Quick update on my ever-expanding menagerie:
After initially introducing himself to the other two cats by incessant growling and hissing, Midnight has suddenly become very deferential to Monika. This happened literally overnight; evidently I missed something as I slept. Most likely Monika's patented James Coburn Zen Cool came into play.
(A clarifying note about the whole James Coburn thing: The Zen Cool specifically alludes to Coburn's deeply held personal beliefs, which he expressed in interviews, in a script he wrote with his good friend Bruce Lee, and most memorably, in a guest appearance on The Muppet Show. In Monika's case, we're referencing Coburn's role as the knife guy in The Magnificent Seven--leave him alone and you're okay, but if you push it, retribution will be swift and deserved. And this is as good a time as any to point out that even though The Magnificent Seven features Steve McQueen, James Coburn out-cools him without even trying.)
So whatever Monika did to Midnight, I'm sure it was fair--like Coburn, she'd never take it too far. And Midnight isn't off cowering in a corner, afraid to come out. He's just...respectful of his elder.
The other thing about Midnight is, he's taken to playing with some of Delmar's cat toys. Specifically these cloth, bean-baggy things, which he bats over to me, and I toss back to him, and he bats them back to me. He's not just playing, he's playing with me--clearly I've been accepted as a buddy.
This is the sort of thing the late, much-beloved Scotchie used to do, and there was a time when I would have turned into a weepy basket case, missing Scotchie and a life I used to know. Things have changed, though--now, I just play with Midnight and am happy he's here.
