Video: Cat Fur
The wild cat has four types of hair: undercoat, guard, protective and tactile hairs. Each square millimeter of skin can have up to two hundred hairs - as a result, the cat has become the owner of a luxurious fur coat.
The undercoat is the hair closest to the surface of the skin, and its main purpose is to keep the animal warm and maintain the same body temperature. It is the shortest, thinnest and softest hair. Their diameter is approximately the same along their entire length, they are very wavy, and when examined under a magnifying glass, they give the impression of being curled or well-groomed. It is these short and wavy hairs that give the undercoat its excellent thermal insulation properties.
The guard hairs form the so-called medium coat. They are intermediate between the soft undercoat and the protective coat on the top of the cat's fur. This hair is coarse, one might even say spiky, with small bulges closer to the ends, before tapering at the very tip. Their purpose is partly isolation, partly protection.
Tactile hair - Large, coarse hair that acts as a sense of touch. This special tactile hair forms a mustache on the upper lip; in addition, they are found on the cheeks and chin, around the eyes and on the ankles of the forepaws. Compared to other hair types, these hairs are very few in number, but play an essential role when the cat is moving in poor light or hunting.

Among all three types of wool, the most abundant is the hair of the undercoat. For every thousand hairs of the lower wool, there are about three hundred guard and about twenty protective ones. But these proportions vary greatly depending on the breed of cats, especially when it comes to purebred animals. This is because they were carefully selected according to the criteria of wool, to which special requirements were imposed in each case. In some breeds the coat is thin, in some it is short and coarse or long and fluffy. The differences are due to the predominance of certain types of wool and, accordingly, hair.
Thus, selective breeding of the breeds played a cruel joke with the natural fur of cats, producing such types of this animal that would never survive in the wild. However, fortunately for these purebred animals, usually there are always enough human slaves at the service who will fulfill all their whims, will look after them and cherish them, but, undoubtedly, if they were presented to themselves - inevitable vagrancy would be the best way out for such animals. and change would be so inevitable. They would suffer from the climatic absurdities of our planet, but if they managed to survive and enter into mixed marriages, then after a few generations their descendants would return to the “wild” version of wool.
