Thanks to its unique technology, our OdourLock® litter neutralizes ammonia formation for unparalleled urine and feces control. Ammonia forms in the litter box when urine comes into contact with oxygen and bacteria grow, creating an unpleasant odor. OdourLock® technology activates upon contact with urine to neutralize odors for over 40* days. Comforting and reminiscent of the neutral scent of talcum powder, the talcum powder fragrance will leave a clean scent around the litter box. Our goal is not to perfume your home, but to respect the health and sensitivities of cats. Our fragrances are chosen to be attractive to cats and are activated only upon contact with moisture. Thanks to our cutting-edge manufacturing processes, we can offer you a dust-free litter, ideal for cats and preferred by owners of cats with asthma or dust allergies. Its clay-based formula is almost as soft as sand and leaves no residue. Pour 10-12 cm of litter into an empty, dry litter tray. Remove solid waste daily with a perforated scoop; do not flush. Be sure to wash your hands thoroughly after each use. After about a month of use, or after 40 days for our OdourLock® litter, empty the entire litter box into a garbage bag and clean the tray.
