Abstract
Abstract A throwaway litter box for cats or the like comprising a generally rectangular container partly filled with absorbent granular material. The container includes thereon supports for spacing the bottom of the container from a surface on which it is positioned to prevent moisture condensation on the surface beneath the container, an inwardly extending flange at the open top of the container to minimize spilling of the granular material, and hand grips in the container to facilitate handling of the container. A cover is provided for the container to prevent shifting of the granular material in the container during shipping and storing of the container prior to use. The cover also serves as a pet dish tray when the pet relief structure is in use.
