Abstract
This case study tells the story of “Norrie,” a green iguana who is adopted as a companion animal and becomes sick. Norrie is brought to a veterinarian and is diagnosed with a metabolic bone disease caused by a nutritional deficiency of calcium. The story introduces students to the field of animal nutrition as they examine the components of Norrie’s diet and consider nutrition-associated diseases. They also learn about the elements of a feeding trial and are asked to design their own through a series of guided questions. A concluding exercise provides students an opportunity to apply their newly acquired knowledge to other nutrition-related diseases observed in exotic pets by reading and synthesizing primary literature. The scientific content of this case is ideally suited for use during the macromolecules unit of a college-level biology course or during the nutrition unit of an animal science course. The case also provides a platform for thoughtful discussion of issues surrounding the ethics of owning, selling, and treatment of exotic pets.
