Abstract

Abstract A commode for use by pets is adapted to contain litter material and includes an opened mouth rigid base having a disposable container, such as a plastic bag, nested within the hollow interior of the base, the base supporting from below an opened mouth box containing the litter material. A closure in the form of a slidable tray supports the litter material from below and is adapted to close a lower opening in the box, the closure being movable to an open position to enable used litter material to fall under the force of gravity through the lower opening and into the disposable container. When the closure is moved to its closed position, it effectively seals the open disposable container within the base so that the used litter material may be stored therein for relatively long periods of time. The lower opening in the box is substantially smaller in size than the mouth of the disposable container, and in one embodiment of the invention, the box includes inner and outer walls with the inner walls sloping inwardly and terminating in the lower opening. A wiping blade removes used litter material from the closure as it is moved to its open position and serves to retain the litter material within the box.
