How Long Do Hedgehogs Live?

Hedgehogs are beloved for their unique look, solitary habits, and quirky behaviors. As interest in owning hedgehogs as pets continues to grow, many wonder: How long do hedgehogs live? The answer depends on several factors — from their species to whether they’re in the wild or under human care. In this guide, we’ll explore hedgehog lifespans, what influences their longevity, and what you can do to help them live long and healthy lives.

Average Lifespan of Hedgehogs

Hedgehogs live considerably different lifespans depending on their environment. While wild hedgehogs face natural predators, food scarcity, and other hazards, pet hedgehogs often benefit from consistent nutrition, protection, and veterinary care.

Hedgehog Lifespan at a Glance

Hedgehog TypeAverage Lifespan (Wild)Average Lifespan (Captivity/Pet)
African Pygmy Hedgehog3–4 years8–10 years
European Hedgehog2–3 yearsUp to 10 years
General Hedgehog (All Species)2–4 years5–10 years

In short, pet hedgehogs can live up to a decade with excellent care, whereas wild hedgehogs typically live two to four years due to risks and harsh conditions.

Wild vs. Pet Hedgehog Lifespans

Let’s break down the main differences in lifespan for hedgehogs in the wild and those kept as pets:

  • Wild Hedgehogs: Face threats from predators, cars, habitat loss, disease, and food scarcity. Most live 2–4 years, with the oldest known wild hedgehogs reaching up to 16 years in exceptional cases.
  • Pet Hedgehogs (Captivity): Benefit from regular feeding, shelter, and medical attention. Average lifespans are generally 5–10 years, often cited as 8–10 for the popular African Pygmy Hedgehog.

Key Factors Influencing Hedgehog Lifespan

Several key factors determine how long hedgehogs live, both in the wild and as pets:

  • Species: Some species, like the African Pygmy, tend to live longer than others.
  • Genetics: Just like humans, a hedgehog’s genetic makeup plays a role in longevity.
  • Environment: A safe, temperature-controlled, and predator-free habitat boosts survival odds — especially for pets.
  • Diet: Nutritious food helps prevent disease and obesity, both of which shorten lifespans.
  • Veterinary Care: Prompt and regular health checks can spot problems early and extend life.
  • Stress & Handling: Low-stress, gentle handling and companionship (as appropriate for the species) contribute to long-term health.

Common Causes of Death in Hedgehogs

Understanding the risks hedgehogs face is crucial whether you want to protect wild populations or keep a healthy pet. Here are some common causes of death for hedgehogs:

  • Predation: Foxes, badgers, birds of prey, and domestic dogs/cats pose a major threat in the wild.
  • Road Traffic: Hedgehogs often fall victim to cars as they cross roads at night.
  • Pesticides & Poison: Chemicals used in gardens and agriculture can be fatal if ingested directly or via contaminated prey.
  • Parasitic Infections: Mites, fleas, ticks, and internal parasites (like lungworms) are common and can be deadly without treatment.
  • Malnutrition: A diet lacking essential nutrients, or obesity from improper feeding, can cause organ failure.
  • Cancer & Tumors: Older hedgehogs, particularly in captivity, are prone to cancer.
  • Cold Weather: Wild hedgehogs may not survive hibernation, especially juveniles with low body weight.

Stages of the Hedgehog Life Cycle

Hedgehogs go through several key phases in their lives, and their mortality risk is greatest while they’re young.

  • Birth & Early Life: Hedgehog litters average 4 to 5 young, but can be larger. About 20% of hoglets don’t survive to leave the nest. Of the remaining juveniles, 30–50% may not survive their first year.
  • Sexual Maturity: Hedgehogs reach sexual maturity around three months of age, but in the wild may not breed until their second year. Once past their first winter, survival odds improve significantly.
  • Adulthood & Old Age: Once adulthood is reached, hedgehogs can live several more years if they avoid accidents and have proper nutrition.

How to Help Pet Hedgehogs Live Longer

If you own or care for a hedgehog, there’s a lot you can do to extend their life and improve their quality of living. Here are key care tips:

  1. Provide a Spacious, Enriched Habitat: Use a secure, roomy cage with hiding places, bedding, and a running wheel for exercise.
  2. Temperature Control: Keep the enclosure between 75–85°F (24–29°C) to prevent attempts at hibernation (which domestic hedgehogs are not adapted for).
  3. Proper Diet: Feed a balanced diet of high-quality hedgehog food supplemented with insects, fruits, and occasional treats. Avoid foods high in fat, sugar, or that are toxic to hedgehogs (like dairy, chocolate, grapes, or onions).
  4. Veterinary Care: Schedule annual checkups with an exotic animal vet, and seek care promptly for signs of illness (like lethargy, loss of appetite, wheezing, or abnormal stools).
  5. Cleanliness: Keep the habitat clean to prevent infections and the spread of parasites.
  6. Gentle Handling: Regular, gentle handling helps your hedgehog stay tame and less stressed, but always respect their need for solitude and let them hide or rest as needed.

Wild Hedgehog Conservation and Survival

Wild hedgehogs face declining numbers in many regions due to habitat loss, increased use of pesticides, and road accidents. Here’s how you can help:

  • Create a Hedgehog-Friendly Garden: Leave areas of your yard wild, provide log piles, and ensure there’s access under fences for hedgehogs to roam.
  • Avoid Toxic Chemicals: Reduce or eliminate pesticide and slug pellet use to protect their natural food sources.
  • Provide Safe Shelter: Offer hedgehog houses or leave piles of leaves and brush for them to nest in.
  • Check Before Mowing or Bonfires: Always inspect long grass, compost, and piles before mowing or lighting fires to avoid harming hidden hedgehogs.
  • Drive Carefully at Night: Be vigilant when driving at night, especially in rural or suburban areas.

Frequently Asked Questions (FAQs) About Hedgehog Lifespan

How long do African Pygmy Hedgehogs live?

In captivity, African Pygmy Hedgehogs often live 8–10 years with good care. In the wild, their average lifespan drops to about 3–4 years due to natural threats.

What is the oldest recorded age for a hedgehog?

The oldest wild hedgehog documented lived up to 16 years, although this is extremely rare. Most live between 2–4 years in the wild.

What do most hedgehogs die from?

In the wild, the biggest threats are predators, road traffic, cold weather, and diseases. For pet hedgehogs, common causes of death include cancer, obesity, respiratory infections, and old age.

Can hedgehogs hibernate?

Wild hedgehogs in temperate climates hibernate through winter. Pet African Pygmy Hedgehogs are not adapted for true hibernation; cold temperatures can be fatal, so their habitats must be kept warm.

Are male or female hedgehogs longer-lived?

Current research shows no significant lifespan difference between male and female hedgehogs.

Can a better diet really help my pet hedgehog live longer?

Yes. A balanced diet rich in protein and low in fat, plus live insects and appropriate fruits/vegetables, supports longevity and overall health.

Quick Hedgehog Facts

  • Hedgehogs are nocturnal and mostly solitary animals.
  • They curl up into a ball, using their spines as a defense mechanism when threatened.
  • Wild hedgehogs eat insects, earthworms, slugs, and sometimes fruits or small vertebrates.
  • “Self-anointing” is a mysterious hedgehog behavior involving frothy saliva spread over their spines.
  • African Pygmy Hedgehogs are the most popular species kept as pets.

Conclusion

Hedgehogs, whether wild or kept as pets, are remarkable creatures with distinct lifespans shaped by their surroundings, care, and natural challenges. While wild hedgehogs often live only a few years, pet hedgehogs — especially the African Pygmy — can thrive for up to a decade with the right husbandry. By understanding the unique needs and risks hedgehogs face, we can support their health, longevity, and conservation — ensuring these spiny wonders continue to enrich our gardens and homes for years to come.
