I really like how well this self cleaning litter box reduces the amount of time I need to clean my kitty's litter box.  It was simple and quick to set up and easy to dispose of the litter tray.  The crystal litter absorbs urine and dries up the solid waste so it controls odor very well and is covered by a waste trap.  There is almost no litter tracking and is dust free which is something that I really like.  This litter box is great for any cat owner. It works great.
