Primates

Eye Contact: Many primates, including humans, use eye contact as a crucial part of social interaction. For example, eye contact can convey dominance, aggression, submission, or interest. Gaze Following: Primates, such as chimpanzees and bonobos, will follow the gaze of another to understand where they are looking, which can convey important information about their environment or social interactions.

Cats

Blinking: Cats often use slow blinking to communicate trust and affection. A slow blink from a cat is sometimes referred to as a "cat kiss" and is a sign that the cat feels safe and comfortable. Eye Shape: Changes in eye shape and pupil dilation can indicate a cat's mood. Wide, dilated pupils might show excitement or fear, while narrow pupils can indicate aggression.
