Milder weather may make an outdoor outing appealing: degus can explore a new environment and encounter fresh plants. However, an outdoor session is optional enrichment, and requires careful planning. Protection from escape, predators, unsuitable weather and unfamiliar foods matters more than the novelty of being outside. A supervised indoor playpen offers a separate option.
Before an outdoor outing
- Assess the individual and the weather. An indoor animal is not automatically adapted to outdoor temperature changes. Consider health, age and the actual conditions inside the pen. Opening a window does not certify acclimatisation, and the cage must remain protected from draughts, direct sun and escape.
- Prepare for fresh vegetation. Introduce suitable fresh plants gradually as part of the normal diet before allowing grazing. If the animal is not accustomed to them, prevent uncontrolled access to vegetation and provide only identified plants in appropriate quantities.
- Secure the site. The enclosure must resist escape and access by other animals, including through the roof and beneath its edges. Mesh spacing must suit the smallest degu.
- Identify every accessible plant. Remove toxic or unidentified plants and avoid pesticide-treated or otherwise contaminated ground. See our edible-plant guide and plants and foods to avoid.
- Provide shade, water and shelter throughout. Check that the shaded area remains shaded as the sun moves.
- Plan a prompt return indoors. Keep a suitable carrier ready, and know how to bring the animals back without chasing or grabbing them.
Weather and temperature
Choose mild, dry, calm conditions and avoid the hottest part of the day. Degus are vulnerable to heat illness. Direct sun can overheat a pen or shelter even when the reported air temperature seems moderate. Rain, damp bedding, strong wind and abrupt temperature changes also require attention.
The earlier article quoted an outdoor range of 1–24°C and a maximum tolerance of 32°C. These figures must not be treated as a universally safe range or permission to expose an indoor pet to near-freezing conditions or 32°C heat. The RSPCA advises keeping the enclosure no warmer than 20°C. Assess the enclosure itself, the animal and its ability to retreat, rather than relying on a single threshold.
Wild degus adjust the timing of surface activity and can retreat into burrows, which buffer outdoor conditions. A pet in a pen may have neither the same acclimatisation nor an equivalent refuge. A general statement that every wild burrow remains at 22–24°C, or that captive animals are necessarily better adapted to temperature changes, is too broad.
If you use an open window to familiarise the animals with outdoor sounds, keep it securely screened and avoid chilling, draughts or direct sunlight. Stop the outing if conditions deteriorate or the animal shows distress; do not wait for a numerical temperature limit.
Preventing escape and predator access
Degus are prey animals, and an escaped pet may be injured, lost or expose local wildlife to risks. An uncovered exercise pen is insufficient outdoors. Cats, dogs and birds must not have access, and strong fine mesh is needed to reduce the risk of bites or claws reaching through.
Place the closed carrier inside the secured enclosure before opening it, then secure the enclosure before allowing exploration. Do not transfer animals across an open gap. Active supervision is required throughout a temporary outing.
Prevent digging beneath the boundary. An underground anti-dig barrier or another secure base must not leave the animals standing on exposed wire: provide a safe, solid or suitably covered walking surface. A roof is needed against climbing escapes and overhead predators. A standard rabbit pen or bird aviary is not automatically suitable without checking every gap, joint and access point.
A harness is not recommended. A degu may slip out or injure itself while struggling, and a lead provides no protection from predators.
The original article illustrated this point with a rabbit enclosure credited to Zooland Animalerie. That external illustration is no longer available. A rabbit enclosure would require assessment and adaptation for degus; the former illustration was not a product-safety endorsement.
Furnishing the enclosure
Provide clean drinking water, a cool shaded area and several secure retreats. Stable stones, tunnels and suitable bark can offer exploration and cover, provided they cannot collapse, trap the animals or introduce toxic materials. Maintain useful ground space as well as safe opportunities to climb. See our housing guide and enrichment guide.
The first outings
Assemble and inspect the enclosure before bringing the animals outside. Allow them to leave a familiar carrier voluntarily, with somewhere to hide. Practise returning to the carrier beforehand; a suitable small food reward can help, but should not replace safe enclosure design.
Watch behaviour closely. Persistent hiding, freezing, agitation or attempts to escape suggest that the session should end. Exploration, observation and eating can be reassuring, but do not prove that all risks have been removed.
Keep early sessions brief and adapt to the individual. The previous suggestion of 15–20 minutes was a practical example, not a validated minimum or a target to complete. End sooner whenever needed. Increase duration only if the animal is comfortable and conditions remain suitable.
Longer-term outdoor accommodation
Seasonal outdoor housing is a more demanding project than a short supervised outing. It should not be inferred to be safe merely because degus live outdoors in Chile. Discuss the individual animals and local climate with a knowledgeable vet, and keep suitable indoor accommodation available.
Plan for daytime heat, cold nights, damp, frost and sudden changes. Bring the animals indoors before conditions become unsuitable; waiting until the first frost is not an adequate general rule. A gradual transition cannot guarantee successful adaptation.
The enclosure needs a strong roof, secure doors and preferably an entrance vestibule, chew-resistant boundaries and an effective anti-dig base. Adequate ground area is essential, but degus also use branches and other climbing structures. Select the design for these needs rather than simply buying an aviary marketed for terrestrial birds.
Insulated retreats or a carefully designed artificial burrow can buffer conditions, but an underground metal box is not automatically safe. Consider drainage, ventilation, condensation, flooding, temperature extremes, access for inspection and a way to retrieve an ill animal. Use temperature probes at animal level, including inside shelters, day and night.
Provide water, hay and the normal balanced daily ration even where edible plants grow. A degu garden can provide vegetation only if all plants and growing conditions are safe. Include secure hiding places and appropriate exercise opportunities. A wheel needs a solid running surface and sufficient diameter; plastic is not inherently preferable, particularly if chewed. Provide a suitable sand bath at appropriate intervals and keep it dry.

Keep the enclosure away from areas contaminated by dog or cat faeces. Ask the vet about parasite risk, examination and testing where indicated. Outdoor access does not justify routine, identical deworming of every species in the household; parasite control must be appropriate to the species, exposure and diagnosis.
Inspect the structure and animals frequently. Rats, weasels, foxes and other animals may exploit small defects, and illness can develop despite careful planning. Bring the degus inside whenever a concern arises, investigate it and repair the enclosure before considering further use.
