The meaning of a cat’s eyes becoming round:

1. A cat’s eyes become round when it sees something it likes or has a strong interest in something.

2. When cats are active at night, their pupils will also become round in order to absorb more light.

3. When the pupils suddenly become larger and rounder, it means that the cat has entered a "hunting state" and may attack in the next second. At this time, the owner needs to be more careful.

4. When a cat is frightened, its eyes will become very round.

Note: If the cat’s pupils are always round, it is recommended to take it to the pet hospital for examination.
