Naturally 4 Paws is proud to carry FelinePine in Silverdale, Washington. We believe in sustainability. So no new trees are cut down in the production of our litter. Instead, we use kiln-dried shavings reclaimed from lumber production. Product stewardship and sustainable development go hand-in-hand. Our goal is to provide high quality products that offer powerful performance, while conducting our operations in a sustainable and responsible manner.
