Dr. Barbara Natterson-Horowitz, a cardiologist at the UCLA Medical Center, coined the term "zoobiquity" to describe the idea of looking to animals and the doctors who care for them to better understand human health. Veterinary medicine had not been on her radar at all until about 10 years ago. That's when she was asked to join the medical advisory board for the Los Angeles Zoo and she began hearing about "congestive heart failure in a gorilla or leukemia in a rhinoceros or breast cancer in a tiger or a lion."
