The EZ Clean Litter Mat helps keep litter box messes contained and not spread throughout the house. Litter falls through the large holes on the top layer and stays trapped underneath. The bottom layer is made of a plastic, waterproof film that repels urine and odors. The two layers are attached on just one side so you can easily pull back the top layer and dump the litter into the trash. You can also rinse off the mat to clean liquid messes.
