Common health issues, care information, and frequently asked questions
What is Adrenal Disease?
Adrenal disease is one of the most common health issues in ferrets. It occurs when the adrenal glands produce excess hormones. Symptoms include hair loss (usually starting at the tail), enlarged vulva in females, difficulty urinating in males, and increased aggression.
Treatment options include surgery to remove the affected gland or Deslorelin (Suprelorin) implants, which suppress hormone production. Early detection and treatment lead to the best outcomes.
What about Broken / Worn Teeth?
Ferrets are prone to dental issues, particularly broken or worn canine teeth. This can happen from chewing on cage bars, hard toys, or simply from age. Broken teeth can become infected and painful.
Regular dental checks are important. If a tooth is broken below the gum line or shows signs of infection, extraction may be necessary. Switching to softer foods and removing hard chew items can help prevent further damage.
What is a GI Blockage?
Gastrointestinal blockages are a life-threatening emergency in ferrets. Ferrets are curious and love to chew on rubber, foam, and other soft materials that can become lodged in their intestines.
Signs include: loss of appetite, lethargy, pawing at the mouth, thin/string-like stool or no stool, and vomiting. If you suspect a blockage, seek emergency veterinary care immediately — this is a surgical emergency.
Prevention: Ferret-proof your home thoroughly. Remove all rubber, foam, sponges, and small objects from their play areas.
What is Lymphoma?
Lymphoma is the most common cancer in ferrets. It affects the lymphatic system and can present in several forms. Symptoms vary but may include enlarged lymph nodes, weight loss, lethargy, difficulty breathing, and chronic diarrhea.
Treatment may include chemotherapy, prednisone, or supportive care depending on the type and stage. Some ferrets respond well to treatment and can enjoy good quality of life for months or even years.
What is Cardiomyopathy?
Cardiomyopathy is a heart condition where the heart muscle becomes enlarged and weakened. It’s relatively common in older ferrets. Symptoms include lethargy, coughing, difficulty breathing, fluid retention, and hind-leg weakness.
While there is no cure, medications can manage symptoms and improve quality of life. Regular vet checks help with early detection.
What is Insulinoma?
Insulinoma is a tumour of the pancreas that causes overproduction of insulin, leading to dangerously low blood sugar. It’s extremely common in ferrets over 3 years old.
Symptoms: glazed eyes, drooling, pawing at the mouth, hind-leg weakness, lethargy, seizures, and collapse.
Emergency tip: If your ferret is having a low blood sugar episode, rub a small amount of honey or corn syrup on their gums and contact your vet immediately. Do NOT force liquids into their mouth.
Management includes frequent small meals, prednisolone, and in some cases surgery.
What is Supportive Care / Palliative Care?
As ferrets age or face chronic illness, supportive (palliative) care focuses on maintaining comfort and quality of life rather than curing the disease.
This may include: pain management, assist-feeding (duck soup, syringe feeding), fluid therapy, warmth and comfort (heated beds), and reduced stress environments.
Our foster families are experienced in providing supportive care, and we work closely with our veterinarians to ensure every ferret is comfortable and loved.
What is ECE (Epizootic Catarrhal Enteritis)?
ECE, commonly known as “green slime disease,” is a highly contagious viral infection that affects the intestinal lining. It causes bright green, slimy diarrhea, loss of appetite, lethargy, and dehydration.
It’s most dangerous in older ferrets and those with other health conditions. Treatment includes supportive care, fluids, bland diet, and monitoring. Most ferrets recover but may have lingering digestive issues.
New ferrets should be quarantined for at least 2 weeks before introducing them to existing ferrets to prevent ECE transmission.
Are Ferrets Wild Animals?
No! Domestic ferrets (Mustela putorius furo) are fully domesticated animals that have been kept as pets for over 2,000 years. They are not wild animals and cannot survive on their own in the wild.
They are related to weasels, mink, and otters, but domestic ferrets are as far removed from their wild cousins as dogs are from wolves. They depend entirely on humans for food, shelter, and care.
Never release a domestic ferret into the wild. If you can no longer care for your ferret, please contact us — we will help.
