A hinge of single piece construction particularly adapted for providing a removable pivotal attachment for a raised cover on a cat litter box wherein the rearward ends of the litter container and cover are each provided with vertical slots positioned such that upon the cover being disposed on the container in a closed position the slots on the cover are disposed adjacently above and in axial alignment with the slots on the litter container. The hinge defines a curvilinear depending tab portion adapted to extend through one of the aligned pairs of slots against a portion of the litter box and be removably retained in a snug fitment within the slot in the litter container. The tab portion of the hinge member merges into a curvilinear guide portion extending upwardly and rearwardly from the tab portion which merges into a cover support portion. Upon the tab portions of a pair of hinges being extended through the aligned vertical slots and the forward end of the cover being raised from the container, the cover is caused to pivot rearwardly on the container by the curvilinear guide portions of the hinges until a raised rear wall portion of the cover abuts the cover support portions of the hinges causing the tab position of the hinges to bear against the litter box whereupon the cover rests on the support portions of the hinges in a fully open position without the need for additional support while providing unobstructed access to the litter container.
