Grandin bases the discussions in this book on the idea that we can improve animals' lives by paying attention to the "blue ribbon" emotions. She believes that instead of trying to correct or control an animal's behavior, we should understand the emotions behind the behavior, ameliorate situations that increase unhelpful emotions and promote stimulation of good emotions.

In particular, Grandin talks about Seeking, Fear and Frustration, with Frustration being a mild form of Rage. Throughout the book, Grandin suggests ways to pique the Seeking emotion to counteract Fear and Frustration in various animals.

Some chapters will be more interesting to some people than others. She begins with dogs and cats and then moves into livestock (horses, cows, chickens, pigs) and lastly into zoo and wild animals. However, there is some cross-over in the stories as she compares and contrasts behaviors. While most of the livestock discussions are on large-scale farms or ranches, some of the concepts could help small or hobby farmers to understand their animals more.

Also interesting is the discussion of how people act around and react to animals.
