Mustache has mustache. A cat is not a cat without a mustache. But, admiring the luxurious mustache of our pet, we do not always understand how important they are for him. Not only for beauty, of course, but for everyday life. After all, the mustache, or, correctly, vibrissae, is an organ of touch, at least an important part of this organ. They inform the animal about direct contact with objects located very close.

And these items include not only chairs, not only bowls, pans, in contact with which the cat is especially interested, but also the hands of the owners (and not the owners too), mice, birds and other prey, and, finally, dogs with whom to cats in most cases, tensions. During the time of love, touch helps to establish and establish relationships between partners, and at a tender age - kittens communicate with their mother, and mother - with them. In a word, whiskers-whiskers with the help of direct touch inform about objects located from the cat at a distance of the length of the whiskers.

Of course, a cat can get information about these objects by directly touching them with fur or skin, but it is more profitable for her to come into contact with these objects a little earlier, it is clear that in this case, having touched the whiskers ahead of time to her prey, she will know about it in advance and at least not much, but still be able to make a decision earlier. When she slightly outstrips, for example, a fleeing mouse, then it is these “slightly” that will bring her success.

Whiskers are of great benefit to a cat in many other life situations, for example, when she crawls into a narrow gap and is not very sure that this gap is available to her. Whiskers are invaluable to wild cats when sneaking up on prey, when cats are forced to wade through dense bushes or difficult thickets.

What are the whiskers-whiskers that give the cat such a unique appearance? These are the tactile hairs that we see on our pet's upper lip. They are long, thick, conical rods, straight or slightly curved. Special muscles provide mobility, which makes the movement of your pet's whisker a little fun. The number of whiskers on the right and left upper lip can be about 12 or more, while they are located in four horizontal rows.

The main feature of these vibrissa rods is their elasticity, which is ensured by their conical narrowing towards the end, as well as their thin structure. From above, they are covered with polyhedral or rounded cells, the edges of which are in contact with each other and together form a dense layer - the cuticle. On the contrary, the cells that make up the core are more loosely located and there are voids between them. If the reader was fond of fishing and dealt with a telescopic rod, then it is easy for him to imagine the fine structure of the tactile hair, as well as the main principles of its operation. Any vibration caused by touching the tip is immediately transmitted to the base of the rod, where your separation is.

At the base of the vibrissae of the cat there is a very interesting formation called the root, the structure of which is shown in the figure. Here, around the thickened tip of a hair that sits in the surface layer of the skin, there is a blood lacuna and many sensitive nerve endings, the so-called pachinia bodies, and the blood lacuna is a blood bubble, which is also called a sinus. Any vibration of the hair tip is transmitted to the root, where it is perceived by sensitive nerve endings, immediately informing the brain about it.

Thus, vibrissae act as sensitive antennas that trigger a complex mechanism of excitation of nerve endings - tactile or pachinia bodies. The high sensitivity of these bodies is ensured by the use of hydraulic mechanisms. Since the base of the hair is immersed in the blood sinus, any vibrations that come here from the apex (outer hair shaft) are amplified, localized, and excite the corresponding pachinia corpuscles. Thanks to this, the tactile center of the brain receives information about in which part of the space immediately surrounding the cat, important living objects or objects are located.

However, so far we have talked about only one tactile hair-vibrissa, by the way, also called sinus, but in fact, on the body of the cat and, above all, on the head, they are located in greater numbers. In addition to the so-called whiskers, groups of such hairs, although much shorter than the whiskers, are located on the chin, above the eyes and in the cheeks. In addition, the same hairs grow on the ankles, playing an important role in hunting mobile prey. At the same time, hairs growing on other parts of the body possess sensitivity to touch, although not as perfect as that of vibrissae. For example, if you look at your pet's coat, you will easily find that individual hairs stick out from the flat surface of the fur, which also perform tactile functions. Of course, they are softer than vibrissae, and not as sensitive,but they also help the cat determine where someone is touching it.

Thus, on the body of a cat there are many sensitive "antennas" that allow it to more confidently navigate in the immediate environment, identifying dangerous or, conversely, favorable contacts for it. In contrast to further orientation, which is provided by hearing, sight or smell, touch only acts in direct contact and serves the so-called near orientation. And therefore, taking care of your pet, do not improve its appearance by cutting or, even more so, pulling out the curved vibrissae: this will greatly complicate the possibility of its orientation in the surrounding space.
