ABSTRACT:
A litter box and pivotal sifting device assembly having an open base portion and a pivotally movable sifting device operably attached thereto. The base portion also has a litter holding wing portion operatively associated therewith and extending upwardly and outwardly therefrom. The pivotal sifting device is initially disposed beneath a layer of loose litter material. Thereafter, the sifting device is pivotally movable up through the litter material to collect clumped absorbent litter and fecal matter wastes thereupon while permitting loose litter material to pass therethrough. The sifting device is pivoted still further to deliver the wastes to a disposal site. Once dumped, the assembly is quickly restored to its clean and ready for use position by rotating the assembly successively onto the first and second angular end walls of the wing portion whereupon in response to gravitational forces, the loose granular litter material flows into the wing portion and thereafter while rotating the assembly in reverse sequence back to its animal use position, the sifting device is automatically, pivotally returned to its operative position in the bottom of the base portion covered with the loose granular litter material.
