Sugar Glider
Petaurus breviceps
The nocturnal marsupial that bonds hard and lives in a colony — a demanding, long-term exotic with a diet you don’t improvise.
Difficulty: AdvancedPrintable care sheet →
Sugar gliders are tiny nocturnal marsupials — not rodents — that glide between trees on a membrane stretched from wrist to ankle, live in bonded colonies, and can share 12–15 years with a committed owner. They’re also one of the most mis-sold pets there is: they’re demanding, long-lived, intensely social, and need a specialist diet that is genuinely hard to get right. This is the honest guide — including whether you can legally, and realistically, keep one.
Wild sugar gliders live in large social groups called colonies and fare better in captivity when housed in pairs or small groups.
Care at a glance
| Adult size | Small — females weigh about 80–135 g and males about 100–160 g — a palm-sized body with large eyes, a long tail used as a rudder, and the gliding membrane along each side. |
|---|---|
| Lifespan | Long for such a small animal — around 4–15 years, often reaching 12 or more with good care. This is a decade-plus commitment. |
| Enclosure | A large, secure, TALL cage of PVC- or powder-coated wire — a recommended minimum of about 61 × 91 × 91 cm (24 × 36 × 36 in), and bigger is better — with bar spacing no wider than about 2.5 × 1.3 cm. Height matters because gliders climb and glide. Provide a nest box or sleeping pouch placed high, with enough clearance above it that their elbows don’t rub the roof (which can tear the gliding membrane), plus safe climbing branches (never almond, apricot, black walnut, cherry or peach wood; apple or untreated citrus is safer, baked first) and a solid, smooth-interior exercise wheel that can’t trap toes. Keep the cage out of direct sun and away from vents. |
| Companionship | Sugar gliders are colony animals and should never be kept singly — in the wild they live in groups of many individuals, and in captivity they do best in pairs or small groups (for example one male with several females). A glider kept alone needs an enormous amount of daily attention and can otherwise become stressed and self-mutilate. |
| Temperature | They tolerate roughly 15–32°C but prefer a warm 27–31°C; keep the cage away from draughts, vents and direct sun. If they get too cold they can drop into torpor to conserve energy, so steady warmth matters. |
| Bedding & substrate | Line the cage bottom (or its droppings tray) with newspaper or another recycled-paper product that’s non-toxic if nibbled. The important “home” feature is a cosy nest box or fabric sleeping pouch high in the cage for daytime sleeping. |
| Enrichment & exercise | Gliders are athletic climbers and need a lot to do: branches, ropes, sleeping pouches, foraging opportunities, and a safe smooth-surface wheel. Daily supervised interaction and time out of the cage reduces boredom and builds the bond — but never leave a glider out unsupervised, as they’re easily injured. |
| Grooming & upkeep | Sugar gliders groom themselves (a fused toe on each hind foot acts as a grooming comb) and need little from you. Postpubescent males have scent glands that leave a normal bald patch on the forehead and chest and a musky odour — that’s not a health problem. Check nails, and let a glider vet handle anything more involved. |
| Diet | This is the hardest part of glider care, and where most go wrong. About half the diet should be an artificial nectar (a formulated “Leadbeater’s”/BML-type mixture); the rest should be a mix of a commercial glider pellet, gut-loaded or calcium-dusted live insects (crickets, mealworms) for protein, with only a small amount of fruit and vegetables (together under about 10% of the diet). Feed twice a day with fresh water always available. Because their natural sap-and-insect diet is so hard to replicate, a vet experienced with sugar gliders should set the exact plan and supplement schedule. |
| Supplements | Calcium with vitamin D3 is essential — a poor, fruit-heavy diet without balanced calcium causes metabolic bone disease. Gut-load or dust feeder insects with calcium, and follow a glider vet’s supplement schedule. |

What it's like to live with a Sugar Glider
Life with sugar gliders happens after dark: they sleep bundled in a pouch all day, then wake to climb, glide, forage and “crab” (a loud buzzing complaint) at night. They bond intensely — to each other and, slowly, to a patient owner who carries them in a bonding pouch — but that bond is a responsibility, not a novelty. Everything about them is long-term and specific: the colony, the diet, the tall cage, the nightly attention. Rush any of it and you get a stressed, sick animal; do it properly and you get a genuinely extraordinary companion for over a decade.
Your first month together
The settling-in period, in order — so you know what's normal and when not to worry.
- Before anything, confirm it’s legal where you live and line up a vet experienced with sugar gliders.
- Set up a tall cage with a high sleeping pouch, safe branches and a smooth wheel, kept warm (27–31°C).
- Sort the specialist diet in advance — nectar, glider pellet, gut-loaded insects, and calcium/D3 — with vet guidance.
- Get at least two (they’re a colony), and bond slowly using scent and a bonding pouch; expect crabbing at first.
- Give nightly supervised interaction, and learn their normal so you can spot the early signs of bone or dental disease.
Through the year, and as they grow
Keep them warm year-round so they don’t drop into torpor in cold spells. The constant, non-negotiable job is the diet and its calcium balance — watch closely for any hind-leg weakness or tremors that can signal metabolic bone disease, and get veterinary help early.
The pet store gets these wrong
Common myths, kindly corrected — no shame for having believed them.
- Sugar gliders are marsupials, not rodents — and they need care to match, not rodent care.
- They can’t live alone. They’re colony animals; a solitary glider often becomes stressed and can self-mutilate.
- A fruit-and-nectar-only diet is dangerous. Without balanced protein and calcium they develop crippling metabolic bone disease.
- A small cage won’t do — gliders need a tall cage to climb and glide.
- They’re not a cheap impulse pet — expect 12–15 years, a specialist diet, and an exotic vet.
- They’re not legal everywhere — check your local laws before considering one.
Before you buy
- Is it legal to keep a sugar glider where you live?
- Are you ready for a 12–15 year commitment to a colony (never just one)?
- Can you source and fund the specialist nectar/insect/calcium diet — and a glider-experienced vet?
- Can you provide a tall cage, warmth (27–31°C), and nightly interaction with a nocturnal animal?
- Do you accept that their diet can’t be improvised, and getting it wrong causes fatal bone disease?
See a vet if…
We can't diagnose from afar — but these are the signs to stop watching and get a professional:
- Weak, dragging or paralysed hind legs, muscle tremors, unexplained fractures, or seizures — signs of metabolic bone disease from a calcium-deficient diet; see a glider vet
- Not eating, weight loss or lethargy
- Self-barbering, over-grooming or self-inflicted wounds — often stress, especially in a lone glider
- Drooling or difficulty eating (dental disease, usually from a too-sugary diet)
- A cold, torpid, unresponsive glider — warm gradually and seek advice
- Diarrhoea or persistently soft droppings
Never
- Never keep a single sugar glider — they need colony company.
- Never feed a fruit- or sugar-heavy diet, or skip calcium and vitamin D3 — it causes fatal bone disease.
- Never use toxic branch woods (almond, apricot, black walnut, cherry, peach).
- Never use an open-rung wheel that can trap toes.
- Never let a glider roam unsupervised outside its cage.
- Never buy one without checking local legality and finding a glider-experienced vet first.
Common sugar glider questions
How hard are Sugar Gliders to keep — are they good for beginners?
Advanced. Not a beginner or impulse pet, despite being sold like one at mall kiosks. Sugar gliders are colony marsupials that live 12+ years, need a tall cage, nightly attention (they’re nocturnal), and a strict, specific diet you can’t improvise — get the diet wrong and they develop fatal bone disease. They’re also restricted or illegal in some places. Only for a dedicated, prepared owner.
What do Sugar Gliders eat?
This is the hardest part of glider care, and where most go wrong. About half the diet should be an artificial nectar (a formulated “Leadbeater’s”/BML-type mixture); the rest should be a mix of a commercial glider pellet, gut-loaded or calcium-dusted live insects (crickets, mealworms) for protein, with only a small amount of fruit and vegetables (together under about 10% of the diet). Feed twice a day with fresh water always available. Because their natural sap-and-insect diet is so hard to replicate, a vet experienced with sugar gliders should set the exact plan and supplement schedule.
How big an enclosure do Sugar Gliders need?
A large, secure, TALL cage of PVC- or powder-coated wire — a recommended minimum of about 61 × 91 × 91 cm (24 × 36 × 36 in), and bigger is better — with bar spacing no wider than about 2.5 × 1.3 cm.

Keep the cage out of direct sun and away from vents.
Do Sugar Gliders need a companion, or can they live alone?
Sugar gliders are colony animals and should never be kept singly — in the wild they live in groups of many individuals, and in captivity they do best in pairs or small groups (for example one male with several females). A glider kept alone needs an enormous amount of daily attention and can otherwise become stressed and self-mutilate.

What are the signs Sugar Gliders are sick or need a vet?
See a small-animal or exotics vet if you notice: Weak, dragging or paralysed hind legs, muscle tremors, unexplained fractures, or seizures — signs of metabolic bone disease from a calcium-deficient diet; see a glider vet; Not eating, weight loss or lethargy; Self-barbering, over-grooming or self-inflicted wounds — often stress, especially in a lone glider; Drooling or difficulty eating (dental disease, usually from a too-sugary diet); A cold, torpid, unresponsive glider — warm gradually and seek advice; Diarrhoea or persistently soft droppings.
