Abstract
A manual litter box provides various advantages over the prior art. In particular, in one embodiment, the manual litter box is configured to use a disposable cartridge which may include a litter compartment and a waste compartment. In another embodiment, the cartridge may be non-compartmentalized. The cartridge may be disposable, thus eliminating the need for the user to clean the litter tray and handle heavy litter containers. In other embodiments, the system includes a rake assembly configured with a manual shuttle chassis drive assembly that is protected from contamination. In accordance with another embodiment of the invention, the manual litter box is configured to be used with all types of litter including crystal type litter.
