The reasons why cats always scratch people:
1. When the owner plays with the cat and teases it with his hands, the cat will get used to scratching the owner's hand.
2. If the owner beats and scolds the cat and the cat is frightened, it may fight back and catch the owner.
3. Cats have hunting habits and may use their walking feet as prey.
4. If the owner always touches the cat’s sensitive parts and makes it feel uncomfortable, it will scratch.
5. If the cat is eating and the owner is teasing it or moving its food bowl, it will think that the cat is robbing its food and will attack.
