large display of photos a brought what i thought was two males 8 weeks ago from a pets store, ive recently come back from holiday two find a massive diffrence between them both. After looking at your pictures i took them to the vets to find one of them about 5/6 weeks pregant.

thanks so much... i thought that my guinea pig was a boy but then my friend had a book and it looked like a girls so im going to check but thanks...this helped me alot...

this helped me a lot with a school/4-h thing that i'm working on thanks

Thank you for posting these detailed pictures. Our momma just had 3 (got daddy neutered but the damage was done :( We have a home for 2 of the babies and will keep one. It all works out.

Thank you again for these wonderful images that others can use as a reference.

This site was a big help in determining the sex of my new pet. Thank you for the pictures that gave great detail and actually showed what you meant by the "Y" and "i" shape. Great Job!

i have two piggies one i know is boy but the other i cant tell they where in the same cage together she has large lumps on her back and small lump underneath please help

I see a few recent posts asking questions, so I thought it bore repeating that the page above requests:
"Please do not post questions in the guestbook, they are not answered."

my guinea pig is 6 week pregnant and tonight past a puss colurd fluid from her groin,please help.

how do you know if my guinea pig is a girl or boy

I need help.  New Owner.  Thought I had two females.  I was wrong.  What to do?

This is a very informational topic. Please send more!

i love kwowing more bout cavies

Thaks so much for grat deatailed info- now I feel more confident when I go home today and take a look at our three sweet babies.

Great Information- many thanks :) Guinea pigs are awesome.I have 8!!

we just love guinea pigs!we are adults and still find these amazing creatures loveable and priceless. the only fault with guinea pigs is their lives are too short and vets in australia(south australia) have no idea how to treat them. we treat our guinea pigs better than ourselves. we have them inside and enjoy every minute with them. they each have a personality of their own and we wouldn't live with out guinea pigs now. they are the best animals!

Thank you so much for the info.

I have 5 rescued piggies and someday will take more; always trying to learn what i can.

Thank you so much for all the advice you have put on this site. I have visited quite a few others and they don't even compare to this 1. I already had 2 female piggy's and have adopted 2 more baby girl piglets which nobody wanted (I don't know why as they are so cute!) I followed your instructions when I introduced them all and they are now like 1 big happy family! Now Tufty, cotton ball, rosie and coco (my daughter named them) are all living happily together. Once again thank you for all your help.

Thankyou for this site found it very usful!

Well, we are learning about the world of guinea pigs fast!  Your site is unbelievably helpful.  We were given a pig, cottonball 2 years ago, she is lovely, calm, stoic. We then gave in and took on two more guinea pigs that we were assured were both females as company for Cottonball, needless to say Miss Mo, is really Mr. Mo, and Miss Squeally had her first (and only) litter of two 8 weeks ago.  Bear and Caramel are very cute.  It was heart wrenching to seperate Bear at three weeks but we had to do it.  Today him and his dad hang out.  Cottonball is due with her litter any day now. (We didn't know Mr. Mo was a guy remember)  Today we put her in her new cage with all the bells and whistles awaiting  the joyous event. Miss Squeally and Caramel are in a cage beside.  We don't know if she has had a litter so I'm somewhat nervous about her delivery.  Having a family of vets at my beck and call definitely helps.  So.... I'm hoping that all goes well and this will be the end of pigs at our house.  We do adore them. (Daddy only tolerates them). The cats like to visit through the window, the gerbil and bird get a visit on occasion and the pug couldn't care less about anyone but herself!  Cheers, thank you for your invaluable advice.

Hello, Thank you for your information it was alot of help. I went to a different site before this one and it didn't explain as well as you did... I didn't know most of this and i have had my husband and I's pigs for almost 2 monthes now. My pig has started to get bigger she is possibley pregnant. I watch them everyday and play with them as much as possible. My dog baby She is a pug palm Not a big dog at all. This they are her puppies... She tried to play with them and cuddles with them. It is Very Cute.. Thank you again...!

I really appreciate the time and effort that went into this excellent site. I am a new piglet owner and I love them. I have four. I learned a great deal quickly, but I realize this was
only possible due to the experience garnered over much time by
many. I thank you all for sharing your knowledge. I will be a
solid parental unit, now, because of it !

Thanks for the info on this. Pet shop told me it was a boy but now I know my guinea is a girl. Was called Max so now I guess it is Maxine :)

Wow! What great pictures!! Thanks for all the info!

~Haley and Allie~

Hey... my guinea pig had babies not long ago :( Im finding it hard to sex the babies but thanks to your site im pretty confident that I have one male and one female :) theyre only 2 weeks so I will continue to make sure :) thankyou!

This was very good to know.  The pet store said it was a she, but it's really a he!  Good thing we named him Murphy it can be both a girls name and a boys name! lol!!  Thanks!

Just found this site, its great.  One of my sows gave birth 8 days ago and the other sow is due any day.  I now feel confident in sexing the piglets, thank you.

I wish I would have found this site a few months ago.  I bought 2 "males" from a pet store...they promised they had the males and females separated.  Needless to say I now have 3 new babies!  Very cute, but wasn't what I was looking for.

Wow, good to know.  Our 'he' that we got off of Craig's List is actually a she.  Very good to know!

This was really good! I know got it confermed, my girl isn't a girl, and 'she' made my other girl pregnant...!

This has great info! Thanks!

Thank you for the information, we found out that our "female" pig has a penis, good to know!

Thank you ever so much for the helpful advice on sexing guinea pigs and the clear photos, exactly what I need as someone called me yesterday for help. He has rather a lot of baby piggies as he has failed to separate the sexes early enough. I hadn't a clue as I am fairly experienced with rabbits but have never kept piggies. After studying your site I feel able to help this person.

good info

Thanks for a great website and pictures! I just received 2 adult pigs and 2 babies. I don't plan on raising any babies and had no idea what to look for.

Thankyou very much for the information, for the photos, they are very helpfull

I have never been able to tell if a guinea pig is a boy or a girl because my last guinea pigs we got from a frined. The pet store that we bought our now living guinea pigs from is working out better. I looked to see if I could tell if they were boys or girls and they were what the pet store said they were... girls. I knew that they were probably right because they are our friends, but I wanted to look for myself. Thanks for the pictures I recognised how to look for it when the pictures were displaying. I have been using your cage ideas and my guinea pigs are 100% happy with it.
    Thank you for the great cage,
Snippy and Olive

I don't know if any one can help or give me any guidence, but baically I had 2 guinea pigs one boy, one girl(ididnt know this till they had 3 babies. I separated them but the girl got pregnant again, so i had them proffessionally looked at and left the young male with mom and sister.  Unfortunatley the young male died in september but having JUST looked in the cage there are 2 more babies- is it possible they are from the one that died he was only about 4 and half weeks old???  If not I dont know whats happened.

This is such a nice site.

My guinea pig is a boy and im thinking of getting another boy and putting it in the same cage. Is this OK?

Help my too boys had babies, I'm keeping the 2 babies but i don't want this to happen again, the vet dose not know because he told me my boys were boys. one looks like a boar but the second one looks like smaller genitals of a boar; i'm looking to avoid another pregnancy. they are two weeks old any extra hints???

Help my too boys had babies, I'm keeping the 2 babies but i don't want this to happen again, the vet dose not know because he told me my boys were boys. one looks like a boy but the second one looks like smaller genitals of a boy. they are two weeks old any extra hints???

We got a guinea pig from the pet store and they told us it's a girl and we saw her pee outwards which i read means its a girl.. buuuut.. it looks like she has testicles.. poor Sprinkles has no identity.. does anybody have any hints to tell what sex he/she is?

very good

out of all the sites i have looked at in 2 days this one is the on that i have found very useful for having a guenie pig for 2 days thank you

This was the best site so far for helping me in purchasing my second guinea pig.  Thanks so much.  I couldn't help but wonder how much fun it was to snap all those pics, I don't know about you guys, but my guinea pig wiggles around non-stop if i tip her up!  Good Job!!

This page is brill, we love the clear photos and hope that they help to prevent unplanned pregnancies in cavies.
I have added a link from our forum, which can be found at www.devoted.to/guineapigs so that others may benefit.

Thank-you your site was very helpful at sexing my Guiniepigs.

Your site was perfect now I will be able to tell what sex my new little cavies are, so I know who to separate from the mom when the time comes thanks.

Your site was very infomative. I needed help because I am researching on breeding guinea pigs. I needed to know how to sex a guinea pig beacause I heard and read that it was hard to do at a young age.

Thank goodness for your information!  We have been doubting that our recently bought guinea pigs are both male as the mouning actions have been taking place more often than not!  We now have the information to be able to check and confirm their sex.  THANK YOU!

Very good site! Now i know that i have 2 males.Thanks

very helpful....great pictures!!!  You show a variety of photos!!!  Not all male look alike I have learned!!!  ;)!!!  Great site all my questions answered!

thanks so much.. we just got a guinea pig, we didn't know for certain if it was a boy or girl, this site helped alot

Brilliant web site, i have learned alot on sexing guinea-pigs Thank-you

Well well well... Got my Guniea Pigs from PetSmart.  Where they guarantee that all pets are female. One about 5 months before the other. The second pig apparently came into (and then when out of) the store pregnant. That issue has been resloved, (75% a new cage, bedding, food and toys for the new pigs) I still found your site to be more helpful in determining what else we needed to do. Thank you so much!

This is really the best web site about guinea pigs.I love this site.:)

Thank you so much for the info.  This website was really helpful, and I have learned more on how to identify the sex of the guinea pig at an earlier age.  I can't wait to see what my female will give birth too.  So that I can let others know what sex they are.  Again thank you for this information.
Nancy

what is the life expectancy of a male guinea pig?  Our guinea pig is a very much a part of our family.  His wanders the yard during the day with our dog and pet pot belly pig and is in with the family at night.  He is about four years old and I just discovered what feels like a fatty lump on his side.  Is this common in a guinea pig this age.  Thank you from a very concerned guinea pig family.  Lisa

i have two boy guinea pigs but they keep on fighting and it keeps on scearing me can you give me any tips on what to do and will they stop in a fuw weeks

i want a baby guinea pig that is about 5 weeks old

a very wonderful website your website truly magnificent ive learned so much. thank you to all youe informations. god bless yah. mwah.

a very useful website that can answer most of your question.... this site also gives a lot of info for new guinea pig handlers like me.... THANK YOU

very educating

Ok. I'll try this method at home but some of those pictures you still can't tell whether it's a boy or girl. I have a two preg piggies at home cause even my retarded vet got it wrong. Sexing is difficult. You think if I took pictures when the babies are born you could tell me??? I'm keeping all the babies and I've built an enormous cage for the bunch once they are born. I'm going to keep girls on the top floor and boys on the bottom floor but I've got to know their sexes before I seperate them! Wish me luck.

I think that this website should tell us how to sex the babies when they are under three weeks of age. I did not find this a very good sorce. It fricken sucked!

it was very helpful to me

You were very helpful in sexing my pigs!  Thanks!

VERY good photos, thanks for the help! I think I can do this now!

I'm still confused about finding the sex and don't want to hurt my piggy, so I'll still take him/her to the vet to find out, but thank you for this page.

yall make it look so ez but i have 3 new babys and it is kinda hard

Your photos make sexing very easy. Thank you

this was very helpful in making things clear!

its a awsome web site!! from number onre guinea pig fan

great help

i have 14 piggies 12 girls and 2 boys. we keep them apart so no more babies.we love them heaps

I have been reading about the felt for the bottom of the cage.  What kind of litter is best for their litter box?  I had a piggy years ago. Now our children share two.  We thought we had a male and female, but now I know we have two males.  They are only about 8 weeks old, and so sweet.

I have three guinea pigs one is a girl and two are boys. The Girl is in her first week of pregnancy she is getting big!

this is great info we are planning to sex our sows so these tips are really useful thanks

Thank you for the great info.

thank you for the info on sexing.  We have a new litter and some anxious guinea pig recipients that cant wait for their particular boy or girl!

Have had pigs for a long time, excellent site.

I just got a pig at the pet store, he seems like he's going to be a great family pet. Now he needs a friend!

i am getting a guinea pig tomorrow very excited as this will be a new breed for me there should be some lovely babies

just got a guinea pig today!!

I have had a guinea pig for about 1 month and decided to get another one today.  When I brought the second one home and put the 2 together, the first one started trying to mate with the second.  Is this normal as I am positive that both are male?

I have had a guimea pig for about 1 month and decided to get another one today.  When I brought the second one home and put the 2 together, the first one started trying to mate with the second.  Is this normal as I am positive that both are male?

im a novice and i want to have a pet guinea. how and what should i choose for my pet?

Now I have confirmed that my gps are boy and girlI have them almost 3 months already. What I want to know is at what age do they mate as I don't see them mating. Could it be my cage is too small. It's 3'x 2' big.

MY GUINEAPIG "SPEEDY" IS NAMED AS A BOY. BUT TODAY I SAW SOMETHING PINK UNDER WHERE HIS TOOSHY IS. IS THAT NORMAL? IS IT A GIRL CHARACTERISTIC? OR A BOY'S? IS IT NORMAL?

My friend was asking me to look up some information for her guinea pig and i said sure! she wanted to know how to tell if the guinea pig is a girl or boy so she can tell if they should be in the same tank! your site helped me thnx soo much for your time and reasearch pages!!!!

We thought we had bought 2 females however nearly 2 months later one was pregnant! This site is going to help us properly sex the pups when we seperate them and when we give them to new homes. We're keeping our fingers crossed that the mother and her pups survive!

We also thought we had a young female who turned out to be male, she was with 2 females aged just over 4yrs for 2 days before we found out!!!

i have a guinea pig who is a male and i thought it was a female but your site helped me confirm thaks alot!!!

I just took in a very pregnant female from a bad store, I also have 5 other abadoned and mistreated girls, your site is immensely helpful and I thank you for all the work you put into taking care of these wonderful animals! I refer back to here often. The sexing section will help me a lot with the babies as they grow so I can avoid my sweet momma Hope from ending up like this again (if all goes well of course keep your fingers crossed for her and me!!). THANK YOU SO VERY MUCH!!

YOUR SITE IS GREAT i HAVE NEVER SEEN A SITE WITH AS MUCH DETAIL AS YOUR THREE CHEERS!!! WELL DONE.

I just adopted two piggies from a petstore where they were dropped off.  Your site has been enormously helpful in posting the hazards of piggie pregnancy. Thanks!

We are adopting a piggie tomorrow from an animal shelter.  Although we know he is a male, this site is a valuable educational source.  We also learned a lot about the danger to females from breeding.  The key word here is Adopt, Adopt, Adopt.

Thank you. I am now sure I have 4 new babies. 3 males and a female. Thanks for the great info.

You've been to so much help... thanks a lot...

my gunieapig is pregnant there are 3 others that live with it we need to know whick other one ddid it

Thank you for your help!  Our youth center just "inherited" several guinea pigs and several are pregnant!  They are all going to good homes but we don't want more babies.  This is such a helpful sight!

this is a very helpful  web site thank you

this is good stuff to wether they are males or females

my guinea pig is pregnant and i needed to know how to tell the differences between boys and girls so i did not get the daughters pregnant with the father

This was very helpful and I passed it on to my daughter because she has several pigs and needs to know for sure which is which.

Learning material

Very helpful, I am going to double check right now!

Pics of great help. Can't wait to read the rest! Thanx.

Very helpful. Pics really help too. GREAT!

very helpful.  Thanks.

This was helpful.  The pics are great.  A little more play-by info would help too.

this is g8 as i can use it for sexing young guinea pigs!!!!!!!!!!!

These are the most clear and easy to use images I've encountered for "sexing" cavies.  Thaaaaaaaaaaank you!

thank you for the pictures they helped my alot

Oh boy these pictures helped alot...at some point I though one of my cavy's was a female, then I thought the other one was, but they're both boys!  THat's what I wanted ^_^;;  Hehe...

thanks for the pics. They helped alot. I bought a "male" quinea pig today, but going by the pics he's a she!

i have had guineas for years and thought i could easily sex them. i'm not all that good it seems and got really nervous about my frenchie's new pal valentino. i was afraid we were going to have to rename him valentine! thanks to your site i can sleep easier! and my piggie kids are doing great!

this site is great it helped me with problems with my guinea pig thanks!!!!!!!!!!!!!!

Thanks for the info.  My guinea pig had pups a couple of weeks ago and the information sure will help.

thack for this pic how to sex the guina pigs

My two sow's had babies 2 days apart. They are all six very cute. However they are very hard to determine a sex.  they are barely a week old, so I guess I need to wait another week to try and tell..

We had our first two sows deliver in the same week!  8 babies!  I'm totally confused sexing them althiugh your photos are very helpful.  The older litter is one week old and I still cannot tell them apart.  Hopefully by three weeks they will have the clear identifications I see in your photo journal.  Thanks for being so helpful!

I have classroom piggies, two of them!        They are still pretty young and the owner of the parents didn't know their sex.  Thanks for the "how to" manual.

My guineas had babies, great pictures now i've got a much better idea of what im looking for, if only I could get them to stay still. Thanks

Just got a piggie, pretty sure she's a girl(she seems pregnant). Got her at a pet store(well a relative did)

i just got  guinea pigs and thanks to your website im going to make sure if there either girls or boys. thanks!!!

iam finding it hard to sex my guinea pig ,i was hoping to get another one to keep it company. i have attached a picture can you tell me its sex? the pic is a bit blurry. thanks.

we love our guineas

you have no idea how gratefull i am to this site.i live in india where an exotics vet is almost unheard of,and so though we have very competent vets,most of them are ignorant about treating guinea pigs.which means the only exotics vet i have access to is this site.and it has never let me down yet.and i hope it never will even in the future.

thank you so much for this site. i was trying to sex my new pups (our first guinnea pig)and she was pregnant when we got her and i have NO idea how to tell them apart. the site was extremely helpful. thank you again and may God Bless You.

this is one of the most awesome, informative, fun and accurate websites on piggies I have seen!  I refer to it always.  The detail and the care and the humour are all awesome.  Thank you so much! When I had questions about introducing a new pig to our piggies the page on "Social Life" told me everything I needed to know, and I mean everything!  Thank you Thank you Thank you!!!!!!

I LOVE IT! MORE MORE

How do you know when your guinea pig is prednant.

I am so glad I found this site, I think the pet store sold me a male & a female pair, I wanted two females.  I need to check them again. Thanks for the pics, they will help in knowing what I am looking for.

I am really glad my boyfirend found this site.  The pet store gave me the wrong sexes on my quineas, I wanted a boy and a girl, I did get them, but they told me the wrong ones. For health reasons this was important.

at 1st this kind of thing freaked me out. but it's all about education that what i now understand. i really want to no about the little guineas because i'm soon getting one.

Could you please tell me how early I can tell the sex of my four baby guinea pigs?  They are 3 days old now....Thank you.

Very good work, nice webpage.

Thank you.  Very informative.  I used this information to determine the sex on my guinea pig.  Thank you again.  I have a boy.  Well, he is an adult boy.

thank you for the help on sexing pigs i own 6 of them one who is exspecting july17th 2005

Jessica, female cavies don't have periods. Instead, every 2 weeks, she comes into 'heat'. The only noticeable difference is that her genitals are slightly larger than normal, and she may try to mount other piggies more often (or other piggies try to mount her and sniff her bum more than usual).

Dofemale guinea ppigs have periods?

I was wondering if perhaps you could add pictures of a female in heat? I believe fairly strongly that I have two females, but I put them together and they tried to get it on.... I'm wondering if it's because one is in heat? She looks different and I'm not sure what that means.... thnxs

i loved the way you helped me out now i no alot abount guinea pigs thanks

Extremely helpful,ive just had my first litter of 4 babies so this was really helpful thankyou.

Your pictures were extremely helpful for correctly seperating my piglets

thanks for all of your help I was about to put a male with a female and my mom said she didn't want any little guinea pigs but thanks to your website I stayed out of trouble.

Yay!  Thank you.  Now, hopefully, I won't have to worry about unwanted pups! Thank you!

Very helpful, my guneapigs just had babies, Im hoping I can sex them now.

Your website and photos were a great deal of help!  I've had guinea pigs for a long time -- but am now up to 23 : )  of them......and was "doubting" my comptetency at sexing them.  Thanks so much for the help and boost of confidence ; )

this was very helpful, as someone just gave me a pig because they didnt want it, and I didnt know what it was!!!

thanks very helpful pictures.  I have two females and a possible male.

I have just discovered this website as I am thinking of buying a guinea pig. I want to learn all about their care as I have never owned one before. Thank you for any information and care.

Thanks for this, this is an awesome resource, definately going in my favourites!! I have my suspicions that one of my girl piggies is a boy. . .

Okay, I'll try again!

great. best website i've found for sexing guinea pigs!

Thanks!  We thought we had a boy, but now we think we have a very pregnant girl!  Thanks for the 411!

Very helpful website, pictures were a great help.

I have baby rabbits and guineapigs and now the two dogs are looking as though the bitch is pregnant so needed information and found that the information that i got was much better than any book thankyou

I love male guinea pigs!

how can you tell the diffrence

i thourt this web site was very helpfull

I am 11 years old too and I have two guinea pigs and one is new and this helped me out a lot!

i`m 11 too and there is very good advice on here

I am 11 and just got a baby Quinea Pig.  I always research any new animals, ususally online before we bring them home. Thank you for all the free information. It's easy to understand.

I am a New Pig owner!!ANy advice is good advice.

Our Guinea Pig doesn't make a sound.....does anyone know why?

Is it sometimes confusing to determine the sex of a pig?

will male guinea pigs try to mount same sex pigs?

how can you tell if they are gona have kids

I hope this helps I'm picking out another pig today and I'd rather not start breeding.

re: Neutereing, please see: www.cavyspirit.com/neutering.htm

A usefull guide to sexing piggies. Isn't it a bad idea to have male piggies neutered though, piggies tollerate anaesthetics poorly and there is a high mortality rate associated with the procedure.

That helps....isn't it kind of obvious though??

Thank you for the information and the various pictures of sexing pigs at various ages.  Disregard the immature comment made on the 19th about it being like "guinea pig play boy."  I applaud you for trying to help others out to prevent homeless piggies in this world.

Well, this site definately has a lot of useful information....you can pretty much consider my home a 'rescue'. Right now I have 7 little piggies that people had to give up for different reasons.  Our original, Pumba, was purchased as a pet for my 2 sons...they can never get out of feeding him because he gets quite vocal if they pass him off (that is one of the reasons I got him for the boys..I grew up around guinea pigs and they will "tattle"!)  But, I have a mommy and 3 3 week old babies, and 2 other adult males.  I do have to admit that I did not realize a boar can make babies at such a young age!!  I do have plenty of cages and supplies..I am always picking things up at flea markets and yard sales.  So, if I can be of any help to anyone, I am in the Beaver County area of PA. Just let me know.  But again, thatnks for taking the time to post such an invaluable site.  This definately took a lot of time and effort.  And to everyone out there.....Have you hugged a piggie today ?!?!?!

Hey! Thanks 4 the info! I found out that my long haired guinea pig was a girl! I thought it was a boy and I named it Spanky!!

HAVE A GUINEA PIG JUST GAVE BIRTH WHAT DO I DO TO CLEAN THEM OR SHOULED I LET THEM GO. THNKU

this is like guinea pig play boy.Discusting!

you have helped me so much with my pigs thank you so much.

I had been given 2 females & one was pregnant & i wish to keep one female & give the others away & sexing has been a real issue. Thanx heaps

Excellent photos / information.  I, too, had two "females" who when onto to have three babies.  Now I'm trying to separate the sexes...

GREAT INFO

Thanx 4 the info cuz i really needed to check that out after i bought a guinea pig at my friends house the other day and i didnt know what it was

I wish that we had seen this information before we had 3 babies we thought we had 2 females together not 1 male and  1 female now we have 3 more babies

Wow !! your pictures where great I thought I was in for a tuff time until I found your great site !!!!!

Thanks for this invaluable visual and written information guide for affirming the sex of my girls :)

In december I bought what I was told to be two male cavies from a local breeder.  Now, sixty or so days later, we have a third cavy (an adorable baby).  Your site has helped me determine the sex of our new male cavy. Obviously I'm not confident in returning to the breeder for sexing.

Thanks for the help.I have 4 babies 2 weeks old and kept looking but all I could tell was that I have two males and two females but didn't which was which. Now I know. Thanks.

Awesome site! Very helpful. I am glad you have this site.

Great site.  Really informative.  With you site I was able to determine the sex of my 2 cavies.  Unfortunately one of them passed on.  Do you know of anyone on the Island of Oahu that ownes/raises cavies?  Thanks for you help!!  Dee

Really great site!!! This is the page that saved little Rusty from getting pregnant at four weeks old, when I still thought she was a boy:) Thank you so much! The pics are so clear now!:D

Your sexing page was so helpfull to me. Thanx soo much

My guinea pig just had babies and we wanted to be sure what they were so Sonic, the daddy, could be around them and the mommy, Potpourri. I'm 11 thanks for the great photos because all my guinea pigs are girls! Guess Sonic needs to visit the Vet now.

My guinea pig just had babies this has been a great help to me so I now know how to sex them properly thanks for such good information.

Great photos and guidance for sexxing the GP.  Pictures and instruction were very helpful.  Thanks

your site really heled me to sex my unexpected guinea pigs my pig only had 2 pups

lots of help, thanks

Our female had babies 2 months ago and is pregnant again.  We checked the babies they are all females and the male we do have was seperated and neutered shortly after the birth of the 3 little ones, the only thing we can figure is he got her again before we were able to seperate.  This page was very helpful in knowing for sure what sex the babies were.  Thank you

Thank you for the Fantastic information

this is a good page, thank you for the information

thank you for the information

expecting babys anyday and now know the difference between males and females a great help many thanks

thanks for the very valuable info! i'm now able to identify the sex of baby guinea pigs easily.

this helped me to sex my two 24 hour old babies

this web site was very helpfull,we have a 1 year old pig.can you have to boys togather?

great information,our girl is due soon....

Thank-you for the excellent information and pictures.  My female guinea pig came from the pet store pregnant.  We didn't realize that until about 3 weeks after getting her.  She was only 4 weeks old when we got her.  She gave birth to 4 very cute and healthy babies 3 days ago.  I'm going to sex them now to avoid any more babies :0)

We just recently had 2 babies your site was very helpful in showing me how to tell the difference between male and female babies. PS> we have 2 baby boys!

in have mom pig that iws giving birth how long are they in labor?

I bought 2 females from Petsmart only to find out that one was a male. We are due to have babies in about 8 weeks. I want to find good homes for them all. We certainly can't keep them all. I could keep the mother and all the daughters, but the father and any brother will have to go!!! Unless there are more boys, I like the boys better actually. THey seem to be more fun!

i think you did a good servise and your helping a lot of people

I recently bought a new piggy as company for my 2 girls, I have just found out (thanks to the pictures) that they sold me a male and NOT a female as thought. I have seperated him as soon as I realise but very worried for my girls as they are over the recommended breeding age. Hopefully they'll be ok. t
They have only been together for 4 days but only time will tell. Any advise aprieciated. Excellent web site!!!! I'll recommend it to my local pet shop!

very good but have a ? how should you hold a young baby pig to determine sxt mine are 16 days old?

This is a very good site. It helps so much!

thanks ever so much now i will really know if its ither a boy or a girlthankyou

thank you very much you site sure helped use to figuar out the sex of our guines pigs

Thanks so much. Your site has helped me. And saved me a trip to the vets.

This is a great site!!!!!!

thanks to you my daughter isn't worried to much about her piggy bitting now she knows tha he can hopfully be curred.

I am grateful for information I have had my guinea pigs to the vet three times and found better help for them here. I phone the vet back and informed them what was wrong with my guinea pigs! Thank-You !!!!!

YOU Are Great

I think i have a girl and a boy but the pet shop i got them from said they were both girls But now i know how to tell thanks to your web site

We bought a female guinea pig that was too young to have babies...she had them three in a half weeks ago!  I was told(from the pet store) that guinea pigs would not start reproducing until at least three months.  Needless to say he is off by himself tonight.  Anyone know if he can be put in a smae cage with the others as long as the cubes are between them??  Would he still be able to mate between the holes in the cubes?  He seems lonley tonight.

To Michelle Taylor: Please read http://www.cavyspirit.com/breeding.htm to see why breeding your pig is dangerous, unnecessary, and contributes to the guinea pig population of the US. Please adopt a same-sex companion for your pig from a shelter or rescue instead.

I have tried to sex my guinea pig still did not come up with any thing I am going to take my pig out to someone shop that can tell me. But if is ag irl and I want to get her to have babies, I know I need to buy a male guinea pig. But how long do I keep the male inthere withher before I would know that she is pregant.

Thanks for the help sexing our new baby, we now are 80% sure it is a girl but will come back in 3 weeks to ckeck any change.

Thank you. I rescued an unwanted 'female' and with your help, discovered he is a male.  I am looking to get him a companion and am relieved to know i have the sex right.  Larry

How long is a guinea pregant? I have a female who is pregant with her second time with us.Becouse we bought her from some one.

Great site and pics.  I was told I had a female and now with your help I've learned it's a male.

Thank you!  It's always frustrated me to go to pet stores and fine the wrong sex in the wrong cage.  Thanks for the fantastic educational tool!  Keep up the good work!

Yowza!  What a useful tool!  We have been keeping our daughter's school's rabbit and guinea pig (newly from the pet store) over the summer.  To everyone's amazement (including the pig's), the pig produced three babies one Sunday morning, almost exactly four weeks ago.  We'd read elsewhere that pigs reach sexual maturity at two months--glad to have found your site now rather than later.  Let's hope we're all still in the clear....

Thanks I could not tell the difference because the pigs were so small but now I know thanks

Thanks for all the pictures, me and my friend were wanting to make some babies, but we didnt know how to tell which pig was which

my female had 4 babies 2 weeks ago. Thanks for such an informative web page. I can sex the young now, to prevent an epqademic !!

I'm so glad to find a website that's not afraid to put enough pictures to help the reader determine the correct sex. My female gave birth to three boys. I 'm glad I knew how to tell, I wouldn't have wanted to keep them with her too long!

Thank you i almost thought one of my girl guinea pigs were a male and when i came here i figured out that she was not really male.Thank you

This is THE FIRST page that gave us enough pics to properly determin the sexes, THANK YOU!

the pig's bum pictures are ferral

great page if you have any questions. we got a young pig this weekend and now we know for sure it is a guy!(6/21/04)

gteat site

re: Kyler

The male is not really "having sex" with his cagemates, but is showing aggressive behavior. I would not put your pig back into the cage because the constant bullying will cause him extreme stress, which I only guess might have been what contributed to your last pig's tragic death. I would definitely take him out of his mother's cage ASAP because female sows may become pregnant right after giving birth, and you surely do not want to inbreed. You are going to have to give him his own cage. You can also try placing some of the new boars in with him once they are born and weaned in a few weeks. You may end up having to seperate some of the new brothers too, because sometimes pigs are just very aggressive (particularly when their is a female around).

that is pretty awesome!!!!!!!!!

we have 2 adolescent cavies of the same age. my boyfriend and his brother said they were both males so we kept them in the same cage. but one, the bigger one always tries mate the smaller one. but the smaller one seems to resist and behaves violently (while squeeling) when ever the bigger one is in heat. i put the smaller one in her mom's cage but the mom will soon give birth and i need to put it back on the old cage. im am scared to put it back because we already lost one cavy (male) when another male had sex with it. help please.

wow thoose pictures were gross and cool at the same time now i know that i have 2 gal gps

ewwwww

Thanx for making such a great site!! Its exactly what me and my friend needed for our new lil' guinea pigs!! PS: Mines all so cute and fluffy!! *hugs Phuffy*

very helpful.  the problem is that i didn't read it before i got a second one.  no wi am pretty sure i have a male and a female.

thank you for this straight forward site

i have two guinea pigs one girl and one boy i have one with me one now

They tricked me! They sold me a male cavy, and thanks to your site I just realized it´s a SHE! I´ve should have known of this site before!!!

Thanks to your site, I have correctly sexed my cavy (she's female, but I was told she was male).  Thanks so much!  Now I can keep her safe from unintended pregnancies by getting her a female companion!

I bought second cavie a month ago, and was told it was a male. But I have come to the conclusion that it is indeed a female with your help. Thank you so much! Now I will not leave her alone with my male. I hope I am not too late to stop a population explosion. (03/23/04)

Thanks!!  We aquired a female at Christmas only to find out she was pregnant. A shock but very fun.  We have 3 healthy babies but I needed to know EXACTLY how to tell the sex.  The pictures were extremely helpful.  Now they can go to their new homes with the confidence of knowing if they are male or female.

You have knowledge than the local vet or pet shop

Just bought a pig today. They told me it was male, it didn't look that way to me, but THANKS to you- now I know it IS!

Thanks.  I have 12 pigs from people dumping them on me.  I love them but they are so much work.  Thanks for the info.

What a wonderful site!

Great information. I'm an agriculture teacher and the sexing photos really help in the classroom

the pictures were a great help especially with our new litter.

Thanx!
