One pet that’s gaining popularity throughout the world is the ferret. This friendly mammal needs certain special care regarding their health. So in the following article, we’re going to tell you about the most common ferret diseases so you can treat them in time.

What are the most common ferret diseases?

Although these animals were domesticated thousands of years ago to hunt rabbits, ferrets only recently became pets. In fact, some eccentric celebrities chose these mammals as pets as if they were dogs. Ferrets are usually around 20 inches long, and weigh less than 5 pounds.

However, one reason this species has become popular is how peaceful they are when they sleep. They sleep 18 hours a day. Ferrets are also very sociable creatures. They love to play. As a result, these animals have become popular pets in recent years.

Some common ferret diseases can be fatal.

In turn, this has led to veterinarians becoming better prepared regarding their health and care. So let’s take a look at the most common ferret diseases:

1. Internal parasites

The most frequent parasites in ferrets are giardia and coccidia. These cause vomiting, diarrhea, and loss of appetite. Treatment includes antiparasitic drugs that are usually for treating cats. However, your vet will prescribe a lower dosage. You should always consult the vet about the appropriate amount.

2. Hyperestrogenism

This is a disease that appears in young females up to two years old. It’s characterized by excessive production of estrogen, caused by continuous heat. This can cause aggravated anemia if not treated early.

3. Ear scabies

This is a disease the affects mammals’ ears, and ferrets are no exception. It’s produced by a particular species of mite. When pets suffer from ear scabies, their wax production and itchiness of their ears increase.

One of the common ferret diseases is ear scabies.

You can tell if your ferret has ear scabies if the animal moves their head side to side, scratches itself with its front legs, or rubs itself against objects. Your vet will probably prescribe an antiparasitic for cats. However, it’s very important to tackle this disease quickly to avoid ruptured eardrums or severe ear infections.

4. Distemper

Another of the most common ferret diseases is distemper. This is also a common disease with cats and dogs. Animals usually contract this disease from other pets. Unfortunately, distemper can be fatal.

However, you can prevent this disease with a vaccine that a vet will give your ferret at eight weeks of age. Then, they will give your pet a booster dose every year.

5. Ferret diseases: Sarcoptic mange

Sarcoptes scabiei mites cause this skin disease. You can easily recognize the symptoms of mange. The symptoms are abundant itching, scabs, and loss of fur.

6. Rabies

This is one of the most dangerous ferret diseases. It’s also dangerous because it can be spread to other pets in the house, as well as family members.

As a result, the best way to avoid this disease is through vaccination. A vet should be given another dose annually.

Other ferret diseases

Vets can treat most common ferret diseases with antibiotics, antiparasitics, or vaccines. However, there are other diseases that occasionally affect ferrets:

1. Lymphoma

Ferrets, like other animals, can suffer from cancer in general. They can also suffer from cancer that affects the immune system. Lymphoma generally appears before the ferret is two years old. Treatment includes chemotherapy.

2. Insulinoma

This is a tumor in the pancreas. An increase in the production of the hormone insulin causes this type of tumor. However, it’s important that you take your ferret to the vet for proper testing to determine if they have this disease. Then, a vet can help you determine the best treatments available.

3. Ferret Diseases: Adrenal disease

This disease can appear in sterilized ferrets. In males, it causes complications when urinating. In females, there’s inflammation of the vulva. Excess production in the adrenal glands can unbalance the ferret’s metabolism and cause other diseases.
