What Is Kitty Litter Made Of? Before 1950, kitty litter mostly consisted of sand, dirt or ashes. The first modern kitty litter was created when a neighbor of entrepreneur Edward Lowe asked him for sand for her litter box. Mr. Lowe, whose business created absorbents, convinced his friend to use clay rather than sand.
Walnut-based cat litter is made from the shells of walnuts, a product that would normally go to waste. The leading brand of walnut litter is BLUE Naturally Fresh. Itâs not covered in the ConsumerSearch report, but itâs the top-selling natural litter at PetSmart, and itâs also the brand my husband and I use now.
