When a cat does something it shouldn't do, it's totally useless to take it to the crime scene to preach. A cat is a healthy animal. Even if you reprimand it for what just happened, it won't understand why you reprimand it. When it performs well, it is also important to fully show the field.
Patience education. I don't mean that criticism can be allowed today, but that we should criticize patiently with the same attitude at all times. If people give up halfway, their previous efforts will be in vain. "You will forgive me soon anyway." In this way, the cat will get carried away
When it is done well, praise it greatly. Although the cat can't understand the master's words, it knows the difference between the voice of reprimand and the voice of praise. When the cat is praised, its mood will also get better, so the effect of education will gradually increase. Of course, in this case, it is important to praise on the spot rather than afterwards.
