Trouble has settled in well. He still wants to spend a lot of time outside, but he comes when I call so I can get him inside when I need to. He wakes me up every morning meowing to go outside! Th other cats don't mind him much any more. Madness still growls when he come very close to her, but as long as he doesn't try to basically sit on top of her, she is OK with him. Bubbles actually plays with him!
Mrs. B doesn't mind Trouble at all. She pretty much just ignores him, which is also what she does with Bubbles and Madness. Mrs. B is continuing to improve, so I'm hoping she is over the worst. She is not totally back to normal, but she is MUCH better than last week.
