Cats use their tails to communicate their emotions and intentions to other cats and humans. A cat's tail movements and positions can indicate its mood and level of alertness. For example, a relaxed cat may have its tail in a neutral position, while an angry or fearful cat may have its tail held high. A playful cat may have its tail held up and twitching, while a content cat may have its tail wrapped around its body. Cats also use their tails to express their feelings of affection by wrapping their tails around their owners.
