Litterbox When looking for a litterbox, look for something with sides at least 3 inches high all the way around. Any lower, and the litter will be all over the floor. Small cat litterboxes work fine, so do rubbermaid shoe boxes from a discount store. Triangle litterboxes work okay for some ferrets, most ferrets like to be able to put their whole body in the litterbox to go. The litterbox will need to be secured in the cage by something.
Binder clips work well, so does bungee cord and string.
Whatever you use, you will want something that you can easily remove, but not the ferrets. You will also want a few litterboxes to strategically place around your home in places that your ferret will be. Most ferrets do not like to have to travel far to find a litterbox. Food When looking for a good ferret food, check the back for the ingredients. Just because a food is labeled for ferrets does not mean that it is necessarily good for ferrets.
