The rounding of a cat’s eyes mainly means three things: emotional changes, self-protection, and entering a hunting state, which are all normal phenomena. During daily feeding, a cat's pupils usually look like a line during the day and become round at night, so don't worry too much. However, if the owner finds that the cat’s pupils have always been round, the cat is probably sick. At this time, it is recommended to take the cat to the pet hospital for examination in time to see what is the specific cause, and then take targeted treatment measures.

1. Emotional changes

When a cat sees something it likes, has a strong interest in something, or is frightened and feels scared, it will cause sympathy due to changes in emotion. Nervous excitement can also cause the cat's pupils to become enlarged and the eyes to become round.

2. Self-protection

The rounding of the cat’s eyes we see is actually an illusion of the cat’s pupils becoming enlarged. When the light dims, the cat will pass through Protect your eyes by dilating your pupils. At the same time, when the light is relatively dark at night, cats will enlarge their pupils to absorb more light because they need to see things clearly, so their eyes will also become very round.

3. Entering the hunting state

When a cat enters the "hunting state", its eyes also focus on the prey, so the pupils will suddenly become larger and rounder. This also means that the cat may attack in the next second, so the owner needs to be more careful at this time and it is best not to approach the cat easily.
