Identity and origin paperwork
Start with what proves which animal this is. The new keeper should receive the species identification — scientific name as well as common name — the morph or colour form, sex if known, and hatch or birth date if recorded, or an honest estimate clearly labelled as one. Add where the animal came from: the breeder or previous keeper, when you acquired it, and any purchase paperwork. If you hold identification photographs, include the set, so the new keeper can confirm at a glance that the paperwork and the animal match. Morph identity matters practically, not just commercially: some forms carry known sensitivities, and a keeper who knows exactly what they have can look up the right care from day one.
The care history the new keeper needs
The feeding record is the most valuable document in the folder. It shows what prey or foods the animal takes, the sizes, the interval, and its individual quirks — the gecko that only strikes at night, the snake that refuses during shed, the tortoise that ignores all but one kind of leaf. Add shedding history, the temperatures and humidity the animal is actually kept at, its light cycle, and the enclosure setup it is used to. A keeper who replicates the old conditions for the first weeks gives the animal continuity while it settles; a keeper handed nothing has to guess, and reptiles pay for guesses with refused meals and stress.
Health and veterinary records
Pass on every vet record you hold: visit dates, what was examined, any findings and follow-ups, and treatments the animal has had, including parasite treatments and their dates. Note health history that never reached a vet as well — past retained sheds, a regurgitation pattern that resolved, an old injury fully healed — with dates and outcomes as you observed them. Disclose honestly: a known history protects the animal, because the new keeper watches for the right things, and it protects you, because a problem declared at handover cannot later be called a hidden one. If the animal was ever quarantined away from a collection, the dates and the reason belong in the file too.
Legal documents that travel with listed species
Some reptiles carry paperwork that is not optional. Tortoises of listed species travel with their certificates, and those documents must transfer with the animal — a tortoise separated from its certificate creates legal and resale problems for everyone who owns it afterwards. The same applies to any species held under permit or licence: include copies of the permit, and note what the new keeper must register in their own name and area. Check microchip registration too, where one is fitted, so the chip can be transferred rather than pointing at you forever. Never let the animal move first with the documents promised to follow later; later has a way of not arriving.
Signing the handover over properly
Finish with a simple written transfer note: the date, both names, the animal's description, and a line confirming the documents listed were received — signed by both sides, each keeping a copy. Then hand over the whole bundle at once: identity, care history, health records and legal papers, ideally with a photograph of the animal taken on the day. The animal starts its new home with its past intact instead of blank. KinsLe's Transferrable Profiles complete that handover digitally, moving the pet's profile, records and routines to the new owner in one piece.
