I'm not an expert on this but isn't this why they mede "cat girls" who are "really 800 year old nature goddesses"?
1. Not a human (cat ears)
2. 800 years old (according to plot)

I just remember reading an article somewhere about this "loophole" in anime. Also I like cat (or any pointy) ears on an (adult) girl.
NOTHING ELSE, just ears.
