A crested gecko's boarding paperwork should be short, specific, and written for the two moments it will actually be used: the quiet evening check, and the rare urgent one. Because he is small, nocturnal, and easily stressed by heat and handling, the packet travelling with him needs to stop a boarder over-reacting to normal gecko behaviour while making genuinely abnormal signs impossible to miss or delay over.
Put decision-makers ahead of general contacts
Lead the first page with your mobile number and your realistic availability, then a named backup who has agreed to authorise veterinary care and could collect him if the stay had to end early. Crested gecko problems that matter often surface in the evening, when he is active, so a backup who only answers in office hours is a weak link; choose someone who can take a night-time call. Make the call order explicit — boarder to you, then to the backup, then straight to the vet for the red-flag signs you list — so nobody wastes the evening exchanging messages while a small animal waits.
List a reptile vet who will see a tiny gecko
Write your reptile vet's practice name, address, and number, and whether your gecko is registered there, then add an out-of-hours service as a fallback, since not every emergency clinic is equipped or willing to treat a very small lizard. A brief note of his approximate weight and length helps a vet who has never seen him judge whether a description over the phone sounds proportionate. Beside the numbers, set your thresholds in advance: being found limp or unresponsive, signs of overheating after a hot room, a prolapse, or a visible injury from a fall means seek care immediately, while one untouched food pot does not.
Use the snapshot to prevent false alarms
Your one-page health note should name the powdered diet he accepts and how it is mixed, his feeding nights, his last known weight if you track it, and his ordinary pattern of sleeping curled in foliage by day and exploring after dark. Include the two sights most likely to alarm an unfamiliar boarder: colour change between pale fired-down and dark fired-up states, and a dropped tail. Explain that tail loss, while permanent, is a known stress response and not a bleeding emergency, but that the circumstances matter — a drop after a fall or rough handling should still be reported to you the same evening. Accurate normals are what make the abnormal recognisable.
Sign the permission and settle the money question
Attach a brief signed authorisation for the boarder to obtain emergency care on your behalf, with a clear line on payment — card by phone from you, the practice holding your details, or your backup authorised to pay. For a low-cost animal, this paragraph matters more, not less: it removes any hesitation about whether treatment will be covered and confirms in writing that his care is to be pursued properly. If he has had any recent vet attention, include that paperwork copy; otherwise a clean snapshot is sufficient and a thick folder of irrelevant history only hides the pages that count.
Make the front sheet the nightly one
Clip his practical summary where the boarder will see it each evening: mist lightly at night, keep the room in the low to mid 70s Fahrenheit and act if it climbs toward the mid 80s, offer food on the listed nights, and disturb him as little as possible by day. Repeat the vet and backup numbers at the bottom of that sheet rather than trusting anyone to dig through a folder at midnight. Photograph the whole packet before drop-off. KinsLe's Pet Passport gathers his diet notes, vet details, and signed permission into one portable packet that stays with him throughout the stay.
