What normal brumation looks like
Brumation is the reptile version of a winter slowdown, and its defining feature is how ordinary the dragon remains inside it. It usually begins as the days shorten: appetite tapers over a few weeks rather than stopping overnight, basking sessions shrink, and he retreats to the cool side or his hide to sleep for most of the day. Crucially, a brumating dragon roused for a check is alert — eyes open and bright, head up, body responsive — and between sleeps he may emerge to bask or take a small meal before retreating again. His weight stays essentially stable across the whole period, because a healthy dragon enters brumation with reserves and spends them very slowly. The onset is also gradual: a dragon who was thriving last month and is sleepy this month fits the pattern.
The illness signs that break the pattern
Illness announces itself with signs brumation never produces. A persistently black beard — especially paired with a tucked, tense posture — signals pain or distress, not sleepiness. Sunken, dull, or crusty eyes, discharge from the nose or mouth, wheezing, clicking, or open-mouth breathing all point to problems no season explains. So do runny or foul stools, visible weight loss with the hip bones and tail base thinning, limbs that tremble or will not bear weight, and a dragon too weak to lift his head or right himself. Timing matters too: a dragon who crashes suddenly, or becomes lethargic in the middle of the active season, or who was already a picky eater with loose stools before slowing down, should never be waved through as 'probably brumating'.
The grey area — and how weight settles it
The genuinely hard cases are the slow ones: a dragon who sleeps a great deal and eats little, with no dramatic symptom to point at. This is where a scale earns its keep. Weigh him before the quiet season and at intervals through it; a brumating dragon's line stays nearly flat, while a sick dragon's declines steadily even when he looks unchanged. Keep his lights and temperatures correct and unchanged — dropping them to 'help' him brumate can mask a husbandry problem or deepen an illness. Offer water and occasional food on his waking days and note what he takes. A downward weight trend over several checks, or any single red-flag sign appearing, ends the watch-and-wait period.
The pre-brumation vet check removes the guesswork
Because the two states overlap so much, many keepers remove the ambiguity entirely: a vet visit with a faecal test before the brumation season confirms he is parasite-free, well-fleshed, and genuinely fit to sleep. Parasites are the classic trap — a dragon carrying a burden slows down exactly like a brumating one, then declines through the winter when he should be coasting. If your dragon slows unexpectedly outside that checked pattern, treat the vet visit as the first step rather than the last resort. Bring the evidence with you: his weights across recent weeks, appetite notes, stool changes, and temperatures. That history is what the KinsLe Pet Passport exists to keep together — his records in one packet, ready for the vet visit, so the decision between brumation and illness rests on his documented pattern rather than your recollection of it.
