A self-cleaning pet litter box assembly for separation and removal of clumped material from clean litter material includes an open-top pet litter container for holding litter and being mounted for rotation on a substantially horizontal plane, a conveyor having an axis and an exit end, being positioned to extend into the container to contact litter within the container and rotating about the axis so as to separate clumped material from clean litter material and direct the separated-out clumped material away toward the exit end, and a drive mechanism operatively connected to at least one of the container and the conveyor to rotate the container.
