Maintaining good ferret health involves regular veterinary check-ups, a balanced diet, and proper hygiene. Ferrets are prone to certain health issues, such as insulinoma, a type of cancer affecting insulin production, and adrenal disease, which can lead to hormonal imbalances. Vaccinations and parasite control are also essential for preventing diseases. A healthy ferret should have a shiny coat, clear eyes, and an active demeanor. Owners should monitor their pets for signs of illness, such as lethargy, loss of appetite, or unusual behavior. Providing a safe environment and mental stimulation can further enhance a ferret's well-being.
