ABSTRACT:
An automatic or semiautomatic cat litter box and cleaning mechanism which is compact and simple in design is provided. The device has an enclosed housing with a pivotable top lid which can be opened to allow periodic cleaning when needed. A sifting screen is rotated by a crankshaft mechanism so as to traverse a 360.degree. radial arc through the interior portion of the housing, passing through the soiled litter and removing the waste. When the sifting screen has completed its cycle, it stops on top of a storage container upside down so as to drop any sifted cat waste into the storage container which can be removed from the housing and the waste can be periodically disposed of. Guide tracks are also provided to direct the sifting screen as it traverses its cleaning cycle with a pair of torsion spring members which provide an energizing force to the sifting screen as it is guided along the tracks to subsequently be released with an impact force against the top portion of the storage container in order to dislodge any waste material caught in the perforations of the sifting screen.
