This is possibly the coolest litter box ever

I've seen the robotic autocleaning litter boxes before, but I think this one takes the cake. (cat litter cake? ew)

It hooks up to your toilet to auto clean and flush all the poop.

Man, I love technology. I just wish I had someplace I could hook it up -- my bathroom is a wee bit small to have a litterbox in it.
