I haven't observed that (yet?).
Maybe she likes the scent. She always licks my hands when I put on lotion. Then again I got to remember that not every kitty likes to lick hands in general. She is the first cat in my life who likes to lick hands, faces, lotion, and now acrylic paints.
It was funny how I discovered it. It was when I finished "Fairy Flowers". It was a tiny painting so it was on this tiny easel on my desk, and she sleeps on my desk (because she always needs to be where I am) and sometimes walks all over the desk for pets. She began sniffing the painting and licked away obsessively xD It was cute, but yea, probably not healthy. Since then I am super careful where I keep paint supplies, and paintings as well. Luckily, she does not like my "art table" I got last year before Inktober. She is picky about her surfaces, strange critter! ^^
