Cedar Fresh Scoop flushable clumping cat litter uses real western red cedar and a special ingredient to very effectively control unpleasant cat tray odors by a significantly slow odor- causing bacterial process, stopping odors before they are created. Cedar Fresh's natural clay granules coat and trap waste, forming easy-to- remove clumps through your toilet or sewer system. Replace only the used litter, saving time and money. The remaining litter is clean and smells Cedar Fresh.
