I just got a new mouse for Christmas because recently my only male mouse chase died. I've been trying to breed them for quiet some time so I needed a new male. Well I was really stupid and just put the male mouse in with my three females. Their was one argument that didn't last long and 2 of the females now accept him completely but one of my females is acting strange. She jumps around the cage if any of her roommates get near her Especially the male and squeaks with her tail erect ears back watching the male on the constant. I cant get her to stop and I'm not sure what to do neither of the mice have tried to hurt each other. Can some one give me some advice?
