An improved sanitary facility for pets is provided for the collecting, removing and disposing of small animal excrement without the attendant mess and odor heretofore experienced. A rotatable chamber which contains pet litter, sand or other suitable material, has a first closeable opening 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 continuously urged, by the combined action of gravity and the incline of the filter means, toward a second sealable opening in the chamber. The separated matter is expelled from the chamber through the second opening and deposited in an appropriate receptacle. Means are provided to prevent 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.
