The signs of anger in a blue cat are as follows:

1. When a blue cat is angry, it will directly attack, for example, it will reveal sharp nails or multiple combination punches from the cat.

2. They will destroy items you like and suddenly run to you and scream to vent their dissatisfaction.

3. The hot-tempered British Shorthair blue cat will hide and suddenly rush out to bite or scratch someone when you get up to take revenge on you.

4. Some cats will also make "hissing" or growling sounds to demonstrate to their owners.

5. Will play alone, ignore your presence, and ignore your calls. Will deliberately walk around you, but will not let you touch it.

6. The cat’s tail will swing rapidly from side to side and slap the ground vigorously. At the same time, the extremely angry blue cat will also have its hair explode.

7. Once angry cats, the ears on their heads may become flat or droop.
