my bunny has a litter box and he only pees in that box. I have about 2 layers of newspaper in the box and a pretty thick layer of cat litter bedding (its made out of wheatgrass and it turns into a powder form when its wet). This setting works really well with my bunny and I only need to clean it once about every week or so. the bedding is made of wheatgrass so don't worry about the bunny eating it. ^^ but try not to use the cat litter sand that will get into big solids when it gets wet, I heard that those are not good for bunnys.
