Looking for an automatic litter box that does a little more than just rake? The LitterMaid Elite Basic Advanced Automatic Self-Cleaning Cat Litter Box series adds a new range of features and a modern, sleek design to take automatic litter cleaning to a new level. You get an option to program the box to sleep during quiet hours, an ionic air cleaner for added freshness and more options for accessories to give you the most control over your litter box area. An electric eye senses when a cat has visited the box, and 10 minutes after departure, automatically rakes any waste into an air-tight waste receptacle. Ionic air cleaner will run during rake cycle, neutralizing odors immediately.
