  • Publication number: 20060185607
    Abstract: A litter box safety guard. The guard is affixed to a top portion of a cat litter box cover for preventing other pets and children from entering the litter box cover or otherwise gaining access to the litter material within the cover. The guard comprises a upper member affixed to a top surface of the cover, a front member affixed to and extending downwardly from the top member, a floor member extending from the front member and a support member for resting on a bottom edge of the cover opening. The litter box safety guard thereby functions as a barrier to dogs and children attempting to enter the litter box cover, while permitting a cat to easily crawl through the safety guard to enter the litter box cover. The litter box safety guard does not interfere with separation of the top and bottom portions of the litter box cover to dean or replace the litter material.
