Query: Every cat owner (or everyone owned by a cat) should have this book!

The "HOW-TO BOOK FOR MULTIPLE CAT OWNERS!" This book has lots of valuable information for the multiple cat owner! I've had cats for 35 years and I wish I knew the helpful hints included in this book years ago. It is heartbreaking to hear of people who have to give up their newly adopted felines because they can't get along with the established household cats. This book will help prevent these types of problems. I have two eight-year-old cats and four two-year-old cats. This book is very helpful even now but I wish I had it when I adopted my four "newbies." It helps you understand how a cat thinks and why they react like they do in different situations. I haven't tried the feliway plug-in yet but I intend to. SUPER GREAT BOOK!
