Degu
Small Mammals
The daytime rodent that cannot eat sugar and will not live alone!
On This Page▾
🤓 Did you know? Degus are one of the few mammals that cannot metabolize dietary sugar properly. They have an unusual insulin structure and develop diabetes and cataracts on a diet most other rodents handle fine, which is why a single grape can matter here in a way it never would for a hamster.
🗓️ The first week
The numbers a new owner needs in the first week, each from the article it links to. Rows with no link come from the encyclopedia.
- Legal
- Restricted in fifteen jurisdictions and banned outright in eight, the most regulated of the small rodents sold as pets.Legal guide →
- Never one
- Two minimum, same-sex or neutered, ideally littermates. Isolation is linked to aggression and self-mutilation, a stronger statement than for most rodents.Enrichment guide →
- The cage
- About 28 by 18 by 28 inches minimum for a pair, tall and multi-level, in metal with bar spacing no more than half an inch. Solid shelves, not wire. Not a fish tank or glass vivarium: they cannot breathe in one.Setup guide →
- Solid roof
- Their wild predators are birds of prey, so movement overhead frightens them. A solid roof rather than open mesh.Setup guide →
- Temperature
- Cool, 65 to 70°F, and never toward 77°F. Away from windows, radiators, and direct sun.Setup guide →
- Substrate and wheel
- Dust-free aspen or paper bedding with a deep digging area. A solid wheel of 11 to 12 inches; wire wheels catch toes and a small one arches the spine.Setup guide →
- Sand, not dust
- Bathing sand two or three times a week, twenty minutes at a time, sifted and topped up rather than left in. The enrichment guide says sand, not chinchilla dust; the cost guide prices dust, and this card follows the enrichment guide.Enrichment guide →
- Chewing
- Mineral and lava blocks, untreated wood, cardboard, apple or willow branches. Anything plastic in the cage will be chewed eventually.Enrichment guide →
- Hay
- Unlimited grass hay, timothy, meadow, or orchard, at all times. It is the bulk of the diet and what keeps the teeth worn down.Feeding guide →
- Pellets
- Measured, not free-fed: roughly 1 to 2 tablespoons per degu daily. Given the choice they eat pellets over hay and lose the fiber they need.Feeding guide →
- Sugar
- Fruit, honey, and any sugary treat avoided almost entirely. Degus develop diabetes so readily they are studied as a model for it.Feeding guide →
- Rabbit food
- Never. Rabbit pellets carry a coccidiostat that harms degus, and hamster and gerbil mixes are too high in protein and seed.Feeding guide →
- Orange teeth
- Healthy teeth look orange. White or pale teeth in an adult are the sign of a problem.Health guide →
- Never the tail
- The skin sloughs off under grasping pressure and does not grow back. Scoop by the body.Handling guide →
- Heat stress signs
- Rapid or open-mouth breathing, then drooling, then weakness, with tremors or collapse as the severe stage. Move it to the coolest room, cool it gradually, and get to a vet.Heat and cold guide →
- Budget
- $10 to $50 per degu and you need two. Equipment roughly $375 to $520, most of it a 24x24x48 inch multi-level cage at $280 to $360, and an exotic vet check with dental at $80 to $160 a year.Cost guide →
- Lifespan
- 5 to 8 years in captivity.Cost guide →
- Adult size
- 5 to 8 inches (12 to 20 cm) body, plus a 4 to 5 inch tufted tail; 6 to 11 oz.
🚨 Emergency card
Call the vet now if you see any of these.
- Rapid or open-mouth breathing, drooling, weakness, or collapse in a warm room: heatstroke, an emergency above about 77°F
- A sudden increase in drinking and urination, with weight change or cloudy eyes: diabetes, manageable if caught but never cured
- Labored breathing or nasal discharge
Book a vet visit promptly for these.
- Drooling or a wet chin, dropping food, weight loss, watery eyes: dental disease, usually filed under anesthesia
- Red, swollen, or scabbed footpads: switch to solid flooring now, and a vet if it is infected or not improving
- Persistent lethargy
An exotics-experienced vet, registered with before you need one, since degus are a newer pet species and the veterinary picture is still filling in.

❓ Frequently Asked Questions
Can I keep just one degu?
No. Degus are highly social and need to live in same-sex pairs or small groups. A solitary degu becomes stressed, which shows up as neurotic or aggressive behavior over time, the direct opposite of the solitary Syrian hamster, which must be housed alone.
Why are degus so prone to diabetes?
They're naturally insulin-resistant, with a genetic predisposition toward diabetes that most small mammals don't share. Even small amounts of fruit, carrot, peas, corn, or sugary treats can trigger the disease, and veterinary literature flags the species as one where that predisposition creates real, ongoing management challenges.
Does a degu need sand or dust for bathing?
A sand or dust bath two to three times a week supports healthy coat condition and is a real physiological need, not optional grooming. Bathing sand is generally the gentler, better-suited choice for degus specifically, finer chinchilla dust is a reasonable alternative but was formulated for chinchilla fur.
