A cat's pupil constriction means that the light is strong, which is a physiological reaction when exposed to sunlight. The owner does not need to worry too much. Secondly, if the cat also arches its body, has hair all over its body, and makes a shrill cry, the pupil shrinkage also means that the cat is angry. At this time, the owner is advised to stay away from it as much as possible, otherwise it is likely to be accidentally injured by the cat. . In addition, a cat's pupils may shrink because the cat has entered a hunting state, and the cat will narrow its pupils to locate its prey.

1. Strong light

The function of a cat’s pupil is to control the amount of light entering the eye from the outside world. When the ambient light is relatively strong, the cat’s pupil will shrink in order to control the amount of light entering. On the contrary, when the ambient light is weak, the cat's pupils will dilate. As long as the cat has no other abnormalities, pupil constriction is generally a normal physiological phenomenon, and the owner only needs to dim the light.

2. Angry

If the cat’s pupils are constricted, its body is arched, its hair is exploding, and it makes a sharp cry, then the cat may be angry. Especially its vision will become sharp at this time. At this time, the owner should pay attention and never provoke the cat, because the cat will be very aggressive at this time. If it is provoked, it is likely to be scratched by the cat.

3. Entering the hunting state

Cats will also narrow their pupils when locking prey, so if you find that the cat is always staring at one place at this time, it may be that the cat has entered In hunting mode. At this time, the owner must stop teasing the cat with his hands, otherwise the cat is likely to regard the owner's hands as prey targets.
