Keep mess off of your floor and where it belongs with Fresh Kitty The Grate Cat Litter Mat. This mat features deep-pocketed dual-layers that trap litter so it can be cycled back into the box. The large openings on the top layer are soft on your kitty’s paws and allow litter to fall through to the second layer. The bottom layer is made of a plastic, waterproof film that repels urine and odors.
