The PetFusion ToughGrip Cat Litter Mat is constructed of premium FDA-grade Silicone that is non-porous, waterproof, and prevents the absorption of odors. Durable yet comfortable for your cat to walk on and release cat litter. Flexible and easy to clean. The ToughGrip Cat Litter Mat is great at trapping cat litter and the thoughtful design features elevated inner ridges and an outlier to effectively contain pesky cat litter. The large surface area allows greater range when a cat exits their litter box. Easy to clean with a flexible option for cleaning. Broom sweep, vacuum, or sponge. The litter remains on the surface recesses but unlike traditional cat litter mats, it no longer is trapped from view or reach. Pet parents can save money by simply folding and pouring clean litter back into the cat litter box. Includes side spout and anti-slip traction. Built to last for years and years and will never fade, break or lose its shape. We recommend butting the mat up against the litter box exit for maximum litter mat coverage.
