ABSTRACT:
A pet litter box made of relatively light weight, easily cleaned material which includes a bottom pan for collecting liquid waste, an upper box which closely interfits with the bottom pan to contain odors in the bottom pan, and a litter tray which is supported by the upper box. The litter tray includes an apertured flat sheet which supports a layer of litter. The litter acts as a liquid waste absorber and odor barrier, while allowing unabsorbed liquid waste to pass downwardly into the bottom pan. The apertured flat sheet is integral with a cellular structure to provide structural rigidity for supporting the weight of a pet without significant downward bowing of the sheet.
