What is the function of cat beards? This beard helps them perceive and detect their surroundings. They can help cats know their environment and can help them to better roam and crawl and avoid being caught. At the same time, the beard can also help cats sense the odor around them, thereby better hunting other animals.

The cat's beard is used as a ruler to measure the width of the road you are walking and determine whether you can pass through a certain place. In addition, when we touch the cat's beard, the cat will blink. This is because the cat's beard and eyelids are connected through the nerve structure of the reflex arc, and the cat's beard will close its eyes reflexibly when touching a foreign object.

Cat's beard is also a sensory organ called tactile hair. It can sense the difference between 0.2g of weight and 0.000005 mm, helping cats walk freely in the dark.

In fact, cats' beards not only grow on their mouths, but also have several beards hidden above the cat's eyes, on the cheeks, and on the inside of the cat's front legs.
