Beyond a cat litter mat, the Stikitty(R) is a paw-cleaning pad. The Stikitty uses clean room technology to proactively clean dirt, dust, and debris from your cat"s paws, creating a healthier, happier pet and a cleaner home. With 20 sticky layers, one Stikitty can last up to 6 months. The lightweight Stikitty cleans easily and doesn"t require shaking or vacuuming. When the top layer is fully used, simply remove it to expose the next clean layer. It comes in two sizes to meet a range of space requirements. Comfortable for cats" paws, the Stikitty is sticky enough for litter but not so sticky that it bothers even the most skittish cat"s paws!
