The Blackhole Cat Litter Mat is a large size rectangular 30″ x 23″ (Pink) that helps keep litter from being tracked or scattered across your floors by trapping it in our dual-layer design. This mat features a honeycomb design that holds tiny pieces of litter that fall between the layers, automatically catching debris as cats exit their litter box. The Blackhole Cat Litter Mat is easy to empty and clean, and is perfect for supporting any type of cat litter including clay, crystal, corn, clumping, wheat, and pellets.
