In feline signaling, a hard stare carries pressure while a slow narrowing and half-closed eyes convey relaxation and non-threat, popularly called the cat kiss.
Behavioral observations link slow blinking to positive emotional states, and cats tend to approach more after humans slow-blink at them, a widely accepted interaction pattern.
To respond, hold a soft gaze, close your eyes slowly for a second or two, reopen, and repeat without leaning in or reaching out to break the cat's rhythm.
One distinction matters: pain also makes cats squint, so squinting with flattened ears and a tense body should be checked as a health signal, not read as affection.
