I just found this toilet for cats at petco.com. I guess after the cat goes to the bathroom it "flushes" and cleans these granules that are used as the litter. It's a bit pricey but I guess if it worked it's worth it. Anyone own one of these? I'm kind of curious to see if they work. Not that I'd spend that much on a litter box anyway.
