I also should have said that yes, you can use clay litter BUT it cannot being the clumping kind (that would kill a bunny when it clumps up in his gut), and it cannot have chemicals in it.

So you can use the cheap stuff. The problem is, for some unknown reason, bunnies LOVE to eat their litter. My rabbit specialist vet says that a "little" Carefresh is ok, but if the bun is eating a lot there's a problem......I just have no idea what "a little" and "a lot" are.... What I have done when $'s are tight is put the baking soda down with an inch or so of clay litter on top of it and then put an inch or so of CareFresh on top of that.

Bunny #8 is really a sanctuary bunny I have been nursing back to health...for whatever reason she likes to sit in her pee and as a result has urine scald on her fanny and has lost all of her fur down there. The way I overcame THAT wlittle foible is we bought her a kiddie wading pool and out down a layer of newspaper, then baking soda, then clay little and the top layer is several inches of shredded paper. THese layers draw the moisture down and keeps her dry and all her fur has grown back....sometimes I am just too clever!!!! (). So what I am saying is you could use shredded paper as well as clay litter. It would need to be changed pretty often to avoid developing an ordor.

Then there's other folks I know who just use timothy hay in the litter box and that way the bun can eat and do his thing at the same time. The bunny WILL NOT eat the soiled hay.

And don't get disgusted if Thelmer ends up eventually sleeping or lounging in his litter box....we aren't sure why but bunnies just love to do that. Personally I think they feel safe in something that has sides to it. And it's all the more reason to be sure to keep the litter box clean! Good luck! He sure is a cutie!!!!
