A degu's teeth never stop growing, and what a young degu eats in its first months sets the pattern those teeth — and the body behind them — will follow for years. Degus evolved on dry, fibrous mountain scrub with almost no sugar in it, and their systems handle sweet food badly. The dental side of the same story is mechanical: teeth worn down by long hours of chewing hay stay level and aligned, while a soft, sweet diet lets them overgrow and misalign. Day one is when both habits form, so the rules below are worth treating as permanent rather than as a starter phase.
Rule one: hay does the dental work
Keep grass hay in front of your young degu at all times, in a rack, a pile, and stuffed into cardboard tubes so eating it fills the day. The side-to-side grinding of long hay strands is the motion that wears a degu's molars evenly, and no pellet or chew toy fully substitutes for hours of it. Vary hays if your degu is picky — different grass hays have different textures — but never let the supply run to dust at the bottom of the bag and call it available. A degu that stops eating hay while still taking treats is an early dental warning, not a preference to indulge.
Rule two: read labels like sugar is hiding, because it is
The young degu's pellet should be plain, and its ingredient list is where that is decided. Refuse mixes bound with molasses, honey, cane sugar, syrups, or fruit concentrates, and be suspicious of colourful blends with visible sweet pieces — a degu will mine those out first and leave the nutrition. The same check applies to anything marketed as a treat: honey sticks, yogurt-style drops, and dried fruit pieces are sugar in costume, and degus do not need them to feel rewarded. A piece of plain dried herb, a broccoli floret, or a fresh hay strand from your hand does the bonding job without the metabolic cost. Even naturally sweet vegetables such as carrot and sweet potato belong in rare, thumbnail-sized amounts rather than the daily rotation.
Rule three: chewing variety, not sugary variety
Interest in a degu diet comes from texture and work, not sweetness. Offer safe untreated wood to gnaw, hay twisted into bundles, a cardboard roll stuffed with hay and a herb leaf, and the occasional plain dried dandelion or plantain leaf. Rotate these across the week so the enclosure asks new questions of the teeth and the brain. Keep fresh water available constantly and watch that drinking stays normal — a sudden change in thirst in a degu is worth mentioning to a veterinarian, given the species' sensitivity around sugar handling.
The dental watch, and when to act
Check weekly that your young degu is eating hay eagerly, keeping weight, and producing plentiful dry droppings. See a veterinarian promptly for drooling or a wet chin, food dropped or chewed on one side, reduced hay intake, weight loss, overgrown or uneven front teeth, or a degu pawing at its mouth — molar problems in degus happen out of sight at the back of the mouth, so behaviour changes are often the first evidence you get. Ask the vet to check the back teeth at every routine visit even when everything looks fine, and keep a note of what was found. Those notes build into a real dental history when KinsLe Pet Passport holds your degu's diet records and examination findings together in one packet you can hand to any vet who treats it.
