>Is a slow blink from a cat a term of endearment or is she tired?
love. Since a fixed stare can be a sign of challenge (depending on posture
and *** expression) I wonder if a slow blink "says", "I am
deliberately not challenging you, see, here's a blink." A human handshake
has a similar origin; showing that the right hand held no weapon.
When my cat is lazy and happy, she looks directly at me and blinks slowly.
When she is really sleepy, she looks into space, blinks, and yawns hugely.
The key is whether there is eye contact.
I'd welcome any corrections.
