My three girls poop all over the shelves in their cage. I have tried to litter train them, but they just never got the hang of it. (My boys do it just fine) I try to wipe the shelves off, but mostly I end up having to take them out and wash them every day, something I'm not thrilled with. I saw in some of the photos people have posted that their shelves are covered with cloth, and I've always wanted to do that but I'm wondering if it would be too much work to keep clean. I'm looking for suggestions and also directions for covering the shelves. Thanks!
