First of all, when the cat has a tendency to go to the sofa or bed, the owner should stop it and let it know that this is not allowed; secondly, the owner can buy a comfortable cat nest for the cat and place it in a suitable place. The location allows the cat to get used to sleeping in the cat nest; again, the owner can close the bedroom door and spray citrus or lemon-flavored water on the sofa. ​​​​​​​ Cats can't stand citrus and lemon-flavored things, so they will avoid these things, so owners don't have to worry about cats getting on the bed or table. You can place grapefruit peels on the table to avoid cats. Generally, owners need to train their cats from an early age so that they will not develop the habit of going to sofas and beds.
