If you want a book that investigates the biological behavior of feral and tame domesticated cats I recommend this book. There are a lot cat books out there on the market, I have read nearly all of them (99% of them are repetitive drivel). There rest are mnostly diluted dumbed down versions of this one. Previous reviewers obviously did not actually read or understand this book or how research and it's processes work.
This book was written by people that have actually done research in the field of animal behavior (recent), and on domestic cats (e.g. Dennis Turner did behavioural research on domestic cats). In order to understand and effectively help a cat you actually need to understand it's feral and tame counterparts. Current behavioural research on felines is limited, and in the early to mid part of the last century there was a lot of valuable research was done. Research on the domestic is currently not seen as alluring, but I have a certain feeling that that will change in the next couple of years, as research currently being conducted comes to light and will change certain people perceptions of their feline companions and why they do what they do. I am actually an animal behavioural ecologist/cognitive therapist, specializing in wild and domestic felids. This book helped me get up to speed when I was starting my MSc and PhD research a few years back. Granted it was not written with Fluffy and Trixie exclusively in mind--it is looking at the domesticated cat (feral and otherwise). It is slightly basic for those doing more advanced research on domestic felines--post graduate level--and I personally take exception to the research methods (outside this publication) of one particular contributor to this work (Bradshaw=sloppy), but it's a good starter book for anyone that wants to understand domesticated felines and why they do what they do.
This is actually one the books that I recommend to interested clients that want to understand cats as a species followed by Bonnie Beaver's feline behavior book for veterinarians.
