Cattail language: what your cat's tail tells you

Why do cats wag their tails?
Cats move their tails to express their feelings. So what does it mean when a cat wags its tail in particular?
Tail movement in the form of quick strokes
Recommend
When your cat moves her tail in quick flicks or slaps it against the ground, she is irritated, annoyed, or angry. This behavior signals that something is bothering her.
This behavior is a warning sign. In other words, if you are petting your cat and her tail begins to flick quickly, she is asking you to stop. If you continue, those quick movements can be a prelude to growling, hissing, swatting, or biting.
Tail swing
When your cat slowly moves her tail from side to side, it can mean she is intensely focused on something—perhaps a toy, another animal in the house, or something outside. The cat may be preparing to attack and pounce.
Engaging in predator-like behaviors such as stalking and pouncing is good enrichment for your cat, so let her follow whatever captures her attention.
Tail twitching
Your cat may twitch her tail when she is especially excited to see you or another cat. Sometimes, if a cat's tail trembles when you lift it straight and support it against a vertical surface, it can signal urination.
What does it mean when a cat's tail stands up straight?
When a cat's tail is held upright, it means she feels socially confident and is approaching in a friendly way.
This tail posture is a friendly greeting between cats; kittens greet their mothers this way. A 1997 study by Cameron-Beaumont found that cats were likely to approach a cat-shaped silhouette if its tail was raised, but were reluctant to approach when the tail was low.
If your cat approaches you with her tail raised, it is a good time to pet or play with her.
What does it mean when the tail takes the shape of a question mark or a hook?
You may notice your cat's tail sometimes curling like a question mark—upright but with a twist at the tip. This tail position means your cat is happy and approaching in a friendly way.
Seeing your cat's tail in this pose is an invitation to interact. While it may be tempting to stroke the curled tip, most cats prefer being petted around the facial glands on their cheeks, under their chins, and next to their ears.
Why do cats fluff their tails?
If your cat puffs up her tail and arches her back—perfect Halloween-cat posture—it means she is startled or frightened by a sudden, serious threat.
Her fur may stand on end (piloerection) to make her look larger. This is a defensive reaction that signals she wants to be left alone.
This tail position is often triggered by a perceived threat: other animals in the yard, approaching dogs, visitors in the house, or sudden noises. Remove the trigger to reduce her stress. If you try to interact with a cat whose fur is standing on end, your approach may be seen as a threat and could provoke aggression.
What if your cat's tail is low toward the floor?
A cat may lower her tail below the level of her back if she is frightened or anxious. If your cat tucks her tail between her legs, she is already scared or may be in pain.
Why do cats wrap their tails around their bodies?
If your cat is sitting or lying down with her tail wrapped around her body, it means she is uneasy, on the defensive, in pain, or feeling unwell. When you see this, stop interacting with your cat and make sure the surrounding conditions are free of stressors.
If your cat frequently crouches with her tail tightly wrapped around her body for more than a few days, she should be evaluated by a veterinarian to rule out pain or illness.
Although fully understanding your cat's emotional state requires looking at more than just tail movements, the tail is often the most expressive part of a cat's body language. Understanding your cat's body language better will improve your relationship with her.
