I rescued a brother and sister rabbit from a serious hoarder who was willing to give some up. They were really in a terrible situation. Male and female siblings and mother were all housed together in one small pet store cage. The babies are anywhere from 8-12 weeks old. She told me they were only 8 but they don't really look that young to me. I have the male and female separated since they came home. It's been 5 days. The female the whole time has felt like she has a baseball inside her. Her tummy is round and hard. I don't know if it's fatness for babies. Both the female and male appear healthy and are eating lots of hay and pellets and drinking lots of water. Poop appears normal. I just am worried and don't know how to tell for sure. Thank you for any help!
