ABSTRACT:
A litter filtering system for filtering animal litter to remove impurities therefrom. The inventive device includes first and second containers operable for receiving a supply of litter for use by a pet. A screen assembly is adapted for positioning over the first container and receiving the second container in an inverted position on top of the first container such that the screen assembly is positioned between the containers. The assembly can then be manually rotated so as to position the first container in an inverted position, whereby the litter is caused to filter through the screen assembly and into the second container.
