What does it mean that the cat's back is arched?

The first possibility is physiological. When a cat is frightened or threatened, it will bow its back to make defensive and offensive gestures to protect itself. The second possibility is that the cat's arch back is caused by calcium deficiency. The owner can see that the cat has been arching its back. In this case, the owner can give the cat calcium tablets to improve.

Cats hunch their backs and erect their tails at the same time, which may be caused by the following reasons: cats are in a nervous and scared mood; I'm not familiar with my surroundings. If the cat shows the above actions and wags its tail slowly, the cat may be in a relatively relaxed state. If the cat is nervous, it is suggested to give the cat something familiar to calm the cat down.
