Cats begin to be sensible and gentle at 10 months after birth. Cats of this size are about to become adults and can understand and complete their owner's words and commands, so they will be quieter and more sensible than when they were young. If the owner wants the cat to be gentle and obedient, he can conduct simple training at 5-8 months, allowing the cat to make corresponding actions according to the instructions, and help the cat develop good habits.
