Pet's Pick Uber paper bedding is the ultimate lightweight, soft, dust-free bedding for small pets. We use only virgin, food-grade paper fibers in our bedding. This food-grade paper is super-absorbent (6 times its weight) and dust free. Independent tests show Uber to be 99.9% dust-free to maintain a clean space and protect your pet's habitat. You and your pet deserve a clean, fresh-smelling home. Uber offers a 14-day odor control which lasts longer than any other type of bedding. But don't forget to change your pet's bedding at least once a week. Even if it doesn't bother your nose, your small pet might feel differently.
