If the cat scratches the door every night, you can severely reprimand it at a special time. If it still scratches the door, you can also lock it in a cage; but if the cat is not used to sleeping in the cage, it may keep barking. , it takes a while for the cat to get used to it before it will get better.
Tips:
Cats usually scratch at the door because they miss their owner or are energetic, so it is best to let the cat sleep less during the day , especially at night, play with the cat for a while before going to bed.
