US Patent 10159214 Easy clean animal litter box

An animal litter box is designed for convenient cleaning. An animal leaves waste that is generally made up of clumps and fecal material inside or on top of animal litter. A flexible and lift-able tray is immersed in the animal litter. To clean the litter box, the tray is lifted up which strains the pet waste out of the animal litter. The tray is rotated further so the animal waste is conveniently discharged into a waste bag. The tray is returned to position for re-use by rotating the litter box so as to drain the animal litter away from the tray's normal position. The litter box is rotated back to normal position, and the tray and litter then are repositioned into a re-usable litter box.
