Abstract: An improved self cleaning cat box and new method for cleaning a cat litter box is comprised of a litter tray, a rake, and a storage area with a lid, a scraper and a drawer. In operation, a motor propels the rake through the litter. The rake collects waste as it moves forward till it is rotated up and moved over the storage area. The scraper comes down over the waste while the rake is over the storage area, preventing waste from leaving the storage area as the rake retracts. The waste is deposited in the drawer. When waste has accumulated, the drawer may be opened for easy maintenance. The storage area lid has a seal to prevent the escape of unpleasant odors. As the rake returns to its starting position, it back rakes and levels the litter. The rake is then retracted out of the litter and parked behind a baffle.
