ABSTRACT:
A litter box system and method for containing and separating animal waste from litter includes a first box and a second box forming a container which houses the litter, a floor card, and a cover sheet for absorbing odors. The litter box system also includes an additional floor card for use during the cleaning process, which includes installation of the additional floor card, a clean cover sheet, and a filter bag. The litter box system is inverted, depositing the litter into the filter bag for filtering litter through apertures in the filter bag, while retaining animal waste within the filter bag for disposal. Each of the boxes is substantially identical having an opening for passage of animal waste into the litter box system. A flange surrounds the opening for helping to retain the litter within the litter box system during use by an animal. The cover sheet may be coated with a protective material, such as wax, for substantially preventing the passage of liquid animal waste therethrough. Handles attached to the first and second boxes, floor cards, and filter bag enable a person to grasp the handles for manipulation of the boxes, floor cards, and filter bag. An alternative embodiment of the litter box system, which utilizes a plurality of cover sheets or a plurality of cover sheets and filter bags positioned alternately together within one of the boxes, does not need to be inverted to remove the soiled cover sheets.
