Training methods for kittens that are too naughty:

1. If a kitten is too naughty, you can put it in a cage appropriately as a punishment to improve it.

2. When the kitten is very naughty, you can pat its back or ears appropriately to let it know that its behavior is wrong.

3. You can also reward the kitten with snacks at the moment or time period when it is very good, so that it can improve its usual naughty behavior.

4. It can also be improved by training it to play with toys on its own to distract its attention.

Reasons for kittens being too naughty:

1. Sometimes the kitten may be left alone for too long, causing its mood to fluctuate and become naughty.

2. It may also be because the kitten is in estrus and will be very naughty due to endocrine hormones.

3. It is also possible that some cats are naturally very naughty and lively.
