There are much better books on this topic. "Animal Speak" for example. This book seems like it was a commissioned knock off in order for some publisher to get on the animal totem bandwagon.
The information in it is superficial and not based in much. The authors interject their politics, opinions, and psychic predictions into the material which was not what I was expecting.
This book would have to be an introduction or entry-level book.

This is the best book because I am in it. It was written by my two aunts Trish and Millie. They love animals and know a lot about us and all we represent. Trish calls me Oh Jackson and Millie calls me the General because I like to sit on the steps by the window and guard the house. I am always on alert in case the badman returns. But I am slowly making friends with some nice men. This book will make you really appreciate all of us. There's lots more to animals than they taught you in grade school.
