The Dr. Elsey's Cat Attract Clumping Clay Cat Litter features a natural herb attractant to help bring your furbaby to the litter box (sold separately) and train him to keep coming back! In addition to the herb attractant, this litter features a paw-some texture and particle size to help solve litter box problems. A natural chlorophyll odor control makes it purr-fect for single or multi-cat families, and it creates strong clumps for easy cleaning.
