Along with intent, cats' ears can convey emotion. The ears point forward, showing interest. In general, the greater the cat's arousal or discomfort, the more its ears rotate sideways and backward.
Your cat will most likely hiss or swat at you if it feels threatened or doesn't like what you're doing.
Cats communicate by moving their eyelids, which indicate whether they are open or closed, and by dilatation of the pupil (black portion of the eye).
When arousal occurs suddenly, whether from fear, interest, or another powerful emotion, the pupil dilates (enlarges). Wide-open eyes convey trust, while slit-like eyes might convey fear or hostility.
The cat tail conveys a variety of emotions, including arousal, affection, and attention. Both the velocity and the height of the tail have significance. When approached, cats often hold their tails up as an indication that they are open to conversation.
Typically, a flailing or thudding tail is a warning to keep your distance. A cat's tail waving back and forth could be an indication of play or frustration.
The fur of a calm, healthy cat is soft against the body. Given that cats groom themselves, you may learn a lot about the health of the animal from the condition of its fur.
Unkempt fur can be a sign of illness and should not be disregarded, especially if it is present along with other symptoms like lethargy or vomiting.
The scent signals that cats employ to communicate are not always detectable or understandable to humans.
However, cats also use body rubbing behaviour, intense urine and faeces marking, and scratching to leave scented messages that other cats can interpret.
The cat's overall body language conveys a variety of emotions, including submission, fear, and confidence.
The body language must be interpreted in conjunction with what the eyes, ears, tail, fur, and vocalisations are trying to convey.
