How to Speak Cat

Any of you have read this book? It's worth? I'm asking as the costumer reviews goes from "wonderful" to "worst cat book ever"

Having a foreing lenguage lover thought I could expand my skills to the non "human" lenguages wich I can practice right at home! :D

When I do,my Cat MEEEOWS,The Cats,all look,and then do,what they were doing,anyways and JJJ3,does not understand NO TREATS!
