I do have a question about keeping these guys though. When I had them together they were all huddled up together all the time. But since I am unsure if dolphin is really a she I don't want to risk leaving her with the male and getting pregnant right now. Since then she stays in her house way in the back and has built a pretty high nest out of shredded paper.
The male he comes out from time to time but the girl she is rarely seen. Could this be she is lonely? I know rats like being around other rats.
Would it be best to get her a friend, once I find out if she is actually a girl, or just give her as much attention as I can and let it be?
