  • Patent number: 5178099
    Abstract: A pet privy which separates coagulated granular absorbent litter material and feces from uncoagulated granular absorbent litter material, composed generally of a litter box component pivotally connected with respect to a support frame. The litter box component, in turn, is composed generally of a tray for holding granular absorbent litter material, a hood member connected with the tray having a pet access port at a frontwall thereof and a discharge chute at a rearwall thereof, a retention chamber adjacent the rearwall of the hood member, a filter grid overlying the retention chamber, a discharge funnel overlying the retention chamber and adjacent the filter grid, and a disposal bag removably connected with the discharge chute. In operation, when the granular absorbent litter material requires servicing, the user simply pivots the litter box component on the support frame, thereby causing the granular absorbent litter material to slide toward the rearwall.
