The Cat Genie claims that it is a self-cleaning toilet for your cat. Using special litter, it scoops the cats poop, flushes it away, and then cleans the litter every time. No mess, no smell, no changing the cat box anymore.
The downsides is that it costs over $300, is kind of ugly, and has to be hooked up to your water. The commercial had the poop draining into your toilet, but I suppose you could have it drain into the sewer. If I could put this thing away in a cabinet that the cats could access so I wouldn’t have to look at it, it might be worth it to get a Cat Genie in the long run. But maybe not?
