A blue-tongued skink's most important day-one record is his subspecies, written down exactly as the breeder or seller stated it. Northern and Indonesian skinks live under noticeably different humidity expectations, and a care log that never names which one you own cannot tell you whether your readings are right. Alongside the subspecies, record where he came from, what he was fed before, his approximate age if known, and clear photos of his back, belly, and toes on arrival day.
Humidity and temperature readings belong in the log
Write down basking and cool-end temperatures plus humidity readings for your blue-tongued skink's enclosure, taken at skink level rather than at the lid. Humidity that swings wildly between morning and evening is worth recording as a range, because a skink shedding poorly in dry air tells a different story from one shedding poorly in correct air. Note what you changed when readings drifted: a deeper water bowl, a humid hide, a substrate swap. Readings taken before misting and again in the evening tell you more than either number alone, because the gap between them shows how quickly the enclosure dries out. Months later, that cause-and-effect trail is what separates a setup that was fixed from one that was merely endured.
What your skink ate, meal by meal
Record each meal's rough makeup for your blue-tongued skink: the protein offered, the vegetables and greens mixed in, and whether the bowl came back empty or picked through. Skinks are enthusiastic eaters prone to gaining weight quietly, and a feeding log is the only honest check on how often rich meals actually happened. Note supplement dusting days too, and any food refused outright, since a skink who suddenly ignores a longtime favourite is showing you something. Weigh him on a regular rhythm and write the number next to the week's meals so trends are visible at a glance.
Sheds, toes, and skin notes
Log every shed your blue-tongued skink completes, and inspect the toes each time, writing down whether the old skin cleared fully. Retained shed around a skink's small toes can tighten unnoticed, and a written note that the last two sheds left residue is exactly the pattern worth acting on. Add observations about scale condition, any sneezing or bubbling at the nostrils, and the state of his stools. Note brumation behaviour in cooler months as well: which weeks he hid away and skipped meals, so a normal seasonal slowdown is not mistaken for illness next time it comes around.
Vet entries and the threshold for using them
Keep each vet visit recorded with its reason and outcome, and keep the arrival paperwork with it. Contact a reptile vet if your skink's toes keep shed skin across consecutive sheds, if breathing sounds wet or strained, if weight climbs or falls steadily across several weigh-ins, or if a normally bold feeder refuses food well outside a brumation pattern. Arriving with the subspecies, the humidity history, and the meal log gives that vet the context skink cases depend on. Storing the subspecies note, humidity trail, feeding log, and vet entries together in a KinsLe Pet Passport means a blue-tongued skink's records stay matched to the care his particular kind actually needs.
