How Do I Tell If My Guinea Pig Is Pregnant?

  its been about 31 days since My Male Guinea Pig (Boo) Had Sex With My Female Guinea Pig (Miss. Squiggles) And Shes pretty Heavy.
The gestation period is about 65 days as an average. So if she is pregnant you can clearly palpate the babies. Their spines are all formed at 30 days. Because of the long gestation period the female gets clearly large, oval. Be aware that if she's older than six months her pubic symphysys may have fused already and it will be almost impossible for her to deliver the babies naturally, there's a great risk of dystocia. If she's pregnant talk to a vet and discuss options like c-section, increased calcium and vitamin c necessities.
The difference between an overweight guinea pig and a pregnant guinea pig is that an overweight cavy is usually larger all over, while a pregnant guinea pig has an enlarged, wider lower half that continues to get bigger even if the female's food consumption doesn't increase. So, to answer your question if you guinea pig continues to eat as usual but at the same time continues to expand at the lower end, then most likely than not is pregnant. To be really sure, consult a vet that especializes in small mammals. By the way, if it turns out your guinea pig is pregnant and you can't handle the added responsibility or expense of having new additions to your family, call a rescue shelter in your area. The'll be sure to find a loving home for them.
Take your hand and put it on her stomach, be gentle but push down and put a little pressure, just to feel. You will be able to feel babies in there. You may even wake them up and they will start moving. It is a beautiful thing to feel. I got really good at determining how many babies were going to be born too. Also, pregnant Guinea Pigs take on a big bulb or pear shape when heavily pregnant.
sounds like you're gonna have pups in a month or so. do not leave the boar in the cage with her!
lololol I like how you provided the names! cute! uhmmmm maybe shed be acting weird and sleepy and hungry
Umm .. sounds pregnant to me.
Pick up the guinea pig and put your hand on its belly; if you feel anything moving, then she is with the babies. She will also act like a royal ******.
