I have a little ebony female, and I just got her at the beginning of the month, and yes, she is housed with a male so could be (Hoping she is) pregnant, and yes, she has most likely been bred before. I weighed her just about three days ago, and she was 573, and this morning she was 622, and I was wondering it's normal that she gained so much weight in so little time. I'm pretty sure she is pregnant, but she couldn't be that far along, maybe a month or a month and a half?
