While all of Naturally Freshs walnut shell formulas spark a cats wiring to bury their business in nature, our non-clumping pellet litter isnt just for cat kids. This formula is ideal for all small animals, such as gerbils, rabbits, ferrets, and puppies. Naturally Fresh Pellet Litter is made with a proprietary blend of the fibrous materials found only in walnut shells. This litter provides superior odor control, absorbs three times better than clay litter, and is virtually dust-free. Ideal for pet parents looking for a non-clay litter at a great price, our non-clumping pellet formula controls up to 7x more odor than other leading non-clumping litters.
