It's very possible that Boo will be more accepting of the situation now. She may understand what's going on better after Nancy opened the line of communication.

My cat Shai was a terror from the time I got her. When Nancy read her, she told me that Shai was angry at me for thinking she was afraid of me or anything! Shai and I ended up with a better understanding of each other. Now Shai is less angry and more accepting of all the other cats and even sits on my lap sometimes. It was an amazing transformation.

I saw the difference in attitude almost immediately. And it keeps getting better all the time.

Some of Boo's anger may also be fear that she will be moved around again. If she knows that isn't going to happen, maybe she will be less angry.
