Feeding and Weight Records
Start with what he eats and what he weighs. List the insects in his rotation, how many he typically takes at a feeding, how the insects are prepared and dusted in general terms, and how often he is fed for his age. Then set that beside a dated weight series. For a leopard gecko the tail is a visible store of fat, so note how his tail has looked over time — plump and steady, or visibly thinning — and let the numbers confirm what you have seen.
A tail that has slimmed while his appetite also fell is a pattern a new vet needs on paper, with the dates the change began. So is the opposite: an older gecko whose weight keeps climbing on the same routine may need his feeding reviewed, and the log is what makes that conversation concrete rather than guesswork.
Shed History and Skin Details
Record his sheds with dates and how completely they came away. Leopard geckos are known for shed sticking on toes, and repeated retained skin can constrict tiny toes over time, so note which toes have held shed, what you did about it — a shallow lukewarm soak and gentle help are the usual home steps — and whether it cleared. Note shed around the eyes as well, and any change in how he hunts or aims at insects afterwards, since difficulty catching food after a shed is worth the vet's attention.
Bring stool notes too: where he usually goes in the enclosure, how often, and any change in consistency or frequency, with dates. A gecko who stops producing stool, stops eating, or becomes lethargic should be seen promptly rather than waiting for a routine introductory appointment.
Temperatures and the Enclosure Picture
Write down the warm-side floor temperature where his heated hide sits, the cool-side temperature, and how the heat is provided and controlled by thermostat. Note his three hides — warm, cool, and humid — what substrate he is on, and whether anything in the setup changed recently. A photo of the enclosure spares a lot of describing and lets the vet spot a layout issue you might not think to mention.
Include any history of the humid hide being ignored, or of him spending all his time at one temperature end, since behaviour around the gradient often tracks with how well the gradient itself is working.
Background and Past Problems
Close the packet with his origin, approximate age, sex if known, and how long you have kept him. List past problems honestly: previous appetite losses and how they resolved, any parasites treated by a former vet, injuries, or a dropped and regrown tail — a regrown tail looks different from an original, and telling the vet saves a mistaken concern. If records from a previous clinic exist, arrange the transfer before the visit.
Add the questions you want covered: whether his weight suits his size, whether his supplement routine is balanced, and which changes should bring him back quickly. That short list turns a first appointment into a proper baseline.
Stored in KinsLe's Pet Passport, his feeding log, shed record, and temperature notes form one portable packet a new leopard gecko vet can read without chasing you for the missing pieces.
