A significant portion of the content of our paper cat litter comes from post-consumer waste derived from newspapers. When newspapers aren't recycled, they are either dumped into landfills or incinerated. We encourage everyone to recycle their discarded newspapers, and buy products from companies that use recycled materials.
Concerned about the inks? Don't be. Today, most publishers print using harmless organic inks and/or soy-based inks. The process used to make Yesterday's News neutralizes these inks so there will be no residue left on your cat's paws or fur.
