What the picture shows

A small grey-and-white cat sits upright with a droopy, half-closed-eyed expression and one paw slightly raised, in a soft low-contrast photo. Chatters likely use it as a lazy, half-hearted wave or greeting, or to convey being tired and unimpressed.

No measured meaning yet. Used 10 times in 6 channels this month; one is written once chat gives enough evidence.
