Imperial Cat's Black Litter Mat has a soft, grassy texture that is gentle on the cat's paws but tough on litter tracking, according to the manufacturer. It is made with heavy-duty, marine-grade carpeting that prevents litter from spreading throughout the home while protecting the floor from grit and mess, the company states. The U.S.-made mat is tough, durable, fade-resistant and extra large (36 in. by 30 in.) to provide protection beneath and well outside the edges of the litterbox, the company adds.
