Marshall has been raising ferrets since 1939. The company founder, Gilman Marshall, began raising ferrets as a hobby for hunting, and also sold them as pets. It was later realized that ferrets also proved to be a valuable model in the development of canine distemper vaccines. Since then, the domestic ferret has become recognized as a valuable model for several areas of biomedical research including: neuroscience, myocardial infarction, cystic fibrosis, to evaluate emesis response, and most notably, influenza vaccine development.
