Litter made from plant sources like pine, wheat, corn, or paper is appealing to environmentally-minded owners. Unlike clay-based litters, which are strip mined, biodegradable litters generally take leftover materials like sawdust, and put them to good use. You’ll suffer less eco-guilt when it’s time to throw them out too, since they break down more quickly than traditional litters. You can also compost the used litter, although you won’t want to use them on plants you’ll eat.
You can find both clumping and non-clumping varieties of biodegradable litter, and they offer average to good odor control.
