The Litter Containment Mat.

"These are the interlocking trays that remove and collect kitty litter from paws to prevent felines from tracking litter around the house. The six included trays have 1/2""-deep grates that spread a cat's toe pads and dislodge litter granules as they walk, allowing the detritus to collect inside the tray. Made from durable plastic, the trays use static electricity to attract and hold fine litter dust. The 1'-sq. modular trays interlock on all four sides for customizable set up around a litter box. Grates are removable for ease of emptying the collected litter. Set of Six. Each: 1/2"" H x 12 1/2"" W x 12"" L. (1 lb.)"
