The PETKIT AutoSeal Cat Litter Disposal System takes the mess and smell out of litter disposal, making it a perfect companion for your daily scooping routine. The best way to dispose of cat litter. An auto-sealing door in the middle keeps odor locked in while you scoop and while waste drops below. The heat-sealing feature seals the bag shut, so you never have to knot, cut, or touch a dirty bag by hand. With room for up to 15 days of waste, it's fewer trash runs, a fresher home, and one less thing to think about.
