The surface of the paw, rectangle shaped mat is covered in plastic loops which gently brush your cat's paws, removing any leftover litter. The litter stays on the mat and your cat's paws stay clean. The plastic loops are very soft and pleasant to touch so this is a good mat for sensitive cats. The mat is very easy to keep clean and the litter is quickly removed, either by shaking the mat or by vacuuming it. Since the mat is made from PVC it can also be wiped clean if necessary. This practical litter tray mat puts an end to cat litter all over your house.
