Ferrets (Mustela furo) are wonderful pets, but like many animals, they can suffer from certain health conditions. One of the most common ailments veterinarians encounter in ferrets is adrenal gland disease. This condition occurs when a ferret’s adrenal glands overproduce sex steroids, leading to a range of symptoms that can affect the entire body.
Symptoms of Adrenal Gland Disease
The most noticeable symptom of adrenal gland disease in ferrets is abnormal hair growth or baldness, also known as alopecia. The hair loss pattern is quite distinct and can usually be recognized by veterinarians experienced in treating ferrets. While blood tests are available to confirm the diagnosis, many ferrets are diagnosed based on clinical signs and a thorough physical examination.
In addition to hair loss, overproduction of sex hormones can lead to various other symptoms. Female ferrets may develop swollen nipples and an enlarged vulva due to the excess production of sex steroids. In male ferrets, the prostate gland may enlarge, making urination difficult. Both males and females may also display heightened sexual behaviors, such as aggression or mating behaviors, despite being neutered or spayed. Interestingly, ferrets with this condition often exhibit increased itchiness, a symptom that doesn’t seem directly related to hormone levels. Although adrenal gland disease can affect ferrets of any age, it is most commonly diagnosed in ferrets older than three years.
Diagnosis and Treatment Options
Diagnosis of adrenal gland disease can be made through clinical signs and physical examination, but imaging techniques like ultrasound can sometimes help identify abnormal adrenal glands based on their size, appearance, or presence of any abnormal growths or tumors. As far as treatment for this disease is concerned, there are a few options. In the past, veterinarians performed surgical removal of the affected adrenal glands to prevent the overproduction of these hormones. Today, this invasive approach is less common, thanks to the availability of less extreme treatments.
Currently, two popular treatment methods exist for adrenal gland disease in ferrets. The first is a monthly injection that is administered into the muscle, lasting about 28 days. The second option involves an implantable injection placed under the skin, which releases medication over the course of 8 to 12 months. Both treatments help counteract the overproduction of sex hormones by slowly releasing a hormone that regulates adrenal gland function.
Adrenal gland disease is a serious condition that can significantly affect the health and well-being of ferrets. Fortunately, with advances in veterinary medicine, there are effective treatment options that can help manage symptoms and improve quality of life. If you suspect your ferret may be showing signs of adrenal gland disease, it’s important to consult with your primary veterinarian to explore diagnostic and treatment options.
