Abstract
A disposable cat litter box is disclosed comprising a liner pan for receiving cat litter, with the liner pan having an open top, bottom and sides and cat litter disposed in the liner pan. A disposal bag having an opening at least equal to the bottom of the liner pan and a drawstring around the opening is attached to the bottom of the exterior of the liner pan with the opening of the disposal bag around the sides of the liner pan. A covering lid is secured to the top of the liner pan to hold the cat litter inside the liner pan with a tear cord for removing the lid from the liner pan to expose the cat litter during use. After use, pulling on the drawstring causes the opening of the bag to cover the open top and fully enclose the liner pan and any used cat litter therein. Other embodiments are also disclosed.
