The cat on the outside I call "Norman". I don't know who Norman belongs to, but I gave him shelter in my carport during a brutal cold spell in January, and he was joined by his girlfriend (and I think also his sister). As you probably know, I took Grace in when I realized she was pregnant, and we now have five week old kittens, one of whom is the spitting image of Norman!
Norman and Grace seem to have a genuine fondness for each other that goes beyond lust, and this was not a staged reunion. The kitten was not at all afraid, and actually went up and touched the screen with her paw.
I call it, "Mommy, who's that man?"
I hope this works.
