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 group finding is not an individual promise
The experiments compared behavior across cats and conditions. They do not guarantee that a particular cat will respond at a particular moment. No reply is not a scientifically established rejection signal or a score for the relationship.

Do not manufacture the missing answer
Calling repeatedly, moving closer or holding a cat for eye contact changes the interaction. It also removes the choice that cat-friendly greetings are meant to preserve. You can stop without resolving what the non-response meant.

Keep unknowns as unknowns
A useful note might say: I blinked, the cat remained on the chair, and I did not notice a response. It need not add bored, angry, trusting or unloving. Describing the limits of an observation is more honest than filling them with a story.

Separate concern from curiosity
This page cannot decide whether a new change has a medical cause. If you are concerned about health or behavior, ask your veterinary team rather than using a blinking exercise as a test. A worksheet is not a route for urgent help.
