Proof of identity and how the animal came to you
The foundation of the file is evidence of what your reptile is and that it is legitimately yours. Keep the receipt or written note from whoever supplied it — shop, breeder, rescue, or a friend rehoming it — stating the species, the date, and the seller's details. Beside it, record the animal's sex if known, its age or hatch date, and where it originally came from. Take clear photographs of its pattern and any distinguishing marks at the same time. This bundle answers the first questions anyone asks — an insurer, a vet registering it, or a rescue if you ever need to rehome it — and it proves the animal was legally obtained, which matters most for species that are commonly wild-caught or smuggled.
Legal documents its species requires
Some reptiles carry legal paperwork and some do not, and the keeper's job is knowing which. A listed tortoise species needs its Article 10 certificate kept safe for any future sale. Certain species need import documents, local permits, or licences depending on where you live, and animals bought from abroad may have export and import papers that should travel with them for life. If your reptile arrived with any official-looking certificate, keep the original somewhere dry and safe, scan a copy, and never let the original leave with anyone except a genuine future buyer or keeper.
The living records that build up over time
This is the part of the file that grows: vet visit notes and invoices, weights taken at intervals, feeding records, shed dates for snakes and lizards, and notes of any illness, treatment, or change in behaviour. Add microchip details if your animal is chipped — the number, where the chip sits, and confirmation the registration carries your current contact details. Also jot down enclosure facts that you will otherwise forget: when the UV bulb was last replaced, what size the enclosure is, and which thermostat and heater models you use. Six months on, nobody remembers the bulb date, and it genuinely affects the animal's health.
How to store it so it survives
Paper in a drawer fades, gets damp, and disappears in a house move. Keep the originals of legal documents in one clearly marked folder, scans or photographs of everything in a second place, and the day-to-day logs wherever you will actually write in them. If you keep several reptiles, one file per animal prevents the classic muddle of a vet note with no name on it. Review each file once in a while — when you do a deep clean is a natural moment — and add the new weights and receipts before they scatter.
One more item earns its place in the file: a short who's-who of help. Write down your usual vet's name and number, the exotics practice you would use in an emergency, and the person who feeds your animals when you travel. Paperwork is not only about the reptile — when something goes wrong at short notice, the file should tell whoever steps in exactly where the animal is registered and who already knows it.
Holding all of this in KinsLe's Pet Passport turns the folder, the scans, and the scribbled logs into one tidy packet per reptile that can be handed to a vet, sitter, or new keeper complete.
