How Long Do Hedgehogs Live? Lifespan & Health Guide [2026]

How Long Do Hedgehogs Live?

The African Pygmy Hedgehog (Atelerix albiventris), the species most commonly kept as a pet, has an average lifespan of 3-5 years in captivity. With excellent care and favorable genetics, some hedgehogs live up to 7-8 years, though this is the exception rather than the rule.

Compared to other small exotic pets:

Factors That Affect Lifespan

Genetics

Genetics is the single biggest factor in hedgehog longevity. Inherited conditions like Wobbly Hedgehog Syndrome and cancer predisposition can significantly shorten lifespan. This is why purchasing from a reputable breeder who tracks health lineage across generations is so important.

Diet

A proper diet directly impacts lifespan. Key dietary factors include:

• Low-fat food (under 15% fat) prevents obesity and fatty liver disease
• High-quality protein supports immune function and muscle maintenance
• Controlled treat intake — overfeeding insects causes obesity
• Fresh water daily — dehydration stresses the kidneys

See our hedgehog diet guide for detailed feeding recommendations.

Exercise

Hedgehogs are naturally active and need a proper running wheel (12" solid surface) for nightly exercise. Sedentary hedgehogs are far more prone to obesity, heart disease, and depression. Most healthy hedgehogs run 3-8 miles per night on their wheel.

Environment

• Temperature: Maintaining 72-80°F prevents dangerous hibernation attempts and chronic stress
• Cleanliness: A dirty cage leads to respiratory infections, skin problems, and mite infestations
• Stress: Loud environments, frequent cage changes, and rough handling increase stress hormones
• Light cycle: Consistent 12-14 hours of light prevents hormonal imbalances

Veterinary Care

Access to an exotic animal veterinarian experienced with hedgehogs is essential. Many common hedgehog health issues are treatable when caught early but become fatal when ignored.

Common Health Issues

Wobbly Hedgehog Syndrome (WHS)

WHS is a progressive, degenerative neurological disease that is one of the most serious conditions affecting pet hedgehogs.

• Cause: Genetic — inherited demyelinating condition
• Onset: Usually between 2-3 years of age, but can appear as early as under 1 year
• Symptoms: Wobbling hind legs, falling over, progressive paralysis, muscle wasting, weight loss
• Progression: Gradual paralysis spreading from hind legs to the entire body over 12-18 months
• Treatment: No cure exists; management focuses on quality of life
• Prevention: Buy from breeders who track WHS in their lines for multiple generations

Obesity

Obesity is the most preventable health issue in pet hedgehogs.

• Causes: Overfeeding high-fat treats, lack of wheel exercise, high-fat kibble
• Complications: Fatty liver disease (hepatic lipidosis), heart disease, diabetes, reduced mobility
• Prevention: Measured portions, low-fat food, daily wheel access, weekly weigh-ins

Cancer and Tumors

Cancer is unfortunately common in hedgehogs, especially those over 3 years of age.

• Most common types: Oral squamous cell carcinoma, mammary tumors, lymphoma
• Signs: Lumps or bumps anywhere on the body, weight loss, difficulty eating, lethargy
• Treatment: Surgical removal when caught early; prognosis varies by type and location
• Monitoring: Check your hedgehog's body during handling for any new lumps

Dental Disease

Hedgehogs are prone to dental problems, including tartar buildup, gum disease, and tooth loss.

• Signs: Difficulty eating, drooling, pawing at the mouth, bad breath, weight loss
• Prevention: Dry kibble helps scrub teeth; annual dental checks by your vet
• Treatment: Professional dental cleaning under anesthesia, tooth extraction if necessary

Mites and Skin Infections

External parasites and skin infections are common and highly treatable.

• Mites: Cause flaky skin, excessive scratching, quill loss; treated with Revolution (selamectin)
• Fungal infections (ringworm): Cause crusty skin, hair loss around face; treated with antifungal medication
• Bacterial skin infections: Often secondary to mite damage; treated with antibiotics

See our hedgehog quilling guide for how to distinguish normal quilling from mite infestations.

Respiratory Infections

• Causes: Cold temperatures, dusty bedding, drafty environments
• Signs: Sneezing, nasal discharge, labored breathing, wheezing, lethargy
• Treatment: Antibiotics prescribed by an exotic vet
• Prevention: Maintain proper temperature, use low-dust bedding, avoid drafts

Signs of Illness

Hedgehogs instinctively hide illness, so subtle changes often indicate a problem. Watch for:

• Weight loss or sudden weight gain — weigh weekly to catch trends
• Reduced activity — less wheel running, more sleeping
• Appetite changes — eating less, refusing favorite treats
• Changes in droppings — green, tarry, bloody, or very loose stool
• Labored breathing — open-mouth breathing, wheezing, clicking sounds
• Discharge from eyes, nose, or ears
• Wobbling or loss of balance — may indicate WHS
• Lumps or bumps — check during handling
• Excessive scratching — may indicate mites or fungal infection
• Reluctance to uncurl — may indicate pain

Any of these symptoms warrants a vet visit. Do not wait and see — hedgehog health can deteriorate rapidly.

Veterinary Care Schedule

Finding an Exotic Vet

Not all veterinarians are experienced with hedgehogs. To find a qualified exotic vet:

• Search the Association of Exotic Mammal Veterinarians (AEMV) directory
• Ask hedgehog breeders and local hedgehog communities for recommendations
• Call ahead and confirm the vet has specific experience with hedgehog care
• Establish a relationship before an emergency arises

Quality of Life Considerations

As hedgehogs age, especially past 3-4 years, quality of life monitoring becomes important. Consider these factors:

• Is the hedgehog still eating and drinking normally?
• Is the hedgehog still using the wheel and exploring?
• Is the hedgehog in visible pain or discomfort?
• Can the hedgehog perform normal behaviors (walking, curling, anointing)?

Work with your veterinarian to make compassionate decisions about end-of-life care. Hedgehogs with terminal diagnoses (advanced WHS, inoperable cancer) may benefit from palliative care focused on comfort.
