Many people assume degus live only 1-2 years like hamsters, but in captivity with proper care they can reach 6-8 years. This is closer to the lifespan of a guinea pig than a small rodent.

Our editorial team has gathered the most accurate information on degu longevity in captivity. A degu’s lifespan depends heavily on diet, housing, and genetics, not just luck.

Average and Maximum Lifespan

In captivity, degus typically live 6 to 8 years, though some individuals reach 10 years with optimal care. Wild degus rarely exceed 2-3 years due to predation and food scarcity.

Factors like gender, neutering, and genetics influence longevity. Females may live slightly longer than males, and neutered degus avoid reproductive cancers.

Diet and Its Impact on Longevity

Degus are prone to diabetes and obesity, so a low-sugar, high-fiber diet is critical. Their staple should be grass hay (like timothy or orchard grass) and a small amount of low-carb pellets formulated for chinchillas or degus.

  • Never feed fruits, sugary vegetables, or treats with molasses.
  • Provide fresh water daily and avoid vitamin C supplements (degus synthesize their own).

Housing Requirements for a Long Life

Degus need large, multi-level cages with solid floors (wire floors hurt feet). Minimum size for a pair is 30x18x36 inches, but bigger is better. They require deep bedding for digging and multiple hiding spots.

Temperature should stay between 60-75°F (15-24°C). Above 80°F can cause heatstroke. Place the cage away from drafts and direct sunlight.

Common Health Problems and Prevention

Dental issues are common because degu teeth grow continuously. Provide wooden chews and pumice stones to wear down teeth. Signs of overgrowth include drooling, weight loss, and reduced appetite.

Diabetes is another risk. Watch for excessive drinking, urination, and lethargy. Annual vet checkups with a rodent-savvy veterinarian can catch problems early.

Social Needs and Enrichment

Degus are highly social and should live in same-sex pairs or groups. A solitary degu can become depressed and live a shorter life. Provide daily out-of-cage time in a secure playpen.

Enrichment includes wheels (solid surface, no wire), tunnels, and puzzle feeders. Rotate toys to prevent boredom. Interaction with their human family also boosts wellbeing.
