This smartly designed unit features two nesting pans and a sifting screen. Stack the pans with the sifting screen on top and fill with clumping litter. When you lift the sifting screen the litter sifts out into the pan, leaving clumps that you throw away. Replace the sifting screen in the empty pan, move the litter from the full to the empty pan, re-stack, and you're finished! Roomy pan features a locking lid with filter, carrying handle and removable odor controlling door. Size  21 ¾" x 17 ¾" x 19" Color Green Made of durable, easy to clean plastic.
