A litter box for an animal, typically a pet, comprises a base which holds a drain pan that contains litter. A drawer slides to and from the interior cavity of the base. The drawer holds a funnel and container, for receiving liquid pet waste from the drain pan. A hinged lid pivots downwardly from the front of the base, to rest on the top of the front end of the drawer where it projects from the front of the litter box. The lid provides a step for pet access to the drain pan.
