Sugar Glider

Coat and looks how to spot one

Thick, soft fur; furred gliding membrane between front and back legs; long bushy tail

A palm-sized marsupial about as big as a large hamster, with a body of roughly 13-21 cm and a tail that is about as long again. The fur is dense and velvety, classically blue-grey on top with a creamy throat, chest and belly. A dark stripe runs from the nose along the middle of the back, and darker bands frame each eye and reach toward the ears. Big, widely set eyes give it good night vision. A thin, furred skin membrane stretches from the outer finger of each front foot to the first toe of each back foot, so when it spreads its limbs it becomes a small living glider. Each hind foot has a clawless grasping toe that works like a thumb, and two partly joined toes that it uses as a grooming comb. Females carry their young in a belly pouch.2165

Personality what they are like

Sugar gliders are energetic, curious night owls that spend the day curled up asleep in a nest and wake up full of bounce after dark. They are very group-minded animals that groom each other and share scent to mark who belongs. Many pet gliders become tame enough to climb onto their keepers' hands, though they need time, patience and daily contact to build that trust. They can be vocal, using barks, hisses and other calls to talk to each other.261

Daily activity how busy a day looks

High, and mostly at night. Gliders need tall space to climb, leap and explore, with plenty of branches, horizontal shelves, ladders, swings and ropes. A solid-surface exercise wheel with no open rungs is recommended. Daily supervised time outside the cage in a safe, glider-proofed room adds exercise and variety, but they must be watched the whole time.896

Grooming and care the hands-on bits

Gliders keep their own coats tidy and groom one another, so they need little brushing. Day-to-day care is mostly about feeding in the evening, keeping fresh water available, and cleaning the cage, nest pouch and bedding regularly. Good bedding choices are shredded paper, paper towels, recycled paper or aspen shavings; skip pine and other softwood shavings and loose cotton fluff. Any branches collected from outside should be from safe trees such as apple or untreated citrus and baked at 200-250 F for at least 30 minutes before use.82

Home where they are happiest

Height matters more than floor space. Merck suggests at least about 90 x 60 x 90 cm (36 x 24 x 36 in) with bar gaps of no more than 1.25 cm (0.5 in); MedVet advises even narrower bars, and Purdue gives a smaller minimum of 20 x 20 x 30 in. Powder-coated wire is a common choice; avoid galvanised wire. Hang a wooden nest box or fleece pouch high up for daytime sleep, and furnish the cage with branches and shelves. Sources differ on temperature: Merck puts the comfort zone at about 27-31 C (80-88 F) within a wider tolerated range of 60-90 F, while Purdue suggests 65-75 F. Keep the cage out of draughts and direct sun.5896

Food basics what goes in the bowl

Omnivore. In the wild they eat insects in the warmer months and switch to tree gums, sap, nectar, manna and honeydew when insects are scarce. In captivity Merck recommends roughly half the diet as a nectar-type food and the other half as calcium-dusted or gut-loaded insects (crickets, mealworms and similar) plus a formulated pellet, with fruit, vegetables and nuts kept under about 10%. Other vet guidance puts more weight on pellets, so follow a glider-savvy vet's plan. Calcium with vitamin D3 is usually added. Serve food in the evening on a raised platform, keep fresh water out at all times, and never give chocolate, caffeine, candy, fruit pits or raw meat.5892

Company who they like around

Very high. Wild gliders live in family colonies of up to about seven adults plus young (Merck gives 5-12). Pets do best in pairs or small groups, for example one male with several females. A glider kept on its own needs at least one to two hours of close interaction every day. New gliders should be introduced carefully, because group members recognise each other by shared scent.25896

The story where it all began

George Robert Waterhouse named the sugar glider Petaurus breviceps in 1839, a Latin name that roughly means 'short-headed rope-dancer', a nod to its acrobatics in the treetops. The English name comes from its love of sweet foods such as sap and nectar and from its gliding. For a long time it was treated as one widespread species with several subspecies across Australia and New Guinea. A 2020 genetic study showed it was really several look-alike species: Krefft's glider across much of eastern Australia, the savanna glider in the north, and the sugar glider proper in a narrow coastal strip of south-east Queensland and New South Wales. Sugar gliders arrived in the US exotic pet trade in the 1990s, supplied through licensed breeding farms in Jakarta with founders from the Sorong area of West Papua. DNA work in 2019 and 2025 confirmed that pet gliders in the USA and Europe descend from this New Guinean stock, so most 'sugar gliders' in homes are technically a close relative of the Australian animal that carries the name. They have become a well-known pocket pet in North America and are kept in Europe too, while within Australia keeping them as pets is allowed only in some states and territories.234

Recognised by the official bits

IUCN Red List

Wild species listed as Least Concern.1

Taxonomy

Described by Waterhouse in 1839. A 2020 genetic study split the former species into three: Krefft's glider (P. notatus), the savanna glider (P. ariel) and the sugar glider in the strict sense (P. breviceps). There is no breed registry; pet gliders are a wild species kept in captivity.2

Campbell et al. 2019, PeerJ

Mitochondrial DNA showed that sampled US pet sugar gliders all came from West Papua, Indonesia, clustering with animals from the Sorong area.3

Mulko et al. 2025, Scientific Reports

Captive gliders bred in Europe and the USA grouped with the New Guinean lineage and were assigned to Petaurus papuanus rather than P. breviceps.4
