  • Patent number: 4934317
    Abstract: An animal litter box, readily marketable in kit form, comprises a fresh-litter supporting bottom tray and a litter reservoir with a bottom feeding mechanism. When litter on the bottom tray is soiled, the tray is readily moved past scraping means to dump the soiled litter in a trash receptacle and simultaneously actuate the feeding mechanism to replace the removed soiled litter with fresh litter. The bottom tray has a support which is rotatable about an axis by exerting a force, foot pressure, against a biasing means which returns the bottom tray to its initial position when the force is removed.
