A revelatory depiction of what animals can teach us about the human body and mind, exploring how animal and human commonality can be used to diagnose, treat, and heal patients of all species.

"Full of fascinating stories.” —Atul Gawande, M.D.

Do animals overeat? Get breast cancer? Have fainting spells? Inspired by an eye-opening consultation at the Los Angeles Zoo, which revealed that a monkey experienced the same symptoms of heart failure as human patients, cardiologist Barbara Natterson-Horowitz embarked upon a project that would reshape how she practiced medicine.

Beginning with the above questions, she began informally researching every affliction that she encountered in humans to learn whether it happened with animals, too. And usually, it did: dinosaurs suffered from brain cancer, koalas can catch chlamydia, reindeer seek narcotic escape in hallucinogenic mushrooms, stallions self-mutilate, and gorillas experience clinical depression.

Natterson-Horowitz and science writer Kathryn Bowers have dubbed this pan-species approach to medicine zoobiquity.
