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.
One signal, more than one function
International Cat Care explicitly notes that slow blinking is not necessarily an invitation to touch or stroke a cat. It can be friendly, and it can also occur when a cat feels vulnerable. Treating every blink as consent loses that distinction.

Approaching is not a blanket yes
The research measured approach behavior after an invitation. It did not test a universal rule about petting. A cat coming closer does not authorize restraint, picking up or an extended interaction. Keep the research result at the scale it actually measured.

Contact has its own pauses
International Cat Care's greeting guide describes letting cats initiate and allowing pauses rather than continuing indefinitely. Read that guide for the full context. The central point here is that a blink does not replace attention to what the cat chooses next.

Make withdrawal easy
Avoid cornering or leaning over the cat. Leave room for an interaction to end without following or trying again. Respecting that ending does not depend on first deciding whether the blink meant comfort, friendliness or something else.
