I have two female chinchillas. The first one, Bella, was about 5/6 months when we got her. We have had her for 5 months now. She is sweet but very standoffish. She also shoots pee here and there with NO warning what so ever. 5 times maximum. We have noticed she is cage aggressive so we no longer take her out, we just let her come out herself. The chinchilla, violet, we just got is about 7 months the owner said. We have had her for a month now and are still having issues introducing them. She is really sweet and we have had no problems with her. They are in separate cages close to each other. We take them out for playtime at the same time but separate them. Before we put them away my girlfriend and i hold them and let them sniff each other. Sometimes one will chatter and sometimes the other will. The first time we put them together in the playpen Bella was chasing violet and she lost a patch of fur but they didn't bark or make noise. We separated them immediately because we were nervous. lol but they didn't get hurt or anything. And the second time we gave them more space so they didn't feel so much pressure. Once again, violet lost fur but no one got hurt. I know they are still getting used to each other and are going to have tiffs but when one loses fur should we separate them right away or just keep them together unless one gets hurt? I don't know what to do. I haven't read much on what to do if one loses a little fur. We do have a huge cage waiting for them as well. Please help and give us some advice!!
