Odour Buster™ Original is a premium, clumping cat litter made from responsibly mined, superior-quality clay and eight exclusive odour and bacteria eliminating ingredients. It was developed from a formula originally created to control odours in the toughest agricultural settings: pig and chicken farms. If the Odour Buster™ recipe can eliminate odours in chicken coops and pig pens, imagine what it can do for your cat’s litter box!
