A cat’s beard will grow back even if it breaks. If a cat's beard falls off or breaks, it is part of the cat's body's normal metabolism. The cells in the hair follicles will continue to proliferate and differentiate, so the beard will continue to grow, and it will take 2-3 months to grow back. But if the hair follicles on the cat's chin are damaged, the beard will no longer grow.

Function of cat beard:

1. Beautification effect. Cat's whiskers can be used to modify the cat's facial shape and increase facial beauty.

2. Maintain body balance. Beards play a role in regulating and maintaining the cat's body balance. Balance is especially important for cats.

3. Guidance function. Sensing a change in the surrounding air flow can serve as a guide for cats to avoid collisions with obstacles.

4. Measuring tools. A cat's whiskers can be used as a ruler to measure whether the environment the cat passes through can accommodate the cat's body.

5. Protect your eyes. The whiskers that grow above the eyes also provide a certain degree of protection when cats are hunting.

6. Judge your mood. If the cat is relatively relaxed, the whiskers will have a slight drooping arc. When the whiskers turn up, it means that the cat is angry or feels that it is in danger.
