The list author says: "Doing the volunteer work that I do with cats (tracking their behavior, answering customer questions, and just keeping them entertained) I'm pretty determined to find the best most definitive books on cat behavior and, to a lesser extent, medical care. This list contains my findings so far. I attempt to list books from novice to advanced."
"BASIC. If I could only own one book on cat behavior, this would be it. Pam Johnson-Bennett is perhaps the top author on owner-oriented books on the subject. If you're going to buy a book on the subject, buy this first. I wish my local shelters would recommend this or sell it at a discount to first time cat adopters."
"BASIC to INTERMEDIATE. Everyone who owns a cat and isn't a small animal veterinarian should really own this book. For free you can download and keep most of the important stuff in the first chapter on emergency care just by downloading the free kindle sample."
"ADVANCED. When you're interested in getting beyond the basic and "self help" (or perhaps "owner help") type books on feline behavior, and you want to get into more academic technical detail, this book is excellent. Bonnie V. G. Beaver is probably the foremost technical/veterinary author on the subject of feline behavior."
"ADVANCED. This is a rather technical reference book that is not entirely devoted to cats, but many of the entries in the book pertain to cats. My guess is that most laypeople will get all of the technical knowledge they want from the Feline Behavior book by the same author."
