PREVENT URINE LEAKS - Our stainless steel litter box features a sturdy 6-inch high-sided outer shell and a 4-inch top cover. The premium inverted board and overlapping design effectively keep urine contained within the metal cat litter box, preventing it from leaking through gaps. This design also addresses the issue of litter scattering when cats dig. It completely solves the problems of urine leaks and cat litter spills, making it a godsend for cats with frequent and high urination. FULLY ENCLOSED AND SEMI-ENCLOSED - Our stainless steel cat litter box features an easy-to-assemble, 3-layer detachable shell that offers both fully enclosed and semi-enclosed configurations. The fully enclosed setup prevents odor from spreading, effectively stops urine leaks, and provides privacy for your cat.
