Head over to Confessions of an Overworked Mom and win a Litter Robot!
This is a covered self cleaning cat litter box that changes the litter for you! The globe on the top holds the litter. It has a entry door for the kitty. The largee waste drawer below holds the waste in a bag until you empty it. The globe on top spins and the waste is caught and ends up in the drawer!
