Sugar Glider Cage Setup: Tall, Not Wide

Sugar gliders are arboreal, and their housing needs reflect that directly, height matters far more here than floor space does, the opposite priority from a lot of small mammal setups.

Cage Size

The recommended minimum is 36 inches wide, 24 inches deep and 36 inches tall, and it has to hold two, since a glider should not live alone. Any space beyond that belongs in height. This is a climbing, gliding animal, and a cage that's wide but short doesn't suit how it moves the way a tall enclosure does. A double-unit multi-level cage at 36 by 24 inches and 63 inches tall clears that minimum with height to spare, and its levels and ramps give a climbing, gliding pair room to move.

Bar Spacing

Keep it to no more than half an inch. Young gliders are small enough to squeeze through wider gaps, and escape-proofing matters more with this species than the cage's overall size might suggest.

Temperature

75 to 88°F is the comfortable range. Keep the cage away from drafts and direct sun, and place it in a consistently warm part of the house rather than somewhere temperature fluctuates a lot through the day. A house that runs below about 75°F needs supplemental heat, a heat lamp or ceramic heat emitter, which puts a glider closer to a reptile's setup than to the rodents and rabbits a comfortable room already suits.

Humidity and Lighting

No special humidity control is needed for this species. Ordinary household lighting is sufficient, there's no UVB requirement the way many reptiles have, a bearded dragon setup, for comparison, genuinely can't skip that step the way a glider's can.

Substrate

A solid cage bottom with washable liners or trays underneath the main living area works best, rather than loose bedding that accumulates waste and becomes harder to keep clean.

The Non-Obvious Requirements

Position the sleeping pouch high in the cage, matching this species' natural preference for elevated, secure resting spots. A bonding pouch doubles as this resting spot and is also the starting point for taming. A hideout positioned nearby gives your pair another secure, elevated place to retreat to.

The Wheel

A wheel belongs in the setup. Gliding from high perches to low ones gives a glider much of its exercise, but a wheel matters as much to its physical and mental health. The running surface has to be smooth and unbroken, with no wire rungs for toes to catch in, and it has to be a wheel built for gliders. A standard rodent wheel can trap the long tail, and the center axle on many of them is the bigger danger. The same rung-free rule applies to a hedgehog's wheel, where wire and mesh injure the feet and legs of an animal that runs long distances every night.

Cover part of the cage with fleece, over the top, back, and sides. This isn't just decoration, it helps a new or still-bonding glider feel more secure, and supports the taming process.

Branches, Bedding and Headroom

Branches give a glider the climbing its body is built for, but the wood matters. Apple and pesticide-free, untreated citrus branches are safe choices. Almond, apricot, black walnut, cherry and peach are toxic to gliders and stay out. Bake any branch cut outdoors at 200 to 250°F for at least 30 minutes before it goes in the cage, to kill anything living on it. Horizontal bars and shelves help too, since vertical-only bars are hard for a glider to climb.

Under the cage, use shredded paper, paper towels, recycled paper pellets or aspen shavings. Pine and other softwood shavings give off oils that irritate a glider's airways, and cotton bedding sheds fibers that can wrap around a toe and cut off its circulation. If the nest box or pouch hangs high, leave enough room above it that a glider's elbows do not rub the cage roof, since that rubbing can tear the gliding membrane.

Cleaning Schedule

Set the food and water dishes away from the branches, where fewer droppings land in them. After that, the routine runs on two clocks.

• Every day: wash the food and water dishes with dish soap and water, and scrub the water bottle spout. Take out uneaten fresh food within about 4 hours. Spot-clean droppings, urine-soaked bedding and scattered food from the tray and floor.
• Every week: a full clean while the gliders are out of the cage, using a nontoxic cleaner, then rinse and dry everything before the bedding goes back in. Clean the nest box and wash the fleece pouches.
• At every clean: check fabric pouches for loose threads and replace any that have started to fray, since a loose string can wrap a toe or be swallowed.

Move the gliders to another room while spraying any household cleaner near the cage, and keep scented products away from the cage between cleans. A glider cage that still smells after a weekly clean usually points at the diet: heavy servings of protein, meat, insects and sugar are what make a glider smell.
