Back to Basics Here
My Tony likes regular, non-clumping clay litter. The stuff I use is from Dollar General, because it's a natural light tan, undyed litter. The dye in blue-green clay litter masks the fact that it's made of dark clay, which causes soiling problems when it's tracked onto light carpet.
Tony has a stainless-steel litter box, which is the greatest invention since the WHEEL, I swear. It cleans truly clean, without the dirt-holding srratches that plastic boxes get. And it's way deeper than plastic boxes, which controls the flinging of litter a little bit. About $20 on sale at PetSmart. Expensive for a non-automatic litter box, but hey, you'll never have to buy another one.
It gets scooped daily, topped up as needed, and completely changed weekly after a scrubbing with soap, hot water and bleach.
