First of all, we owners can use a comb to comb the hair of our cats, and the hair that cannot be combed can be cut off. We breeders must always maintain regular combing and bathing of our cats. Secondly, our cats are infected with bacteria and fungi, causing secretions to trap the hair. We can also use a warm towel to clean the hair. If we clean our cats regularly, they will be fine.

There are two common reasons for cat hair bumps:

1. The dead hair on the cat’s surface will fall off and be combed or licked off by the cat. New hair grows entangled with dead hair, plus static electricity, oil on the skin surface, and some thick substances attached to the body surface, all of which can easily cause hair to tangle together.

2. Cat’s daily activities will cause the hair to rub and become tangled. If you don't comb it in time, it will get knotted. This is why hair knots often appear under the belly, at the base of the front and hind legs, or under the tail.
