3 pack of litter trays will last approximately 3 months for 1 cat, 6 weeks for 2 cats, and 3 weeks for 3-4 cats.
Each replacement litter tray includes a bag of premium crystal cat litter and lid for quick and easy litter maintenance. Simply slide the new litter tray under your ScoopFree Original or ScoopFree Ultra Litter Box and let it do the rest of the work for you! We recommend replacing your cat's litter tray every 4 weeks for 1 cat, every 2 weeks for 2 cats and each week for 3 or 4 cats.
