In order - Aren’t they all?, most likely, and one can only surmise. 
Seriously, if the part about the opossum is true and not hyperbole, that may be exactly what has made your cat jumpy. He smells it in the house and is absolutely certain it is going to leap out from behind the sofa and attack him at any moment. There’s a chance he may have met a few opossums in his travels and is justifiably wary of them.
The problem should abate as the smell wears off, but a really good cleaning or three might speed the recovery process.

No, it’s true. I have a possum problem. The larger adult won’t come in, the young small one will scamper right in. About a week ago, he was stuck in here for three or four days, hiding under the stove and coming out and night. Gah! I don’t even want to think about the possum poop that’s probably under the stove, but I can’t move it.
Thing is, the cat’s been acting weird for a few weeks longer than when the possum got in. Also, the cat doesn’t react to possums. At all. See, this little young possum that snuck in? Well, it sure likes cat food, and snuck back in the night before last. I guess it was Friday night. It likes to sneak in the front door, then run around the living room, hiding behind furniture I can’t move. But this time I grabbed a piece of cardboard and wedged it between the TV stand & the book case, cutting off its escape route. Grabbed it by the tail and started towards the door to throw it out.
My cat was sitting in the kitchen sitting calmly on his haunches, watching dad bull-in-a-china-closet his way around the living room after this thing. I already knew the cat doesn’t react to possums, but I was pissed off. So I dangled the possum right in front of the cat’s face and said, “see, you’re supposed to chase these things!” Nothing. The cat just sat there calmly and politely pretending to not notice the plump, juicy squirming little possum I was holding three inches in front of his face. He kept looking around at the walls, ceiling. “La, la, la. Dum-duh-dee-dum-dum. Don’t see anything!”
It’s like there’s some ancient, sacred ancestral pact between cats & possums. Cats are somehow forbidden to react to or interfere with them. Grr.
I mean, if it were a mouse, well boy howdy. He’d be all over that. He’d torture it for hours.
