ABSTRACT:
An animal litter box is disclosed for automatically separating waste materials from animal litter. A rotating cylinder is provided with an internal surface for receiving the animal litter and waste materials. A perforated surface has one end fixed to the internal surface of the rotating cylinder so that as the cylinder is rotated, the animal litter and waste materials fall onto the perforated surface. The perforated surface includes openings sized to permit the animal litter to fall through the perforated surface and sized to capture the waste materials upon the perforated surface. A collection assembly is coupled to the perforated surface so that as the rotating cylinder continues to rotate, the waste materials supported on the perforated surface are guided to the collection assembly and are thereafter conducted to a waste reservoir. After the rotating cylinder has been rotated 360.degree., the waste has been separated from the animal litter and is stored in the reservoir with the animal litter ready to receive new kitty urine and solid waste materials.
