The CatGenie Washable Granules will never need replacement but it is important to add additional granules when the level of the granules fall below the road at the bowl. On average it is important to add a couple of cups a month and a box of granules will have to last between 4-6 months depending at the choice of cats that use the CatGenie. The plastic within the CatGenie Washable Granules has been specially formulated to totally biodegrade to your sewer or septic system in about 9 months or less.
