Activated charcoal is bonded to the litter and activated charcoal granules are mixed among the litter granules. Extra activated charcoal eliminates odors on contact by grabbing odors and holding them to the surface. Inhibits Odor An antimicrobial agent is added to inhibit the growth of odor-causing bacteria. This 99.9% dust-free premium litter contains larger clay granules for reduced tracking. Ever Clean litter's highly absorbent granules form solid clumps. Features a fragrance-free formula for cats (and people!) sensitive to scent.
