Ferrets are prone to several health conditions that require vigilant care. Common issues include insulinoma, a type of pancreatic tumor that affects insulin production, leading to dangerously low blood sugar levels. Adrenal disease is also frequent, caused by tumors on the adrenal glands, which can lead to hormone imbalances affecting their fur and overall health. Additionally, ferrets may suffer from ear mites, heart disease like dilated cardiomyopathy, and various forms of cancer. Monitoring for symptoms such as hair loss, lethargy, and changes in appetite is crucial for early detection and management.
