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.
A pregnant kitty will carry her litter of kittens for around nine weeks before giving birth to them. During the pregnancy and while nursing, she'll need extra care, veterinary checkups, love and nutrition to keep her safe, snug and healthy.
