Cats judge their ability to enter small spaces through their beards, and in fact, every beard of a cat is filled with nerves that sense wind direction and space through it. So the cats beard is very important. Why do cats have beards? Beards are very sensitive hair follicles that are connected to the muscles and nervous system of cats. In fact, every beard is filled with nerves. Beards can detect changes in airflow, helping cats detect danger, which was very useful for their ancestors. If their whiskers are trimmed, cats may lose their direction or even their sense of balance. Even touching a cats beard can be painful for your cat. 

 What is the function of a cats beard? 1. Navigation function: A cats beard is thicker than any other hair on its body, and its roots are said to penetrate deep into the skin and be filled with nerve endings. Therefore, a cats beard has the function of a tactile sensor. 2. To protect their eyes, their beards are not just on their mouths, they also have them above their eyes. Moreover, these beards growing on top of the eyes also provide some protection for cats during hunting. 3. Judging mood: When a cat is relatively relaxed, its whiskers are a natural place to relax. A slight downward curve and upward curling of the whiskers indicate that the cat is angry or feels that something dangerous is approaching, which is a sense of vigilance.
