Hello everyone. I have an overdue pregnant guinea pig who is 1 1/2 years old. She is about 75 days pregnant but still eating and drinking and the babies are kicking a lot. I was wondering how we would be able to feel her bone when it separates. We took her to the vet and she has 2 babies inside her. They are kicking and alive and she is very plump. Also, please don't say their pelvic bones fuse because of their age. We got the opinions from 3 exotic vets who said that hip bones never fuse just get closer together. PLEASE HELP
