The degu is a small rodent native to the rocky slopes and scrublands of the Andes Mountains in Chile, where it lives in social groups of five to ten individuals. Its name for vocal complexity is well earned — degus are said to use more than fifteen distinct vocalizations, earning them the nickname "the singing mouse of the Andes." Adults typically measure 15 to 20 cm in body length and weigh between 170 and 350 grams, with soft grey-brown fur and expressive round eyes. Their high intelligence allows them to learn their names and even simple tricks, and individuals that are well socialized from a young age often enjoy sitting on a hand or shoulder. As diurnal animals, degus are naturally active during daytime hours, making them easier to bond with than nocturnal small pets. Their relatively quiet vocalizations also make them suitable for apartment living. Understanding their specific needs — regular dust baths, a sugar-free diet, and the companionship of at least one other degu — is the foundation of keeping them healthy and content.
1Keep Them in Pairs or Groups
Degus are highly social animals that naturally live in groups, and solitary housing can lead to stress and health issues. Keeping same-sex pairs or small groups is strongly recommended, especially for first-time owners considering their first degu.
2Sand Baths Are Essential
Like chinchillas, degus keep their coats clean by rolling in fine dust or sand. Provide a dust bath container with chinchilla-safe sand several times a week. Avoid water baths, as degus have difficulty drying properly and are prone to chilling.
3Extremely Sensitive to Sugar
Degus have a unique insulin response and are particularly prone to developing diabetes when fed sugary foods. Stick to a diet of high-quality pellets and timothy hay as staples, and avoid offering fruit or sweet treats as a general rule.
4They Need a Tall, Spacious Cage
Degus are energetic and enjoy climbing as well as running. Choose a metal cage with enough height and floor space to accommodate multiple platforms and a solid-surface exercise wheel. Wire mesh floors should be avoided to protect their feet.
5Monitor Dental Health Closely
Like all rodents, degus have continuously growing teeth, and providing ample timothy hay helps wear them down naturally. Malocclusion (misaligned teeth) can cause difficulty eating, so check their teeth regularly and consult an exotic animal vet if you notice any changes in eating habits.

6Never Grab Them by the Tail
Degus have a natural defense mechanism where the skin of their tail can detach if grabbed. This skin does not grow back, leaving a permanent injury. Always support their body when handling and never restrain or pull their tail under any circumstances.
7Temperature Control Is Critical
Degus are sensitive to heat and can suffer from heatstroke when temperatures exceed 28°C (82°F). Maintain their environment between 18–25°C year-round, using air conditioning in summer months. Good ventilation is also important, as high humidity can negatively affect their coat and respiratory health.
