I approached this book thinking it would be a great way for me to connect my love of (and respect for) animals to my own search for self-insight. I came out with that, but also learned a lot more! Each description of an animal comes with that creature's "message" and "warning" which is actually a psychological aspect of yourself,and it really helped me to consider how, for example, the life and behavior of a mouse relates to my life and choices I am making.
Although this is listed as a reference book, I recommend reading the whole book as a self-help guide. It really helped me open my mind to how much we humans can learn from the rest of the animal kingdom!
