A cat litter box assembly includes a plurality of stackable pans having sloped sides and a filtering mechanism for sifting pet waste from clean litter. The filtering mechanism includes a grate having offset openings in a bottom and side of each pan. The openings are staggered such that openings in an upper pan are on an opposite side from openings in a lower pan to ensure a solid structure which maintains both pet waste and litter therein. |
