The “slow blink” is a distinct, non-verbal gesture in the feline world, often observed by cat owners. Visually, the behavior involves the cat slowly closing its eyes, holding them partially or fully shut for a moment, and then deliberately opening them again. This action is often interpreted as a unique form of feline communication, sometimes affectionately referred to as a “cat kiss.”
Decoding the Slow Blink
The meaning of the slow blink is rooted in the fundamental differences between aggressive and non-aggressive body language in the animal kingdom. In many species, including cats, direct, sustained eye contact is considered a challenge or a threat. A hard, unblinking stare signals hostility and can precede a confrontation.
By contrast, closing the eyes, even for a brief moment, is an act of vulnerability that signals the absence of aggressive intent. The cat is momentarily dropping its guard, which communicates to the other party that it feels secure. This gesture is a strong indication of a relaxed state, allowing the cat to express deep trust in its immediate surroundings and companions.
This behavior is an affiliative signal, meaning it is used to establish and maintain a friendly social bond. When a cat offers a slow blink, it is communicating that it feels completely at ease in your presence and perceives you as a non-threat. The slow blink signals a positive emotional state and a desire for peaceful coexistence.
Using the Slow Blink to Communicate
Humans can intentionally use the slow blink to engage positively with a cat, mimicking their non-aggressive communication style. To initiate this interaction, first ensure the cat is in a relaxed state and is looking in your direction. Once you have their attention, narrow your eyes gently as you would in a relaxed smile, then slowly close them for about one to two seconds before slowly opening them again.
This soft closing of the eyes functions as a reciprocal affirmation of the bond you share. By repeating the cat’s own signal, you are effectively “speaking their language” and reinforcing the message that you are calm and trustworthy. The timing and context are important, as this gesture is most effective when the cat is resting or quiet, rather than when it is excited or engaged in play.
Validating the Behavior Through Research
Behavioral studies have provided experimental validation for the slow blink as a form of positive interaction between cats and humans. Experiments often involve comparing a cat’s reaction to a human who initiates a slow blink sequence versus one who maintains a neutral, unblinking expression. The findings consistently confirm that this gesture increases positive emotional states and approach behavior in felines.
In one study, cats were observed to be significantly more likely to perform a slow blink back at a human who had first slow-blinked at them. Furthermore, when an unfamiliar person used the slow blink technique, cats were found to be more willing to approach that individual. This measurable response provides evidence that the slow blink acts as an intentional signal, leading to increased positive social interaction and reduced apprehension in cats.
