Jack and Diana Fallenstein began raising ferrets in the fall of 1985 in rural northern Pennsylvania. What began as a very small family owned ferret operation, providing animals for the pet and later biomedical industry, has become one of the largest ferret breeding operations in the world. Not only do we support biomedical research in the United States, but also provide healthy specific pathogen free ferrets to international users as well.

For decades, we have been the only breeder of influenza-free ferrets in the United States providing high quality, healthy animals for the continued research and development of preventatives and therapies against the Influenza virus. As a family operated business, the quality, health, and well-being of the ferrets we raise are our number one priority.

With over 30 years of experience breeding ferrets, we understand the importance in maintaining regulatory compliance in order to provide the best research model possible. With this in mind, we have acquired a new facility that allows us to comply with current facility recommendations as well as the ability to continue to advance with the changing biosecurity needs in order to maintain influenza free ferrets. We strive to progress with the biomedical industry adapting to new regulatory requirements and suggestions as necessary.

We invite our current customers as well as potential new customers to tour our facility to appreciation the dedication applied to raising the healthiest and hardiest ferrets available to the biomedical research industry.
