The name “ferret” comes from the Latin furo, meaning thief—a well-earned name, as they are experts at squeezing into tight spaces, finding small misplaced objects around the house, and hiding them in their secret stashes—under the sofa or even inside the oven drawer! Knowing this, it’s easy to understand how they can sometimes get themselves into trouble. To prevent mishaps, it’s best to provide a large, secure cage and supervise their time outside the enclosure. After plenty of playtime, ferrets enjoy returning to the comfort of their cage to nap between activity periods—they are champion sleepers! As adorable as they may look curled up in their hammock, it’s important to resist the urge to wake them for our own entertainment. Sleep is precious.

Ferrets are known for their distinct musky odor. This scent comes from sebaceous glands (which produce sebum) distributed throughout their skin. The odor is reduced in spayed or neutered animals, but no procedure can eliminate it entirely. Because ferrets are mustelids (like skunks), they also have anal sacs that can release unpleasant secretions. However, the vast majority of ferrets sold in North America have these glands removed at a young age during their spay or neuter surgery. Rest assured—you won’t be “sprayed”!

Like cats, ferrets are strict carnivores. They require a diet high in protein (30–35%) and fat (15–20%), but low in carbohydrates and fiber. Commercial ferret diets formulated specifically for adult and growing ferrets are recommended to support optimal health. An inappropriate diet can lead to serious health issues, including urinary problems.

Ferret stools may appear softer than those of cats and dogs, and this can be normal. However, they should always be well formed. If your companion develops diarrhea, greenish stools, or mucus in the stool, they should be evaluated by a veterinarian.

Like cats, ferrets ingest hair while grooming. In some cases, a laxative paste may be recommended to help prevent hairball formation in the digestive tract.

Yes. Ferrets should be vaccinated against distemper and rabies. Ferrets are highly susceptible to canine distemper virus, which also affects dogs. Infection is often fatal, so prevention is essential. Like dogs and cats, ferrets can also contract rabies. An annual veterinary exam is recommended to monitor your companion’s health and keep vaccinations up to date.

Compared to dogs and cats, ferrets have a relatively short lifespan—typically 8 to 10 years. By 5 to 6 years of age, a ferret is considered geriatric and at higher risk of developing age-related diseases. Several types of cancer are documented in ferrets, and they can be difficult to detect at home. Regular veterinary checkups are important for early identification of health concerns.

As ferrets age, they commonly develop adrenal gland disease (the adrenal glands are located above the kidneys), resulting in overproduction of sex hormones. Signs may include hair loss, itching, vulvar swelling, and behavioral changes. This condition is typically managed with monthly injections or the placement of an implant and can yield good results. While it is not curable, treatment can provide a good quality of life for many months or even years. Surgical removal of the affected adrenal gland is also an option, though it can be delicate—particularly if the right gland is involved, as it lies close to the vena cava, a major abdominal blood vessel.

Male ferrets with adrenal disease may have difficulty urinating due to prostate enlargement. Difficulty urinating is a medical emergency and requires immediate veterinary attention.

Nausea in ferrets often presents as yawning, excessive salivation, and pawing at the mouth. If you observe these signs, contact your veterinary hospital promptly.

Any small change in your ferret’s habits should be taken seriously. For example, a normally playful ferret who becomes lethargic and sleeps more than usual may be affected by an insulinoma (a tumor that produces insulin). This condition lowers blood sugar levels, leading to decreased energy.

Curious and energetic, most ferrets enjoy exploring new environments. However, their movements must be closely supervised. Ferrets can be trained to wear a harness for short walks. Because they are sensitive to heat, always provide water and avoid outings in hot weather.

Please note that ferrets with outdoor access are at greater risk of parasite infections, such as fleas or even heartworm. Although heartworm is less common and typically occurs in small numbers, it can still cause serious health problems. Preventive care is the best approach—discuss parasite prevention options with your veterinarian.

Ferrets can share certain human illnesses, which is one reason they are used in research. They are susceptible to several strains of human viruses, including influenza (the flu) and SARS-CoV-2 (the virus responsible for COVID-19). Close contact with your ferret should be avoided if you have respiratory symptoms, just as you would with another person.
