Identity papers: who this animal actually is
The first documents name the animal properly. You should receive the species' common name and its scientific name, because care differs sharply between lookalike species and a vague label like "python" is not an identification. Alongside that: the hatch date, so you know the baby's true age; the sex, and how it was determined, since incubation temperature alone is not a guarantee in many species; and the morph and genetic background, including any possible recessive traits the baby may carry, which matters for its value and for anyone who might breed from it later. The parents' identities belong in the same envelope — a breeder who cannot say who produced the clutch is telling you something.
The feeding record
This is the single most useful sheet in the packet. It should show what the baby has been eating — prey type and size, and for snakes whether it takes live or frozen-thawed food — how often it has been fed, and the dates of its last several successful feeds. A baby that has eaten steadily for its breeder, on food you can actually obtain, is a baby that starts well with you. Notes about refusals matter too, including what tempted it back: the trick that worked for the breeder is the first trick you will need if the move unsettles it.
Health and growth history
Ask for the baby's weight, and ideally its length, on the day of sale — this is the baseline every future gain or worrying loss is measured against. Shed dates, and whether sheds have come away complete, belong here as well. If the animal has been examined by a vet, had a parasite screening, or received any treatment, the notes should come with it, honestly written. A short note about a slow start or a missed feed, recorded plainly, is worth far more than a packet scrubbed clean of anything but good news.
The breeder's side of the bargain
The packet should identify the seller completely: full name, address and a working phone number or email, the date of sale, and a receipt for the price paid. Any guarantee the breeder offered — on feeding, on health in the first days, on the stated sex — should be in writing, not remembered from a conversation, together with what the breeder asks you to do if the baby fails to thrive after the move. Serious breeders expect these questions and answer them in the paperwork as a matter of pride.
Permits and special paperwork
Some species travel with legal documents, and these are not optional extras. Tortoises and other listed species may need CITES paperwork or an Article 10 certificate; imported animals should come with their import documentation; a microchipped animal should arrive with its chip number and registration details; and a few species need local licences or sale records depending on where you live. If a species legally requires a certificate and the seller has none to show you, that is a stop sign, not a detail to sort out later.
Red flags in an empty envelope
A breeder who provides nothing at all — no hatch date, no feeding history, no parentage, no receipt — is asking you to take the animal's whole past on trust, and the reptile hobby's problem sellers rely on exactly that. Walk away from vague dates and unrecorded feeds, because you will be the one explaining the gaps to a vet. From day one, file the whole packet in KinsLe's Pet Passport, and your baby reptile's breeder documents, weights and vet notes travel with it to every appointment and any future home.
