I have tried a couple of different types of litter for my CH baby and she seems to prefer the Feline Pine clumping litter (which is basically a pile of saw dust that clumps). Because she is still a kitten she basically "throws" herself into the litter box, so I can use a regular litter box, but with no lid. Needless to say that the litter gets scattered around but at least with the Feline Pine it is easy to clean up
