There is disclosed a litter box with sifter apparatus for convenient cleaning and servicing of a pet litter box wherein the sifter element is in the form of a basket with a gridlike construction of molded rigid plastic and sloping sides. The grid of the basket is formed of bars of triangular cross-section, each such bar being oriented with the flat side facing the interior of the basket and the apex of the triangle pointing outwardly or downwardly. Spacing between the bars is such that kitty litter will fall through the bars into a conventional litter box, and, using a knifelike action of the triangular bars, the basket may be pressed back into the litter in the litter box after using the basket to remove solid waste. A frame around the top of the basket rigidifies the structure and serves as a handle on each end of the basket which is provided with openings for hand holds. Support bars are optionally included around the side of the basket and across the bottom of the basket transverse to the grid forming bars, and these also are preferably of triangular cross-section.
