Cature Smart Pellets are made of natural woods. These pallets do not stick to the paw's body, stay in the tray. The micro-fine fibrils trap the liquid inside the natural organic fibers. In only 10 seconds, the litter can absorb all the liquid and lock odor super effectively. Sustainable Biodegradable Flushable Naturally anti-bacterial Super Odor Control: Control odor for up to 7 days without scooping. Quantity: 7.6 Kg.
