I don't know why, but I clicked on this ad:
Never Touch Litter Again
Self-Flushing, Self-Washing Cat Box As Clean as Your Cat
If you have a cat, and don't really like it too much, you should probably look at investing in a CatGenie. It's a toilet, for your cat. I wish I was joking.
There's a video explaining how it all works on their web site, but I have to wonder what kind of freak would buy this thing starting at $249.00. Maybe you can fit it with a Brawndo connector.
