I don't know if this is technically a green product, but I'll tell you why I think it is. I use "World's Best Cat Litter" for my 3 cats. We even had 5 at one time. I consider it to be environmentally because it is made from all natural whole-kernel corn, is earth-friendly and biodegradable.. It is not harmful to my pets or the environment, but mainly because I use much less of it than other litters. No dust like clay litter and no perfumes or chemicals like other scooping litters.
