Eye squinting and Tail wagging.

When cats are stairing at you while squinting repeatedly, it means that they are happy with you (or trying to say they love you). When a cat wags their tail slowly, it means they are happy. But, if their tail is wagging fast back and fourth, stay away. [emoji]128077[/emoji]

Also, when a cats eyes are open wide, that means that they are frightened, or focused.
