Taking Care of Your Degu

The degu (Octodon Degus) is native to the western foothills of the Andes. It is the most prolific mammal in Chile, where it is considered an agricultural pest. Since their importation into the US in 1964, degus have become a popular subject of research in the areas of diabetes, cataracts, and circadian behavior. Studies have shown that degus are social, long-lived and have a low incidence of disease, traits that make them outstanding pets.

Average lifespan: 5-8 years

Maximum lifespan: 10 years

Age sexual maturity: 3-4 months

Breeding season: year-round

Gestation: 87-93 days

Litter size: 1-10 pups

Weaning: 4-6 weeks

Litters per year: 2-3


Degus are rodents belonging to the suborder Hystricognathi (“porcupine-like rodents”) based upon jaw musculature and skull structure. They belong to the family Octodontidae. Octodon refers to the “figure 8” shape of their cheek teeth. Other names for the degu include brush-tailed rat and trumpet-tailed rat.


Degus resemble large gerbils and are dark grayish-brown with a dark brush on the tip of the tail. Their pupils are elliptical. The kidneys produce urine that is normally yellow and thick. They have five toes on each foot.


Degus are diurnal and do not hibernate. They dig elaborate burrows, are highly social and communicate via vocalization and postures. If degus are not given social interaction and physical stimuli, they may become aggressive or self-mutilate. Fighting is rare even when new introductions occur. They enjoy human interaction.


Degus should be provided with a large cage containing shelves, branches, a running wheel and plenty of room to exercise. Wood shavings, recycled paper products and hay are all suitable bedding materials. A dust bath should be provided as for chinchillas. At least two degus should be housed together.


Diet in the wild includes a wide variety of plants, roots, seeds, fruit and livestock droppings. A successful captive diet consists of a mixture of rodent blocks and guinea pig chow along with grass hay. Carrots, sweet potatoes, other vegetables, seeds and peanuts are given as treats. Foods containing sugar (e.g. fruits, raisins, breakfast cereal, honey treat sticks) should be avoided. Note that most pelleted feeds contain molasses, which is used as a binder. Starchy foods may also pose a risk.

Annual Checkup

A complete physical examination, review of diet and husbandry and fecal analysis are recommended on an annual basis.

Methods of Restraint

Degus are usually scooped up with two hands. They may be scruffed or held in an encircling grip for examination. Grasping by the tail should be avoided, as tail degloving easily occurs requiring amputation of the tail. Degus readily learn to step into a net, so this method can also be used.

Editors note: tail degloving involves stripping of the skin of the tail away from the muscle and bone of the tail.


Degus reach puberty at a later age than many rodents. Breeding should begin when the female is 4-9 months of age and body weight is below 250 g. In spite of their long gestation, degus are not born as fully developed as one would expect. The young are born with sparse fur and their eyes open around day 3. both parents huddle over the litter to keep them warm. The pups lie on their backs to suckle while the mother lies on top of them. Pups nurse for about 25 minutes. Male degus participate in raising the pups, so the pair must stay together for successful breeding to take place.
