The functions of cats’ whiskers:

1. Can judge the width of the passage. Cat's whiskers have the function of assisting judgment and can help cats judge the width of the passage. A cat's whiskers grow next to the mouth, and the width of the cat's whiskers is the same as the width of the cat's body.

2. Determine the location of the perceived target. Cats' whiskers have a strong sense of touch, so they can sense changes in the surrounding airflow and the humidity of the air. Once the whiskers come into contact with something, the cat will know the general structure of the surrounding area, so the cat can easily approach the target object.

3. Mood signals. A cat’s whiskers are also an important symbol of expressing its mood. For example, if a cat’s whiskers hang loosely on both sides and look very leisurely, then the cat must be in a good mood at this time. If a cat is angry or frightened by something, the whiskers will stick to its face.

Notes on cat whiskers:

1. Cats don’t like things stuck to their whiskers. So try to choose a larger water basin when taking a bath, and don't let water get on the cat's whiskers.

2. Never trim a cat’s whiskers. It is normal for a cat’s whiskers to fall off naturally. If your cat's beard is cut off, it will also have some impact on the cat's normal life.

3. Repeatedly cutting off a cat’s beard will have a considerable psychological impact on the cat’s heart.
