The Litter Locker System is proven to help Cat Owners dispose of litter clumps easily and keep their home smelling fresh. Cat Lovers use Litter Locker because soiled cat litter must be scooped from litter on a daily basis. Disposing of soiled litter in your home trash or outside is a nuisance – especially when keeping a clean litter box and controlling odor is of primary concern. Litter Locker refills are part of an easy-to-use system that locks in odors.
