Ferrets can catch colds and the flu just as we do. They will also display the same symptoms that we do: runny or stuffy nose, watery eyes, sneezing, coughing, and loss of appetite. One particular problem is the human viral influenza type A. If anyone in your household is experiencing symptoms of a cold or flu, you should not let your ferrets come in contact with them. Ferrets can easily catch your cold or flu and your sick ferret can then re-transmit the disease back to you.
Usually, there is no need for medication; just make sure your ferret drinks plenty of water and is placed away from drafts. However, if the symptoms become chronic and/or persist for more than three days, you will need to take your pet to the vet. One word of caution, never give aspirin to a ferret.
