這是貓界友善交流的一種方式，慢慢眨，或一個眼blink，不要盯著。我和我家貓經常這樣友好交流，消除矛盾！

Non-verbal communications

“Kittens and cats that stare at others of their kind do so when they are feeling threatened, aggressive or hostile. But when cats blink at each other, they are giving each other a sign that they are coming in peace and that their intentions are friendly. A one-eyed blink is considered to be akin to a handshake or a hug.”
