ABSTRACT:
A spring loaded platform mounted on a base for downward movement in response to the application of the weight of a pet thereon carries a litter pan in which are vertically nested a plurality of removeable screened pans for sifting a litter medium and disposing of pet excrement. A support upstanding from the base carries an aerosol can of deodorant positioned for spraying the litter medium. A linkage carried on the support includes an arm for actuating the valve and nozzle assembly of the can in response to the upward movement of the platform as a pet leaves the litter pan. The upper movement is detected by a feeler portion of the linkage.
