Odour Buster™ Original is a premium clumping cat litter made with responsibly sourced premium clay and eight proprietary odour and bacteria-eliminating ingredients. It was developed from a formula originally created to control odours in the harshest agricultural environments: hog and chicken farms. If Odour Buster™ can eliminate odours in chicken coops and hog pens, imagine what it can do for your cat’s litter box!
