Odour control and Lightweight Convenience. This Triple Action formula uses baking soda to neutralise urine odours and is made from bentonite and cellulose which locks in ammonia odours. This natural litter forms an easy-to-clean one scoop clump. Its innovative lightweight formulation reduces the average bag weight of up to 35% than traditional clumping litter, making it much easier to carry around and refill the litter tray.
