Cats slow-blink at humans as a sign of trust, often called a "cat kiss."

 

 Rapid tail twitching during play warns of overstimulation and a need for space.

A question mark tail (curved tip) signals a cat’s curiosity and friendliness.

When a cat wraps its tail around you, it’s expressing love and ownership.

An exposed belly is usually a defensive posture, not an invitation for a tummy rub.
