Abstract: An improved sanitary facility for pets for the collecting, removing and disposing of small animal excrement without the attendant mess and odor heretofore experienced, uses a rotatable chamber which contains pet litter, sand or other suitable material. A first opening is provided for animal ingress and egress, and a second opening for expulsion of separated waste. Filter means, disposed circumferentially within the chamber, selectively separate solid excrement and agglomerated matter from unsoiled litter as the chamber is rotated. The separated waste is urged, by the action of gravity on the inclined filter means, toward a sealable second opening in the chamber. The separated matter is expelled from the chamber through the second opening and deposited in an attached receptacle. The media's weight prevents rotation of the chamber during use by the animal. Means are also provided for automatically sealing the second opening to prevent odor from escaping the chamber.
