A cat's body is covered with approximately 130,000 pieces of hair per each square inch.
- Coarse, straight, thick guard hairs that narrow to a thin tip insulate a cat’s body, protect the skin and help their sense of touch.
- Medium-sized awn hairs also insulate and protect a cat’s body, yet they’re skinnier than the guard hairs.
- The secondary hairs are stationed in the undercoat. These crimped or rippled-appearing hairs are the skinniest in a cat’s coat. They help adjust body temperature and prevent too much loss of body heat. Secondary hairs are more plentiful than guard and awn hairs.
