How to tell if my guinea pig is pregnant??
Humping is normally just a sign of working out the hierarchy but now that you say that Hermylee is getting big she may well big pregnant. Firstly check if Jadelee is a girl or not. To do this you have to flip her on her back and gently press around the genital area. http://www.guinealynx.info/sexing.html If Jadelee is a boy then Hermylee could well be pregnant, if Jadelee is a girl then you need to take Hermylee to the vet because she may have a tumour, abcess etc. The average gestation period of a guinea pig is 63 days, when this is over the bubs will be born, fully haired, moving and eating solids within days. If Jadelee is a boy then you need to remove him because Hermylee will come into a big heat anywhere from 2 to 15 hours after giving birth. I would take Hermylee to the vet because they will be able to tell you if she is pregnant or if she has something more serious.
