What does it mean when a cat vibrates its tail? - in detail

When a cat vibrates its tail, it is typically a sign of excitement or anticipation. This behavior is often seen when cats are about to be fed, played with, or given attention. The tail vibrations can also indicate that the cat is in a heightened state of alertness and may be ready to pounce on a toy or chase after something. In some cases, tail vibrations might be a sign of stress or anxiety, especially if accompanied by other body language cues such as flattened ears or dilated pupils. However, when seen in isolation, tail vibrations are usually a positive indication of the cat's emotional state. It is important to observe the entire body language and context to fully understand what the cat is trying to communicate.
