What do you put on the bottom of a mouse cage?

Put at least three inches of mouse-safe bedding on the bottom of the cage. Choose bedding made of pelleted paper, non-aromatic wood shavings like aspen or even hay. You can also provide different types of bedding so your mice can decide what to build their nests with. Putting more absorbent litter like paper in areas where mice like to use the toilet can help with odor control.

What is the difference between mouse bedding and litter?

The difference between mouse bedding and litter is that you put mouse litter in a litter box for elimination and bedding at the bottom of the cage for resting, digging and playing. If your mouse does not use a litter box, your mouse bedding will serve the same function as litter, catching waste and absorbing moisture and odor. The best substrates for mouse bedding often work well in a litter box, as well. Just be sure to use different substrates for bedding and for litter so your mouse knows where to "go".

Do mice need bedding and litter in their cage?

Usually, mice do need bedding and litter in their cage, although you can just use bedding throughout if your mouse cage doesn't have a litter box. Choose an absorbent, mouse-safe bedding and/or litter like paper or aspen wood shavings. Pellet litters can work well as bedding and litter for mice, as well.
