Odour Buster Clumping Cat Litter is a clay based premium clumping cat litter ideal for single or multi-cat homes. Unlike most leading brands, Odour Buster was originally created for the agricultural sector and was later redesigned for residential use. This unique adaptation resulted in a powerful, dust free odour control solution that lasts for up to 7 days! Odour Buster cat litter is an ultra premium cat litter brand. It uniquely controls odours in a way most other brands cannot.
