Purring: Indicates a good mood and a sense of comfort. Signs of anger or caution: Tail wagging quickly and forcefully: A sign of irritation or being in a bad mood. Note that this is the opposite of a dog's behavior. Ears flattened backward (airplane ears): Indicates fear, discomfort, or vigilance. Hissing: An expression of strong intimidation or anger. Signs of anxiety or fear: Pupils dilated: Indicates surprise, fear, or a state of high tension. Crouching or shrinking the body: A defensive posture taken when feeling threatened. Cats are animals that express their feelings through their bodies, and their gestures and actions carry various meanings. A cat's emotions can be read from different parts of the body, such as the eyes, ears, tail, whiskers, and overall posture. When they feel safe, affectionate, sleepy, or comfortable, they will purr. Generally, a low-pitched voice represents intimidation, caution, or anxiety. Conversely, a high-pitched voice represents a request, affection, or a distress signal. While cats are often thought to be cool and detached, they are actually animals with very rich emotional expressions. Although they cannot speak human language, they try to convey their feelings to their owners through actions and reactions. The act of a cat slowly blinking repeatedly represents trust and affection toward a human. By blinking slowly, they send a signal to their owner that they are in a state of comfort and peace. On the other hand, when a cat moves its tail so fast you can almost hear a 'whoosh' sound, it may be in a bad mood or has found something to 'fight.' You should not force contact at such times.
