Why do cats have beards? In fact, cats’ beards are organs that help them sense their surroundings. The hairs in the beards can capture particles and odors in the air, and even sense changes in the air, so that they can respond in a timely manner.
First, a cat's beard is equivalent to a ruler, which is a tool used by cats to measure width and height when catching prey. Cats living in the external environment can measure the size of the mouse hole when catching mice.
Secondly, the beard can also be used as its sensory organ. If there is no beard, the cat's sense of balance will be greatly affected.
Third, the beard is also an external manifestation of emotional expression of cats. When it is angry and wants to attack, the beard will also show a different state.
