Cats' skin is extremely sensitive and covered with nerve endings. Whether it is a metal cat hair brush or a hard plastic cat comb, it is easy to generate static electricity in a dry environment. This static electricity will put the cat into a state of alertness.
If you are too busy at work and don’t have time to brush it, its hair will become tangled, making it more troublesome to comb. The severe pain of pulling will make them remember that the comb is a harmful tool. A painful experience that they will forever fear.
Cats are extremely independent predators, and they have a high desire to control their own bodies. If they are groomed forcefully, it may be interpreted as provocation, and if they feel imprisoned, their fight or flight instinct will be triggered.
The cat's abdomen is wrapped with important organs. If the comb is close to these areas, the cat will behave aggressively by gasping, scratching, and biting out of self-protection.
