Degu

Overview

The degu (Octodon degus) is a diurnal social rodent native to Chile - an unusual pet choice that combines daytime activity (rare in small pets), strong social bonds, and an intelligent curious temperament. Degus are increasingly popular but require specific care, particularly a very low-sugar diet to prevent diabetes.

Natural History & Origin

Wild degus inhabit central Chile's open scrubland. They live in extended family groups in elaborate burrow systems. Active during the day (diurnal), eat grasses and shrubs, communicate with a wide vocabulary of vocalisations.

Appearance

Adults weigh 170-300 g, body length 12-18 cm plus tufted tail.

Coat: agouti (wild), with a tan belly. Genetic colour varieties include blue and "pied" (white markings) but most pet degus are wild-type colour.

Temperament & Handling

Active, social, intelligent. Degus bond closely with their group (degu and human). They are diurnal, so active during human waking hours - unlike most small mammals.

Handle gently and never by the tail - the tail tip can break off and never regrows.

Housing

Minimum enclosure: 1 × 0.5 × 1.5 m tall, larger for more degus. Multi-level wire cages with solid platforms (similar to chinchilla housing). Keep the enclosure no warmer than 20°C so the degus do not overheat (RSPCA).

Provide:

• Wooden chew toys.
• Hideouts.
• Solid wheel (30+ cm: degus need very large wheels).
• Sand bath (chinchilla sand, similar care to chinchillas).
• Heavy ceramic bowls and water bottle.
• Climbing branches.

Diet

Critical: degus are highly prone to diabetes and develop it quickly with sugar.

• Chinchilla pellets (plain, no fruit) as staple.
• Unlimited grass hay (timothy).
• Daily fresh greens - small amount of vegetables; avoid sugary ones.
• No fruit, no sweetened treats, no carrots.
• Limited seeds.

Diabetes in degus is often fatal and is preventable with strict diet control.

Health & Lifespan

Typically 6-7 years in captivity, according to the RSPCA.

Common concerns:

• Diabetes - extremely common with improper diet; often fatal.
• Dental disease (malocclusion).
• Cataracts.
• Tail injuries.
• Bumblefoot.

Social Needs

Highly social. Always keep at least same-sex pairs (preferably 3-4 from the same family). Lone degus are depressed and short-lived.

Adult degu introductions are difficult - best with same-litter siblings.

Pros & Cons

Pros:

• Diurnal: active when humans are.
• Highly intelligent and social.
• Long-lived for size.
• Bond strongly with humans.
• Engaging to observe.

Cons:

• Must be kept in groups.
• Diabetes risk requires strict diet.
• Large enclosure needed.
• Uncommon: vet expertise variable.
• Tail injury risk.

Best Suited For

• Owners wanting a daytime-active small pet.
• Multi-degu households.
• Adults and older children.

Not suited for households unwilling to keep groups, or those unable to maintain strict diabetes-prevention diet.
