High-heat treated pine pellets absorb odors and liquids by forming soft clumps from the bottom of the pan up, leaving a dry surface for the cat. Pellets are perfectly sized for the comfort of the cat and for the cleanliness of the home. They won’t stick between a cat’s toes, and don’t track. Made of reclaimed pine wood from sustainable forestry products, in a zero-waste production facility. 100% renewable, 100% biodegradable. Perfect for multiple cat households.
