The reasons why British shorthair cats scratch things:

1. When cats feel bored, they will scratch things to release their energy.
2. When a cat is in a bad mood, feels anxious or nervous, he will also vent his emotions by scratching things.

3. When a cat’s nails are too long, it will scratch at one place to polish its claws. The owner can prepare a scratching board for the cat.
4. When the owner does something that makes the cat unhappy, the cat may scratch around the house out of revenge. The owner must calm the cat's emotions in time.
5. Cats scratching may also be marking their territory, occupying their territory, and letting other cats know that this is their territory.
