Sifting cat litter box.
Made of odor and stain resistant durable plastic.
Size:22″L x 15.7″W x 8″
To use and set up: Stack the pans with the sifting screen tray on top and fill with clumping litter. When you lift the sifting screen the litter sifts out into the pan, leaving the clumps that you throw away. Empty the clumps to trash and replace the sifting screen in the empty pan. Move the litter from the full to the empty pan, (add more litter ) re-stack, and your are finished.
