A cat's beard will not grow back if half of it is cut off. The cat's beard will only grow back after it falls off naturally. If the cat's beard is cut off, it will cause balance imbalance and "hit the wall". Cat's whiskers are a special sensory organ of cats. There are very fine nerves at the root of the cat's whiskers, which can sense the slightest touch of an object. Once the whiskers are cut off, the cat will seem to lose its sense of direction. At least it will not dare to run fast, and at worst, the cat will lose its balance.

The functions of cat beards:

1. Cat beards can be used to modify the cat’s facial shape and increase facial beauty.

2. Cats’ beards don’t just grow on their faces, but also above their eyes and on their limbs. The beard above the eyes can play a good role in protecting the eyes.

3. Cats’ whiskers can keep them alert to their surrounding environment and what is happening around them.

4. Cat whiskers are equivalent to tactile sensors, which can be used to help measure changes in external airflow, allowing cats to avoid obstacles even in dark environments or unfamiliar environments.
