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.
Cat Litter Boxes. Litter boxes are a big part of your catâs daily routine â and yours â so itâs important to find one that suits you both. Consider the size and location of the box and whether your kitty prefers a hooded or open litter pan. Youâll find everything from basic, rectangular litter boxes in every size to those with hoods, steps and flaps.
