Here’s a timesaver to give you more play time with kitty. These litter box liners have a unique perforated bottom—just lift it and clean litter returns into the box. Throw the dirty litter away with the liner, and the next liner is ready to go. You’ll get a set of 10 durable 3-ply recycled plastic bags and one solid bottom liner. Fits litter pans up to 22"x18".
