Washable Granules R973

If you use the original CatGenie 60 Self-Cleaning Litter Box or the CatGenie 120 Self-Cleaning Litter Box for a maintenance-free, odor-free, and germ-free cat environment, you’ll need to replace its Washable Granules every four to six months. These cat-safe granules never need changing, just replenishment. The CatGenie Washable Granules satisfy a cat’s need to dig and cover. It is made of a dust free, non-toxic combination of natural and synthetic biodegradable materials that will degrade in septic systems within 9 months.
