You are not alone if your cat tracks the cat litter all over the floor when they come out of their litter box. Our cat litter mat solves this problem. Our exclusive sand blocking mesh technology captures litter from your cat's paws and traps it so it doesn't get on your floor. The large holes in the top layer allow the sand to fall through the next layer. We have tested this litter mat with cat litter such as clay, glass, corn, etc. Works with almost all cat litter.
