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.

[ Accordingly, what is claimed is:] [7.] A litter box assembly comprising: a substantially rectangular base portion having a seating surface; litter holding means attached to said base portion at one end thereof; and a pivotally movable sifting device pivotally mounted to said base portion; said sifting device having a handle, a foraminous, substantially rectangular main screen portion connected to said handle, an angled foraminous screen portion connected to said main screen portion, and pivoting means connected to said angled screen portion, said pivoting means being operably mounted in said base portion to make said sifting device pivotal relative thereto; said litter holding means having a plurality of end walls attached to and disposed at preselected angles relative to each other to provide at least one alternative seating surface for said litter box assembly; said litter box assembly further having a first side wall and a second side wall attached to said base portion and attached to each of said plurality of end walls such that said first side wall and said second side wall are in spaced generally parallel relationship to each other and coact with said plurality of end walls to define said litter holding means for temporarily receiving and holding litter therewithin; said litter being movable into said litter holding means from said open base portion when said litter box assembly is consecutively seated respectively on each of said plurality of end walls until said litter is transferred completely into said litter holding means and said bottom seating surface is completely free of litter for the repositioning of said sifting device into surface-to-surface engagement with said bottom seating surface.
