I was disappointed in this book. With a title so playful as Bat's Sing, Mice Giggle, The Surprising Science of Animals' Inner Lives, I was expecting a more "heartwarming" approach to teaching the reader the science of these mysterious phenomenons. It was just too heavy handed on the science side and too dry on the emotional side for me. I enjoy science and discovering new things, but I am not a scientist, and I was expecting a more "readable" book for the average animal/nature lover.
