Sugar Glider Lifespan – How long do Sugar Gliders live?

Sugar gliders, also known as Petaurus breviceps, are small, omnivorous marsupials that are native to Australia, New Guinea, and some surrounding islands. Their average lifespan in the wild is estimated to be 5-7 years. However, in captivity, sugar gliders can live significantly longer, with average lifespans of 9-15 years.

Sugar Glider Lifespan – How long do they live?

Several key factors influence and determine the typical lifespan of pet sugar gliders:


  • As omnivores, sugar gliders need a balanced diet consisting of:
    • High-protein foods like insects, eggs, lean meats
    • Fruits and vegetables high in calcium & vitamins
    • Some sources of plant-based proteins like nuts, legumes, seeds
  • Avoid too much sugar or fat that could lead to obesity and health issues.
  • Fresh water should always be available.


  • Captive gliders should be housed in large cages or enclosures
  • Cage size recommendations:
    • Minimum 18″ x 18″ x 24″ for 1-2 gliders
    • Plus 1 cubic foot per additional glider
  • The cage should be sturdy but allow for climbing and gliding
  • Include clean bedding, nesting pouches, and toys for enrichment

Health Care

  • Annual vet exams to check for any underlying illness
  • Treatment for any parasites, infections, or injuries
  • Cleaning cages monthly to avoid buildup of waste, bacteria

How long do sugar gliders live?

With proper care, nutrition, large enclosures, veterinary oversight, and social enrichment, pet sugar gliders are capable of living up to 15 years and sometimes beyond. Their expected lifespan in captivity is significantly higher than in the wild thanks to the controlled environment.

What is the average lifespan of a sugar glider?

The average lifespan of sugar gliders can range quite a bit based on whether the animal is wild or in captivity as a pet. On average, wild sugar gliders live 5-7 years. However, pet sugar gliders typically enjoy much longer lives of 9-15 years when given proper care and diet.

Wild Sugar Gliders

Wild sugar gliders inhabiting their native habitats in the forests of Australia, New Guinea, and Indonesia live approximately 5-7 years on average.

Some key factors influencing wild sugar glider lifespan include:

  • Predators: As small prey animals, wild sugar gliders are vulnerable to predation from snakes, owls, quolls, and cats which limits lifespan.
  • Access to food: Food scarcity in the wild during certain seasons also puts survival pressure.
  • Disease/parasites: Wild populations are more prone to unchecked diseases and internal/external parasites.
  • Climate extremes: Exposure to harsh weather elements impacts life expectancy.
  • Injury risks: Hazards posed by sharp branches, thorns, falls, and accidents.

Under natural conditions with these high risks, most wild sugar gliders succumb within their first year. If they survive to adulthood, 5-7 years is typical. The maximum lifespan documented for wild sugar gliders is around 10 years.

Pet Sugar Gliders

In captivity as pets or zoo animals, sugar gliders enjoy much longer average lifespans of 9-15 years through:

  • Protection from predators, disease, and injury
  • Stable access to balanced, nutritious food year-round
  • Clean, climate-controlled cage habitat
  • Veterinary oversight and preventative healthcare
  • Opportunity to form lifelong social bonds

With diligent care by owners, removal of wild risks, and support for optimal health through diet and veterinary care, pet sugar gliders have the potential to live up to 15 years or more. The current record for the oldest captive sugar glider is an impressive 17 years.

Through responsible captive management, sugar gliders can live a decade or more beyond averages seen in the harsh wild. Their average 9-15 year lifespan as pets allows them to become cherished, long-term animal companions.

Do male or female sugar gliders live longer?

When it comes to sugar glider lifespan and longevity between the sexes, there are some small differences. On average, female sugar gliders tend to live slightly longer than males by 6-12 months in the wild and in captivity.

Here are some key factors in the lifespan differences between male and female sugar gliders:

Biological Differences

  • Reproduction: Carrying and caring for joeys may take a toll on females. But pregnancy and lactation also keep their bodies regulated.
  • Hormones: Testosterone in males leads to increased food intake but also more risks and aggressiveness.
  • Body size: Males are up to 30% larger. Larger bodies can strain the heart and organs.

Behavioral Factors

  • Territoriality: Males are more territorial and prone to fight injuries.
  • Activity: Males cover more territory and expend more energy.
  • Diet: Males eat more but are not always healthier.

Captivity Considerations

  • Breeding: In captivity, continual breeding can shorten female lifespan but increase social bonds.
  • Veterinary care: Neutering males helps curb aggression and gain weight control.
  • Diet: Equal access to a balanced diet removes gender disparities.
Sex Wild Lifespan Captive Lifespan
Female 5-8 years 10-15 years
Male 4-7 years 8-14 years

So while males may outpace females in size and strength, the female sugar glider’s reproductive adaptations, hormone balance, and generally less risky behaviors seem to promote slightly greater longevity by a matter of months in most cases. Proper care and diet can help minimize these in captivity.

What affects and shortens the lifespan of a sugar glider?

While sugar gliders may have potential lifespans of up to 15 years in captivity, there are a number of factors that can negatively impact and shorten their lifespan if not properly managed. Here are some of the key considerations:


  • Poor nutrition – Diets high in fat/sugar or lacking proper protein, vitamins, minerals, and calcium can lead to obesity, organ damage, and malnutrition which shortens lifespan.
  • Dehydration – Insufficient access to clean, fresh water contributes to kidney issues and urinary tract infections.
  • Toxicity – Exposure to anything potentially toxic such as lead, cleaning products, plants, or people’s food can poison sugar gliders.


  • Small enclosures – Cages that are too cramped lead to boredom, stress, interactivity, and trauma which reduces lifespan.
  • Unsanitary conditions – Accumulation of waste, food, and humidity facilitates bacterial/fungal growth harmful to health.
  • Improper temperature/humidity – Housing sugar gliders outside their preferred climatic range taxes their health.
  • Hazards – Sharp cage accessories and toys can injure sugar gliders and lead to serious wounds and infections.

Health Issues

  • Disease – Bacterial, viral, parasitic, and fungal diseases left untreated lead to organ damage and death.
  • Cancer – Stress and dietary/environmental risk factors can trigger mammary, liver, and other cancers.
  • Trauma – Falls, attacks, and accidents resulting in broken bones or head/spinal injury can be fatal.
  • Inbreeding – Poor genetic diversity increases the risk of birth defects and weakened immunity.
  • Neglect – Lack of basic routine care makes illness, injury, or starvation more likely.

With vigilance, proper habitat, nutrition, vet oversight, and an enriching social environment, owners can help ensure their pet sugar gliders enjoy a full lifespan free of these risk factors.
