J-B Pet Supplies is proud to carry Naturally Fresh in Hawthorne, New Jersey. This biodegradable litter is made from 100% natural walnut shell. That’s as natural as it gets without turning your place into a jungle. It stamps out odor and absorbs three times better than clay litter. That works for both of you. With low dust and low tracking, things stay clean while your wild child does what makes her DNA happy. Because when she's happy, you're happy.
