Degu vs Chinchilla: Which Should You Get?
🤎 The short version: degus and chinchillas are close cousins in care — both social, cool-climate, hay-first grazers with ever-growing teeth — but they suit different people. A degu is the diurnal, interactive, daytime rodent with one iron rule: no sugar, ever. A chinchilla is the soft, nocturnal, 15–20-year companion that must be kept cool and bathes in dust. Both are intermediate pets, not starter pets.
At a glance
| Degu | Chinchilla | |
|---|---|---|
| Active | Diurnal (daytime) | Nocturnal |
| Lifespan | 6–8 years | 10–15 (up to 20) |
| Iron rule | No sugar (diabetes-prone) | Keep cool; dust-bathe only |
| Cage | Tall, metal (they chew out) | Tall, multi-level |
| Company | Colony — never alone | Social — never alone |
| Handling | Tames with patience | Not cuddly; handle gently |
What they share
Quite a lot. Both are social and must live with their own kind, both need a large, tall, multi-level cage, both are hay-first grazers whose continuously-growing teeth depend on unlimited hay, both dust-bathe rather than water-bathe, both dislike being lifted by the tail (each can shed skin/fur if grabbed), and both are cool-preferring rodents that hide illness. If you’re drawn to one, you’ll recognise the other.
The deciding differences
Activity. This is the big one for many people. Degus are diurnal — genuinely awake and busy when you are, sunbathing and chattering — which almost no other rodent offers. Chinchillas are nocturnal, bouncing around after dark.
Lifespan. Chinchillas are a much longer commitment (10–15, up to 20 years) than degus (6–8). If you want a very long-lived pet, the chinchilla; if a shorter (but still multi-year) one, the degu.
The non-negotiable rule differs. For degus it’s sugar: they’re highly prone to diabetes and cataracts, so no fruit, no sugary treats, nothing with molasses — ever. For chinchillas it’s heat: their dense fur means they overheat easily and need 10–18°C, with fatal heatstroke a real risk in warm rooms. (Degus must be kept cool too — no warmer than ~20°C — but the headline chinchilla risk is heat, and the headline degu risk is sugar.)
Cage material. Degus chew through plastic and wood, so their cage must be metal; chinchillas need a tall multi-level cage with solid resting areas over any wire.
Who should get which?
- Get degus if you want a daytime-active, interactive rodent and can commit to an absolutely strict sugar-free diet for life.
- Get chinchillas if you want a soft, long-lived (15–20 year) companion, can keep a room reliably cool, and are happy with a nocturnal, hands-off-ish pet.
The honest takeaway
Same family, different lives: degus for daytime interaction with a sugar rule you can never break; chinchillas for a decades-long, cool-and-dusty commitment. Read the full degu and chinchilla care guides to see which fits your home.

Common questions
Are degus or chinchillas better pets?
It depends what you want. Degus are diurnal (awake in the daytime), interactive and long-lived at 6–8 years, but need a strict no-sugar diet. Chinchillas are nocturnal, softer and even longer-lived (10–20 years), and need to be kept cool and dust-bathed. Both are social and must be kept with their own kind.
Do degus and chinchillas have similar care?
They share a lot: both are social, cool-climate, hay-first grazers with continuously growing teeth that need a companion, a tall cage and gnawing material. The big differences are activity (degu diurnal, chinchilla nocturnal), lifespan, the degu’s strict no-sugar rule, and the chinchilla’s dust-bath and heat sensitivity.
Can degus and chinchillas live together?
No — keep each species with its own kind. Degus need degu company and chinchillas need chinchilla company; they have different sizes, temperaments and needs and shouldn’t be housed together.
Which is easier for a beginner, a degu or a chinchilla?
Both are intermediate-level pets, not starter pets. Degus demand an unbreakable no-sugar diet; chinchillas demand cool temperatures and a 15–20 year commitment. Neither is low-effort, so choose based on which set of needs fits your home and schedule.
