There is still the saying “eyes are the windows to the soul”, for cats, eyes have their own language to express their emotions.
Cats communicate with us through our eyes. Whatever they want to say can be understood through the position of the eyelids and the changes in the eyes. The messages range from unpredictable to recognizable. They do not have to call out to give the message, but the message will be more confirmed through other parts of the cat’s body such as tail position, ear position or through their fur.
Cat’s eyes when agitated
Any strong emotions such as fear, anger, excitement, and excitement can lead to a sudden contraction of the pupil. You may see a cat’s pupil shrink when there is food in front of it, for example a mouse. In the other case, when a new cat comes.
Cat’s eyes when showing confidence
Your cat’s eyes will open wide when awake. Keeping your eyes open to potential hazards shows your cat’s absolute confidence. For example, when a cat is rubbing your head against your cheeks or doing the same thing with a friendly dog, it is trust, even affection.
The cat’s eyes when showing its status
Their eyes will stare and not blink from a certain distance, which can be understood as a sign of control, domination, or even attack. Owners often do not recognize this behavior of cats, such behaviors are often demonstrated when they want to control the danger of being encroached on food or toys from other cat members in the house. Or simply, staring without blinking helps a cat warn other cats not to get close to its food bowl, sleeping area or territory.
Cat’s eyes when showing conflict
Tiny eyes indicate strong emotions such as fear or agitation. Shrinking the pupil also protects the eyes from the opponent’s claws. Avoid covering the eyes of an unfamiliar cat or you could be attacked by it.
Eyes show affection
When comfortable and confident, a cat often has a droopy figure, with narrow eyes. Send a kiss of the wind to your pet — look at them with affectionate eyes, and gently blink. If the cat blinks at you, then you will be deeply loved by it.
