Results: Why do cats wag their tails?

What does it mean when a cat wags its tail? A flicking tail or side-to-side swish indicates excitement, contemplation, beginning irritation, or that your cat is in pain. This could also mean your cat is focused, such as when watching a bird. When cats say hello, the tail is often extended high into the air and sways back and forth. If they're greeting another cat, this wag can be accompanied by mutual head rubbing. Are cats happy when they swish their tail? Cats wag their tails when they're happy and confident. A playful swishing tail will usually accompany your cat's signature playtime behavior. Cats use their tail movements, along with their eyes, ears, and body postures, to communicate.
