For this Photo Hunt I am recommending a very informative book titled: Is Your Cat Crazy? Solutions from the Casebook of a Cat Therapist by John C. Wright and Judi Wright Lashnits.
I borrowed this book from my local library and I found it very interesting and informative. It's written by a cat behaviorist and was filled with problems and solutions that were quite logical and for the most part easy to implement. I learned a lot from this book, and I certainly recommend it!
