A degu health check fits naturally into the middle of the day, because degus are daytime animals and a check done when yours is awake tells you far more than one done on a sleepy animal dragged from a nest. Keep it weekly, keep it brief, and let observation do most of the work: a healthy degu is busy, vocal, social, and almost constantly in motion between climbing, running, and grooming, so a change in that energy is itself a finding. Brief, gentle handling covers the rest, with one degu-specific rule that shapes the whole check: never lift or catch a degu by its tail.
Behaviour, appetite, and droppings first
Watch the group or the individual for a few minutes before you open the enclosure. A well degu moves confidently, uses its wheel and shelves, greets cage mates, and comes to investigate food. Note any degu sitting apart, hunched and puffed up, being excluded at feeding time, or moving with a limp, a wobble, or reluctance to climb. Then read the enclosure. Droppings should be plentiful, dry, and firm; a sharp fall in quantity, or droppings turning small or soft, is an early gut warning. Check that hay and food are actually being eaten rather than scattered, and that the water bottle is working and going down at its usual rate. Because degus handle sugar poorly, the check is also a moment to confirm the diet on offer is built on hay and suitable plain food, without sweet treats creeping in as a habit.
Eyes, nose, teeth, and coat up close
Settle the degu in your lap or cupped hands on a low surface. Eyes should be bright and clear, without discharge, cloudiness, or white patches developing in the lens, which are worth reporting to a vet if you notice them appearing. The nose should be dry, breathing quiet, with no sneezing fits or clicking. Lift the lip gently to see the front teeth: they should be a healthy orange colour, meet evenly, and show no overgrowth, slanting, chips, or breaks. Drooling, wetness under the chin, dropping food, or favouring soft food over hay all suggest the teeth you cannot see, at the back, need a vet's examination.
The coat should be smooth and complete. Look for bald patches, thinning, scabs, or relentless scratching at one area, and run a hand lightly over the body to feel for lumps or spots where the degu flinches. Check feet and nails for redness, swelling, or nails catching and curling, especially in older degus that climb less.
The tail rule and finishing the check
A degu's tail is a genuine weak point: if the tail is grabbed, the skin can slip off the end as an escape response, leaving an injury that needs veterinary care. So during checks, scoop the degu from underneath, let it walk into a tube or your cupped hands, and let the tail alone entirely. While you are there, look at the tail itself for wounds, swelling, or a damaged tip, since cage mates and caught wheels can injure tails without any handling at all. A quick weekly weigh-in, written down, completes the picture, because gradual weight loss in a degu that still appears busy is easy to miss by eye.
Book a vet promptly for a degu that stops eating, drools, breathes noisily, develops eye cloudiness, has a tail injury, or goes hunched and quiet away from the group. Bring the timeline with you.
That timeline is far more useful written than remembered, and KinsLe Pet Passport keeps a degu's dated check notes, weights, and past vet findings together in one packet ready for any visit.
