Thanks to its unique technology, our OdourLock litter neutralizes ammonia formation for unrivalled control of urine and faeces odours. Cat urine does not contain ammonia per se. Rather, this gas is formed in the litter tray, when urine comes into contact with oxygen and encourages the growth of bacteria. Ammonia is responsible for the unpleasant odor emanating from the litter box. Our technology activates on contact with urine and neutralizes odors for over 40 days. OdourLock litter is perfect in a multi-cat environment, since simple daily maintenance of the trays ensures optimum cleanliness that will delight you and your cats!
