Pieviev Honeycomb Cat Litter Trapping Mat, 76 x 61cm Double-Layer, Grey

A double-layer honeycomb litter mat that catches tracked litter before it reaches the floor: paws sink through the top layer, litter falls through the holes, and a waterproof bottom layer stops leaks and vomit from soaking through. Just lift and dump the litter back in the box. Amazon's Choice, 45,800+ reviews, currently 33% off.
