OdourLock is the perfect litter for a multi-cat environment. Thanks to its unique technology, it neutralizes ammonia formation and provides unrivaled control of unpleasant odors. Ammonia is formed in the litter tray when urine comes into contact with oxygen, promoting the growth of bacteria. It is this gas that is responsible for the unpleasant odours coming from the litter tray. Our technology activates on contact with urine and neutralizes odors. Simple daily maintenance of the tray ensures optimum cleanliness.
