Cats can’t speak because if they could, they’d likely bark out an endless number of orders, commanding their humans to submit to their will.

A stretched tail denotes aggressiveness. A tail stretched with a hook up is usually a greeting. However, a tail stretched with a hook facing down is a defensive attitude. Unfortunately, this veterinarian neglected to determine what it means when your cat slaps you in the face with its tail.
