A self-cleaning cat litter box is provided which consists of a housing having a floor, side walls, and end walls with an open top, so that a cat can enter. A platform is pivotally mounted at one end proximate one of the end walls of the housing, so that the cat can squat thereon and defecate. A mechanism, activated by the weight of the cat on the platform, is for lifting the platform up on an angle, spraying water upon the platform and lowering the platform back to its original position after the cat leaves the platform. A drain is located at the pivoted end of the platform to carry the waste water therefrom. A mechanism is fluidly connected to the drain for liquefying any solid waste within the waste water so that all of the waste water can be flushed out.

A self-cleaning cat liter box which comprises: a) a housing having a floor, side walls and end walls with an open top, so that a cat can enter; b) a platform pivotally mounted at one end proximate one of the end walls of said housing, so that the cat can squat thereof and defecate; c) means located at an opposite end of said platform activated by the weight of said cat one said platform, for activating a lifting mechanism for lifting said platform up on an angle, spraying water upon said platform and lowering said platform back to its original position after the cat leaves said platform; d) a drain aligned with and located at said one end of said platform to carry the waste water therefrom; and e) means fluidly connected to said drain for liquefying any solid waste within the waste water so that all of the waste water can be flushed out; further including: f) said platform having four raised sides thereabout, with the raised side proximate said drain being perforated for drainage; g) a screen extending across said platform and supported on the four raised sides, so that when the cat urinates the urine will pass directly through said screen and collect in said platform until said platform is lifted up on an angle; h) a rod mounted to the top edge of said platform oppositely from the perforated raised side; and i) a plurality of rock shaped stringed beads, each connected at one end to said rod with its free end proximate said drain to remain loose to cover said screen as simulated cat litter, allowing the cat to shuffle said stringed beads on said screen to bury the waste, so that when said platform is lifted and sprayed with water, said stringed beads will be cleaned and returned to their original positions on said screen; wherein said lifting, spraying and lowering means includes: j) a micro switch mounted to the floor of said housing below a free edge of said platform which will close when the cat is upon said platform; k) a power source electrically connected to one side of said micro switch; l) a timer electrically connected to other side of said micro switch; m) a water pump electrically connected to said timer and fluidly connected to a water supply pipe; n) said lifting mechanism comprising a hydraulic lift fluidly connected to said water pump and engaging said platform at a point spaced from said one end to lift and lower said platform; o) a valve fluidly connected to the water supply pipe and electrically connected to said timer; and p) a plurality of water jets fluidly connected to said valve and extending above and about said platform to flush the waste into said drain.
