Cat's Best Sensitive is a completely organic clumping cat litter made from natural wood fibres. Additionally, it's super fine granules result in tight clumps with the litter itself soft on paws for fussy cats. It has superior odour binding properties formed by the natural capillary system of plants making it super effective at trapping unpleasant smells. Additionally, it can absorb up to 8 x its' own volume. Resulting clumps make waste easy to remove allowing the base contents to be left in the litter tray for up to 7 weeks. Compostable, 100% biodegradable and creating significantly less waste, it's the litter in harmony with nature.
