We only sell our litter in pet specialty stores, where pet care comes first. Ever Clean® Premium Clumping Cat Litter is available only at pet specialty stores. Smaller pet stores have the 14 lb. carton sizes and some carry the 40 lb. pail, while larger pet specialty stores, such as Petco and PetSmart, stock the 14 lb. and 25 lb. sizes. Additionally, some veterinary clinics offer Ever Clean® Premium Clumping Cat litter.
