Vibrant Life Sifting Litter Pan makes it easy to keep your cat's personal area clean and eliminates the need to scoop. This sifting pan system includes two durable plastic open pans from 100% post-industrial recycled material, and one sifting tray. The reinforced bottom of the open pans maintains strength, and the rolled edges make it easy to pick up. To use: Place the sifting tray between pans. Fill stacked pans with litter. To clean, pour contents of the dirty pan into the empty pan with sifting tray on top. Simply lift the sifting tray and shake. Litter will fall through, allowing you to dispose of cat waste easily. Reassemble pans and sifter tray after disposal and add additional clean litter if needed.
