Ferret distemper is a highly contagious viral disease that primarily affects ferrets. It is caused by the canine distemper virus, which can also infect other animals like dogs and raccoons. Symptoms include fever, nasal discharge, coughing, and gastrointestinal issues. The disease can progress rapidly and is often fatal if not treated promptly. Vaccination is the best way to prevent ferret distemper. Ferrets should receive their first vaccine at around 8 to 12 weeks of age, followed by booster shots. Early detection and supportive care can improve the chances of recovery, but prevention through vaccination is crucial for keeping ferrets safe.
