Try this - you won't go back!
We have the cat's litter box in our kitchen, so you can imagine the unplesantness of cooking or eating in a kitchen that smells of cat feces. Fuller's earth never clumped that well, and the box would have to be disinfected every 4 days. I've tried other clumping brands, and while they'd clump, you could still smell the cat feces. Golden Grey Master clumps very well, and not a smell in our kitchen, even directly after a cat's bowel movement!
