if you don't buy the male mice at the same time while their in the same cage they would fight bitterly but 2 females might not have a problem with each other but the safest way to get 2 mice at a time is from the same cage.
no they will fight, and some babies may die.
You can put a new mouse in the same cage as another, but if your mouse prefers living alone, don't put the mouse in the cage. The older mouse should be better off solitary.
No.....................Dont do that they will fight and try to kill each other
No, that's not a good idea. The Gunineapig will most likely pick a fight with the mouse and kill it. So no.
in a cage
Wood shavings
yes
if a mouse can stick it's head through an area, it can get it's body through. if your unsure if your mouse can get out of a cage or not, put the mouse in the cage and close the doors of the cage, then put cage(with mouse in it) in bathtub overnight. if mouse gets out, your mouse will be safe in the bathtub(shut the drain of the bathtub) I hope this info will help
no
Probably not. But I read a book in my school library about gerbils and the author of it said that one of his friends put a gerbil and a mouse together in a cage and they worked out OK.
Yes, I would put the adult male in another cage to be on the safe side. Check with a pet store near you. They should be able to provide you with some good information when it comes to breeding.
No.They will fight
