Never replace your cat litter again Cats use CatGenie like a clean litter box 1,6 kg (3.5lbs) of comfy Granules to help cats dig and cover For use only with the Catgenie 120 Self Washing Cat Box Tabby Due to high demand and supply issues, the expected arrival date is an estimate only and is not guaranteed. We are sorry for any inconvenience caused. The CatGenie Washable Granules Case will never need replacement but you will need to add additional granules when the level of the granules falls below the line on the bowl. On average you will need to add a few cups a month and a box of granules should last between 4-6 months depending on the number of cats that use the CatGenie. The plastic in the Petnovations CatGenie Washable Granules has been specially formulated to completely biodegrade in your sewer or septic system in about 9 months or less.
