📌 Description

Octodon degus is a non-venomous small mammal with care needs shaped by its natural habitat: dry open scrubland with burrows, rocks, grasses, roots, and strong day-night rhythm. Adults are usually around 170-310 g adult body weight, and a realistic captive lifespan is 5-8 years, sometimes longer when housing, diet, and veterinary care are handled well.

This is not an impulse animal. The enclosure has to be planned around adult size, daily maintenance, heat and humidity measurement, and the keeper’s ability to notice stress before it turns into disease. Captive-bred animals from transparent sources are strongly preferable, especially for species that have a history of wild collection.

The most useful care mindset is to build choices into the enclosure. The animal should be able to warm up, cool down, hide, drink, feed, and move without being forced into constant exposure.

🌍 Distribution

Octodon degus is native to dry scrub, matorral, rocky slopes, and agricultural edges in central Chile. In nature it is associated with dry open scrubland with burrows, rocks, grasses, roots, and strong day-night rhythm. That distribution should be read as a care clue rather than copied as one fixed number: the animal uses shade, cover, burrows, vegetation, water, season, and daily movement to choose suitable microclimates.

For captive care, the useful lessons are:

• secure retreats and visual cover
• a measured thermal gradient instead of one uniform temperature
• humidity that matches the species without stagnant wet air
• clean water and predictable hygiene
• enough usable space for normal movement

⚖️ Legal status

As checked against current CITES Appendices, Species+ references, and EU wildlife-trade context in May 2026, no current CITES listing or species-specific EU wildlife trade Annex listing was found for Octodon degus. It is not relevant to the Bern Convention because it is not native to Europe. National and local rules on import, sale, breeding, transport, animal welfare, and proof of legal origin may still apply, so keep clear purchase and veterinary records.

🤌 Husbandry

Plan for a large chew-proof enclosure for a stable same-sex social group, ideally 120 x 60 x 100 cm or larger with shelves and deep digging space. Temporary introduction or hospital cages can help with monitoring, but permanent housing still needs dry bedding, water, cover, chew-safe shelves, ventilation, and enough complexity that animals can avoid conflict. Bare oversized enclosures often make new animals defensive or inactive; clutter and sight breaks make space usable.

Keep compatible degus in stable groups, quarantine newcomers, and provide enough feeding points, nest boxes, tunnels, and shelves to prevent bullying. Daily checks should include water, waste, locks, temperature, humidity, appetite, coat and skin condition, teeth, feet, and behaviour.

Use digital thermometers and hygrometers rather than guessing. Record feeding, weight, coat condition, dental wear, cleaning, group changes, and veterinary issues. A simple log makes gradual weight gain, tooth problems, and early illness much easier to interpret.

💡 Lighting

Provide a clear day-night rhythm for this diurnal rodent. Degus do not need UVB, but they do need bright daytime room light, shaded retreats, and true darkness at night. No visible night lights should shine into the enclosure.

Keep the enclosure out of direct unfiltered sun, because a cage can overheat quickly. Any room light or cage-safe fixture should sit outside chewing reach, with cables protected from gnawing.

🌡 Heating and temperature

Practical temperature targets: room range 18-24 °C, avoid sustained heat above 26 °C, provide cooler retreats, and do not force a basking spot. These values should create a gradient, not a single average. Measure shelves, nest areas, and ambient zones with reliable thermometers.

Every heat source must be controlled by a thermostat where appropriate and protected from chewing. Avoid heat rocks, unguarded bulbs, and enclosed hot spots. If degus pant, stretch out, avoid parts of the cage, refuse food, fight more than usual, or stay hidden for days, verify the actual temperatures before changing diet or handling.

💧 Humidity and water

Target humidity and water management: normal dry indoor humidity with dust-free bedding and constant fresh water. Humidity should be paired with ventilation. Constantly wet, dirty air encourages respiratory and skin problems, while very dry dusty bedding can irritate eyes, nose, and feet.

Offer water in a heavy bowl, a bottle, or both, and check bottle sippers every day because blocked tubes can dehydrate a group quickly. Keep bedding dry around water points and clean wet areas before they smell.

🌿 Enclosure and decoration

The enclosure should be functional first and attractive second. Use secure nest boxes, tunnels, chew-safe branches, cork, untreated wooden shelves, a solid running wheel, a sand bath, safe digging areas, and enough visual barriers that the group can move without feeling exposed. Heavy furnishings must not collapse or trap feet.

Bedding should support digging and stay clean. Avoid dusty bedding, sharp decor, sticky tape inside the enclosure, unstable rocks, fabrics that fray into threads, and small loose items that could be swallowed. Doors, vents, cable ports, and lids must be escape-proof and chew-resistant.

🪳 Feeding

Feed a varied, species-appropriate diet: high-fiber hay, safe dried herbs, low-sugar rodent pellets, branches for chewing, and very limited treats. Young animals usually need smaller and more frequent meals; adults need body-condition-based feeding rather than food every time they appear interested. Overfeeding is as real a welfare problem as underfeeding.

Keep the diet high in fiber and very low in sugar. Do not add fruit, honey sticks, sweet seed mixes, fatty treats, or insect prey as routine food. Remove uneaten fresh items before they spoil and watch body condition rather than feeding every time the group begs.

🩺 Common problems

Common problems include diabetes risk from sugary food, dental overgrowth, bumblefoot, respiratory irritation from dusty bedding, obesity, heat stress, and social stress. Warning signs include weight loss, repeated refusal to eat, drooling or a wet chin, uneven tooth wear, weak grip or poor movement, wheezing, nasal discharge, swollen eyes, foot sores, mouth injury, burns, diarrhoea, or unusual aggression from an otherwise settled animal.

When something looks wrong, first verify the basics with instruments: warm zone, cool zone, night temperature, humidity, water access, hide fit, diet, dental wear, group dynamics, and recent stress. Serious weakness, injury, breathing signs, dental pain, neurological signs, or rapid decline need an experienced exotic-animal veterinarian.

📌 Conclusion

Octodon degus can be kept responsibly when the keeper plans for the adult animal and treats legal origin, measured climate, suitable diet, and veterinary access as part of the setup. The best enclosure is not the most decorative one; it is the one that gives the animal safe choices every day.
