Keep your kitty happy and your floor clean with the IRIS Top Entry Cat Litter Box. Your feline friend will love all the space that the top access offers—it gives her more room to move around without making a mess. The grooves on the lid work as a built-in mat, preventing litter from scattering when your paw-tner leaves the litter box; the lid weight capacity is 20 pounds. The rounded shape and the included litter scoop allow for quick, hassle-free cleaning! Plus, the litter liner is not required for use
