1. Field of the Invention
The present invention relates to litter handling devices and more particularly pertains to a litter filtering system for filtering animal litter to remove impurities therefrom.
2. Description of the Prior Art
The use of litter handling devices is known in the prior art. More specifically, litter handling devices heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.
Known prior art litter handling devices include U.S. Pat. Nos. 5,211,133; 5,272,999; 5,220,886; 5,178,099; and 5,032,254.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a litter filtering system for filtering animal litter to remove impurities therefrom which includes first and second containers operable for receiving a supply of litter for use by a pet, and a screen assembly 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, wherein the assembly of the containers and screen assembly can 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.
In these respects, the litter filtering system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of filtering animal litter to remove impurities therefrom.
