They can, just sometimes better not to. Mice are very small & flexible. Wire cages need to have very small bar spacing - 1.5 cm or less - to avoid them getting out.
In cages.
they can sleep in their cages
no the mouse will be eaten and they fight
No they cant because there are plenty of predators that can tear a cage apart and gobble up the mouse/mice
if it doesnt have thin tunnels then yes... i think lol NO NO NO!!!!!! hamster cages are TOTALLY unsuitable for mice as they have calapsible rib cages. A suitable cage is a fully plastic cage with NO bars. Or a fish tank with a decent lid- hope this helps
only when the mice have been good and cleaned their cages.
Usually wire ones as they can climb on them.
yes make both mice live in two separate cages till they get use to each other then introduce in a contained area with tubes and boxes. then they can back away and start the interaction on their own.
Depending on how many mice there are (obviously the more mice, the more room needed) an old aquarium would be good but you may want to add more ventilation. Also a bin cage is really good. (which is what i use for my mouse) research ''bin cages'' and it will show you what they are, and how to make them. Have fun with your mice/mouse!
About £15 - £55 Depends How Big Or How Hi Tech The Cage Is
No, generally diffrent types of mice do not go good together, especially if they are not baby mice. They would probably fight and theres a 50/50 chance they could kill each other. I would strongly recommend keeping them in separate cages, but the cages could be right next to each other. Hope I helped!
Not in and of themselves no, but if you fail to clean their cages of excess food, or leave spilled food on the floor, the food will attract mice.
