First, scold loudly.
Although cats can't understand human language, scolding cats is really a way to make them realize their mistakes. This is because when the owner scolds the cat, the cat will be scared by the owner's voice, tone and mood, so as to understand that his behavior will make the owner angry. Especially when the cat is caught red-handed, the reprimand of the owner often makes the cat realize what to do and what not to do. Therefore, when a cat makes a mistake, the owner can let it know that he has made a mistake by yelling loudly.
Second, clap.
If yelling is just a verbal lesson to the cat when it makes a mistake, slapping the cat is telling the cat that it has done something wrong. This method is effective to some extent. After all, cats will subconsciously make evasive actions, such as dodging and running away, when they see their owners trying to hit themselves. Once this kind of thing is repeated many times, the cat will remember why it caused the owner's unhappiness, thus reducing the possibility of making mistakes.
Third, turn it off.
When a cat makes a mistake, being locked in a small room for a while will make the cat very uneasy. In this uneasy mood, the cat will realize that some of its actions have upset its owner, and thus realize its mistakes. It can be said that confinement is a very effective punishment for cats, which can make cats quickly realize their mistakes and correct them. However, this method cannot be used in many cases, and it is best to use it when the cat makes a very big mistake. After all, if the cat is confined more, it may get used to it, which may cause it to be unaware of its mistakes, or make the cat have rebellious psychology, thus aggravating the mistakes.
To sum up, if cats want to realize their mistakes, they can yell, fan or turn them off loudly when they make mistakes.
