🏠 Enclosure

• Enclosure planning dimensions: 150 x 90 x 180 cm

🪨 Substrate and furnishings

Furnish the full height with pesticide-free branches of different diameters, cork, ropes that cannot fray into loops, elevated shelves, foraging cups, and multiple sleeping boxes or seamless pouches. Leave some long diagonal and horizontal routes open for controlled leaps. Every group needs more sleeping and feeding options than dominant animals can monopolize.

Inspect fabric daily. Loose threads can constrict toes, trap claws, or injure the patagium. Avoid cotton wool, frayed rope, open-chain toys, galvanized or damaged coated wire, toxic timber, exposed fasteners, and wheels with center axles or crossbars. If a wheel is used, choose a large glider-safe design with a solid running surface and no pinch points.

💡 Lighting

Provide a predictable 10–12-hour light period followed by a genuinely dark night. Bright white or colored “night” lamps disrupt nocturnal behaviour; use a camera that does not emit visible light if observation is needed. Position the cage away from windows where direct sun can overheat sleeping pouches.

UVB is not established as a routine requirement for captive sugar gliders. Vitamin D and calcium must instead be managed within the chosen complete diet protocol. Do not add a UVB lamp or extra vitamin D as a substitute for correcting an unbalanced diet, and never combine supplement schedules from unrelated recipes.

🌡️ Temperature

Maintain most usable space at 22–27 °C, with cooler choices around 20–24 °C and night temperatures around 20–26 °C. Veterinary references give a thermoneutral zone of approximately 27–31 °C, but the enclosure must still offer cooler retreats and must not be uniformly heated. Healthy adults can tolerate a wider range briefly; tolerance is not a target.

If room heating is necessary, warm the room or use an inaccessible, thermostatically controlled source outside the cage. Never put a heat mat, unguarded lamp, hot rock, or chewable cable inside. Measure temperatures at sleeping pouches and high and low perches. Persistent torpor, cold extremities, panting, sprawling, unusual hiding, or reduced appetite requires an immediate instrument check and veterinary advice when it does not resolve promptly.

💧 Humidity and water

Aim for 50–70% relative humidity with continuous ventilation and dry sleeping material. Do not keep the cage wet to reach a number. Local humidity can be supported with room humidification or carefully placed moisture-retaining natural materials, while food residue and soaked bedding must be removed every morning.

Provide fresh water at all times. A bottle plus a stable elevated bowl gives redundancy, but both must be checked daily for blockage or contamination. Dehydration can progress quickly in a small sick marsupial; sunken eyes, tacky mouth tissues, weakness, or reduced urine are urgent signs.

🪳 Feeding

Choose one complete diet plan with an exotic-animal veterinarian and follow it accurately. No single homemade diet has proved ideal, and casually mixing nectar recipes, pellets, fruit, insects, and supplements makes calcium, phosphorus, protein, vitamin D, vitamin A, and iron intake impossible to judge.

A sound plan generally includes:

• a formulated sugar-glider staple or measured nectar/exudate substitute
• an appropriate protein component, often a formulated feed and calcium gut-loaded insects
• controlled portions of suitable vegetables and limited fruit rather than a fruit bowl
• calcium and vitamin supplementation only in the amounts built into that protocol
• fresh food placed on elevated feeding stations after dusk and removed in the morning

Offer several small feeding points so a dominant animal cannot guard the ration. Weigh portions and track each animal’s weight and body condition. Treat insects and fatty foods can rapidly drive obesity. Avoid chocolate, caffeine, alcohol, onion, garlic, avocado, fruit pits and seeds, raw meat or egg, dairy, sugary human food, and insects exposed to pesticides. Cat feces and raw meat are important toxoplasmosis risks.

🩺 Health — warning signs

Nutritional secondary hyperparathyroidism, often called metabolic bone disease, is a major preventable problem. Weak grip, tremors, painful movement, fractures, or hind-limb weakness can follow a calcium-poor or phosphorus-heavy diet. This is an emergency, not a reason to add calcium blindly at home.

Other concerns include obesity, dental disease, diarrhea, dehydration, respiratory infection, parasites, urinary or reproductive disease, patagium and toe injuries, and stress-related overgrooming or self-mutilation. A solitary animal that circles, repeatedly calls, chews itself, or becomes withdrawn needs both medical and social assessment.

Check every animal daily even when the colony shares one sleeping pouch. Rapid weight loss, failure to eat, labored breathing, persistent diarrhea, swelling, bleeding, dragging limbs, inability to climb, prolapsed tissue, or self-injury requires an exotic-animal veterinarian urgently.
