When you are choosing a litter pan, make sure that it is easy to clean. Do not purchase anything that is porous, as it will only begin to smell after a few uses. If you use a plastic pan, make sure that it is a coated plastic.
The ideal size is a 12 inch square box. You also want to make sure that there is a inch depth so that the hedgehog can get into the litter box easily but is able to cover the waste after he goes.
Litter boxes can be filled with a number of different types of litter, however, it is recommended that you avoid clumping or clay kitty litter since that can lead to health problems in your hedgehog due to the clay causing impaction.
To keep your hedgehog's litter box fresh, use about 2 tablespoons of baking soda every time you clean the litter box. It will help keep the smell down on the box.
Make sure that the litter box is as far from the food and water dishes as possible.
