Paper cats litter is basically made of post-consumer recycled paper. As early as 1947 when Ed Lowe invented the kitty litter, manufacturers have also begun reinventing the product to produce an eco-friendly version in the form of paper litter.
The most common material used in paper cats litter are pieces of post-consumer newspaper. They’re re-pulped, de-inked, and screened so that the resulting litter would no longer retain harmful chemicals.
