I need suggestions. I have my approx. 6 month old boy in with my approx 1 month old girl. I just got them three days ago. All went wonderfully, they seemed to get along just great. I wanted to let her have one litter, and then seperate the boy and girls. Well, I swung by the cage just a bit ago and found that the girl had a big gash on her nose, and it had a layer of fresh blood on it. Any suggestions? I want desperately to keep them together.
