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.
The type of litter you put in your catâs litter box will have a great influence on whether he successfully chooses that location for elimination or whether he ends up peeing on your carpet. Litter scent (or lack of), texture, cleanliness and depth all play a factor in litter box appeal.
