This book tells you why cats knead, why cats hiss and so much more. A great book for if you want to know why your cat does what it does. It has beautiful illustrations and is written very well. There are 40 fascinating facts about cats and their behaviors. Karen Anderson and Wendy Christensen are both devoted cat lovers. Karen Anderson also wrote Cats Have No Masters... Just Friends and The Cat-Sitter's Handbook: A personalized Guide for Your Pet's Caregiver. I would totally recommend this book!
