Pestell Easy Clean Paper Cat Litter is made with recycled paper and is completely biodegradable to make this an environmentally friendly option for cat litter. It can even be composted or used as mulch in your garden! The Easy Clean Paper formula still provides you with the odor control and absorbtion of a non-clumping cat litter by using baking soda in the paper fibers. It is 99% dust free and 100% non-allergenic.
