A lifespan that surprises people
Degus live six to eight years in captivity, and individuals in excellent homes sometimes go further. That puts them in a different league from the hamsters and mice they are often shelved beside in people's minds, and much closer to the commitment of a rabbit or a small dog. Anyone choosing degus should plan housing, budget and daily care around the better part of a decade, and because degus are intensely social, that plan is almost always for a pair or a small group rather than a single animal. Two degus adopted as youngsters could still be climbing, digging and dust-bathing together when a child who begged for them has left primary school.
Diet is the biggest influence on those years
If one factor decides whether a degu reaches the top of its range, it is food. Degus evolved on sparse, fibrous grazing and their bodies handle sugar badly; sweet treats, fruit-heavy diets and sugary commercial mixes are linked with serious health trouble in this species, including problems with blood sugar regulation. The long-life degu diet is plain by design: unlimited hay as the backbone, a measured portion of a suitable plain degu food, leafy greens in sensible variety, and fresh water always available. It can look austere next to the colourful treat sticks sold for other rodents, but that plainness is precisely what keeps a degu's teeth worn, weight steady and digestion working year after year.
Space, company and things to destroy
Degus are busy, athletic animals, and a long life is also a well-occupied one. They need a tall, chew-proof metal enclosure with levels to climb, a solid running wheel, branches for gnawing and a dust bath offered regularly for their coats. Company of their own kind is not optional decoration: degus groom each other, sleep in piles and call back and forth, and a lone degu is a stressed degu. House them in same-sex pairs or groups formed carefully, and give the group enough hides and feeding points that lower-ranking animals eat and rest in peace. Chewing is a constant, so expect to replace wooden toys and shelves steadily across the years, and budget for that as part of the lifespan rather than a surprise.
Watching an animal across a long life
Over six to eight years you will see a degu change, and keeping simple notes helps you spot the shifts that matter. Weigh each degu now and then and jot the figure down, because gradual weight loss in a group animal can hide behind shared food bowls. Watch for a coat that turns dull or patchy, teeth that look uneven, slower climbing or a degu who stops joining the dust bath, and raise anything that persists with a vet who knows exotic pets. Senior degus often stay lively well into old age but may need softer lookout points, lower shelves and a little more warmth and quiet. The point at which to call the vet promptly is any degu who stops eating, becomes hunched and withdrawn, or shows rapid breathing, since small prey animals can go downhill fast.
Choosing degus with the decade in mind
Because the commitment is long, where your degus come from matters: healthy youngsters from a knowledgeable breeder or a rescue that can tell you their history give you the best start. Think ahead about holidays, house moves and changing work patterns across that span, just as you would for a dog. A degu's life generates years of vet visits, weight records and diet notes, and a KinsLe Pet Passport keeps that whole history in one portable packet, ready for a new vet, a boarding stay or a handover to a trusted keeper, so nothing about how your degus thrive gets lost along the way.
