Bests & Worsts Reviews from Amazon

I have two 13-pound male cats, and the box with the hood is large enough to accomodate them. They started using it right away, along with their other litter boxes in the house. The mechanics of the machine worked nicely, turning on around twenty-minutes after the cat had left the box. Unfortunately, I was sold on the line that this box was odor free. It is not odor free! After two days it stunk worse than their other litter boxes. Poop got stuck in the metal wire scappers, and it filled the small box at the bottom of the machine in less than a week. There is no odor control in the bottom box, poop just sits in there stinking until it drys completely. Needless to say, this box is heading out to the trash.
