Don’t scoop the poop! SIFT AWAY cat litter system makes kitty cleanup a breeze! The secret is its clever 3-tray design. The trays are identical, but when turned 180 degrees, they interlock to trap clean litter only. When the top tray is lifted and sifted, the soiled litter and waste remain behind, leaving the bottom trays with clean litter. Just dispose of the waste and reset the trays. Saves you money on cat litter! 17" L x 12-1/2" W x 4-1/2" H.
