When cats slow blink, it is often interpreted as a sign of trust and affection. In feline body language, slow blinking is a way for a cat to show that they feel comfortable and relaxed around the person or animal they are slow blinking at. It is sometimes referred to as “kitty kisses” and is seen as a friendly gesture. Slow blinking can also be a way for cats to show that they are not feeling threatened or aggressive, and that they are open to socializing. Cats may slow blink at their owners, other cats, or even at dogs or other animals.
