Ferrets commonly come down with sneezing and coughing due to a variety of viral diseases such as influenza (also known as "the flu"). Flu viruses can be passed from ferrets to people and people to ferrets so it is important to practice good hygiene when working around a sick ferret (or around a sick human). Although most ferret flu viruses resolve on their own, sometimes they can allow for secondary bacterial infections and even pneumonia.  If your ferret is sneezing, coughing, has a runny or congested nose, has red or swollen eyes, loses its appetite, or becomes very sleepy and quiet, veterinary care is needed. We advise that exotic pet owners pay close attention to their pets health, no matter what type of animal, and visit a veterinarian if there are any signs of illness.
