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 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.
