Educational information, not veterinary or individual behavior advice. A slow blink does not diagnose eye health or authorize touching. Do not hold, corner or provoke a cat for a response. Ask your veterinary team about health or behavior concerns.
A gentle signal, not a translation app
A cat narrows its eyes across the room. It is tempting to translate that moment into a sentence about love. The evidence supports a more careful description: slow-blink exchanges may be a form of positive communication between cats and humans. It does not give us a dictionary for every individual blink.

The rest of the scene still matters
International Cat Care explains that a slow blink can be a friendly greeting, but can also occur when a cat feels vulnerable. Keep the setting, distance and what happened afterward in view. A single facial movement should not erase the rest of the interaction.

An invitation can end without contact
Avoid staring or leaning over a cat to get a response. Give the cat room to move away. A slow blink from either of you does not require an approach, a photograph, a second attempt or a stroke. Leaving the interaction there is a valid ending.

Read, notice, then keep a question
The research guide separates results from interpretation. The observation note separates what you saw from what you guessed. Neither can assess eye health, prove trust or tell you that touching is welcome.
