Methods to prevent cats from scratching:

1. Cats may need to polish their claws when scratching. You can prepare a scratching board for the cat so that it has a place to scratch. Sharpen your claws so you won't grab things randomly.
2. Spray lemon water on the furniture that the cat likes to scratch. The cat will hate the smell and will not scratch it again.

3. When a cat scratches something randomly, stop it in time and scold it loudly so that it will not dare to scratch again in the future.
4. When the cat scratches randomly, the owner can spray water on it. The cat does not like the feeling of being sprayed with water. After a few times, the cat will not dare to scratch it again.
5. Trim your cat's nails regularly. It will be very painful to scratch things without nails, and the cat will stop scratching randomly.
