I just recently bought a fancy mouse. Well I bought two. I named one Rambo and the other Gizmo. After a week, Rambo was making Gizmo bleed. So I went to the local pet shop and was told that I could get a smaller male mouse to go along with Gizmo in order to replace Rambo. Thus, I adopted a regular feeder mouse. (Gorilla) Now Gizmo picks on Gorilla endlessly. I had no idea what to do.
Well, I went yet again back to the pet shop. The lady there said maybe another feeder mouse would help. So now I have 3 male mice living together. The thing is, the new mouse (not yet named) is more dominant than Gizmo. So Gorilla is still being picked on by Gizmo. I have no idea on this earth what to do.
I put Gizmo in a roller ball inside the cage for a little while to see if maybe just being with Gorilla and watching him would help. Please please please help me :/
