The Cloud Control™ patented formula is 99.9% Dust Free and will make daily litter maintenance a BREEZE. That’s because Dander Shield Technology™ helps reduce airborne dander when scooping and the Hypoallergenic light scent is free of heavy perfumes. Extra strength formula for Multi-Cat homes. This advanced clumping litter forms an odor-containing seal around urine and feces. Then powerful odor eliminators and ARM & HAMMER™ Baking Soda destroy sealed-in odors on contact.
