Dr. McConnell is one of my favorite behaviorists, all of her books are terrific. I've also had the pleasure of going to one of her seminars - definitely a must if you have the opportunity. She also has a radio show every Saturday on NPR called "Calling All Pets" where she answers behavior questions from people who call in. If you don't get NPR in your area, you can listen to the shows online here - http://www.wpr.org/pets/
