A cat litter box having a side wall defining an interior and a bottom surface within the interior formed from a main door and multiple secondary doors which form on opening. Each door includes a slat connected below the slatted edge on an underside thereof traveling most of a length of the slatted edge, and the doors are hingedly attached to the side wall of the housing. Provided is a means for manipulating the main door upwards and downwards such that the main free edge can be pushed against the slat of an adjacent one of the secondary doors to provide a downward force against each the secondary door to reveal the opening. In this manner, any contained soiled litter can periodically be dumped and the contents removed, resulting in an easy-to-use, sanitary cat litter box system.
