Overview
- Degus are small, highly social rodents from the Chilean highlands, related to chinchillas and guinea pigs.
- Unlike most pet rodents they are diurnal, so they are active during the day.
- They are intelligent, vocal, and curious, using a rich repertoire of calls.
- They are obligately social and suffer if kept alone, so they must always live with at least one compatible degu.
- Their long lifespan and special dietary needs make them a serious commitment for an attentive owner.
Housing
- Provide a tall, multi-level metal cage of at least 90x60x60cm for a pair, larger for groups, with narrow bar spacing and solid (not wire) platforms.
- Degus are powerful chewers and diggers, so avoid plastic, which they destroy and may ingest.
- Include a deep digging area, hides, and platforms for climbing.
- They need a dust bath several times a week to keep their coat in good condition, plus a large solid running wheel.
- Keep the cage out of direct sun and below about 26C, as they are heat-sensitive.
- Provide constant safe chew material.
Diet
- Degus are strict herbivores that cannot process sugar properly and are prone to diabetes, so their diet must be low in sugar and starch and very high in fibre.
- The foundation is unlimited grass hay, supplemented with a small amount of degu- or chinchilla-appropriate pellets and fresh leafy greens.
- Never feed fruit, carrots, sweet vegetables, or sugary treats, and avoid sugary commercial rodent mixes.
- Constant fresh water and unlimited hay support both their teeth and gut.
- Safe gnawing wood helps wear their continuously growing teeth.
Health
- Diabetes is the signature degu disease, linked to sugary diets and causing cataracts and weight loss.
- Their teeth grow continuously and can overgrow or develop painful malocclusion without enough hay and gnawing material.
- Cataracts, bumblefoot, and tail-skin injuries are also common.
- Never pick a degu up by the tail; the skin can slough off ("tail degloving"), after which the bare bone is amputated.
- Cloudy eyes, weight loss, excessive drinking, or drooling all warrant a prompt exotic-vet visit.
Temperament
- Degus are bright, busy, and playful, forming strong bonds within their group and grooming and "talking" to one another constantly.
- With gentle, frequent handling from a young age they become tame and interactive, often climbing onto trusted owners and learning simple routines.
- They are fast and can be nippy if startled or rough-handled, so calm consistency works best.
- Their daytime activity makes them more interactive than nocturnal rodents, but a lone degu becomes stressed and unhealthy.
A good fit for
- Owners wanting an active, daytime rodent
- Keepers who can house a bonded pair or group
- People committed to a strict sugar-free diet
- Those wanting a long-lived, intelligent small pet
Common mistakes to avoid
- Keeping a single degu alone
- Feeding fruit, carrots, or sugary mixes (diabetes)
- Lifting by the tail (causes degloving)
- Plastic cages and accessories they chew and ingest
Is your enclosure big enough?
Is this urgent?
Small mammals are prey animals. They mask pain and illness by instinct, so by the time something is obvious it is usually already advanced.

Have the number of an exotics-competent practice saved before you need it. Most general small-animal clinics do not treat rabbits or rodents out of hours, and finding one at 11pm is not realistic.
This is general guidance for a healthy adult, not a diagnosis. An exotics vet who knows your animal always overrides it — and the time to find one is before you need one.
Can a degu eat that?
Most small companion mammals are hindgut fermenters: the gut is a fermentation vessel that has to keep moving, and sudden rich food stops it.

Everyday foods (6)
That food is not on our list. Do not offer it on a guess — check with an exotics vet, or leave it out. Nothing in a small mammal's diet is urgent enough to risk it.
Introduce any new food one at a time, in a small amount, and wait two days before adding another. A change in droppings is the earliest signal that something did not suit.
What it really costs
Setup, monthly, first year and across a whole life, itemised and with the electricity worked out from the actual wattage. Published figures for the same animal disagree by a factor of four, so the calculator shows ranges rather than picking one.
