For example, when faced with strong light, the pupil shrinks (big eyes, small pupils); under soft lights, the pupils dilate (big eyes, big pupils); a sudden change in light intensity will also cause cats to adapt to the light through squinting, etc. At this time, the size of the eyes and pupils will change. ​​​​​​

Secondly, the cat’s energy or sleepiness can also change the size of the cat’s eyes. For example, when a cat is playing, he is more excited and his eyes widen (big eyes, big pupils); when he is sleepy, he starts to slowly squint, and finally Fully closed and asleep (facing bright light, small eyes, small pupils); this is what everyone calls a look of contempt, even though the person is just dozing off.

In addition, the different directions in which cats look at things can also make their expressions look slightly different. At the same moment, the cat is staring straight ahead with a deep and intelligent look; the next second, looking up, the whole cat is demented; therefore, cats have many different expressions, and they may be different in different situations.
