What records should I start keeping from my kitten's first day?

Published October 29, 2026

The short answer

Start with identity and history on day one: her birth date if known, where she came from, any vaccinations and worming already done with their dates, her microchip number once she has one, and the food she is currently eating. Then keep a running log of weight, first vet visit findings, litter and appetite notes, and any illness or treatment, because patterns in those small entries are what a vet reads first when something goes wrong months later. In KinsLe, a Pet Passport keeps her vaccinations, weight notes, and visit records together in one portable packet, ready to hand over at any appointment.

The Identity and History Page

Begin her file with who she is and where she came from: her name, her birth date if the breeder or shelter knows it, a description of her markings, and the name and contact details of the breeder, shelter, or person who handed her over. Record the microchip number as soon as she is chipped, and keep the paperwork that came with her, even if it is only a handwritten note about her litter. This page sounds administrative, but it becomes precious fast: it is what identifies her if she is ever lost, what proves her history if you move or change vets, and what answers the questions every new clinic asks while you are trying to remember dates in a waiting room.

Health Records From the Very First Visit

Write down every vaccination and worming treatment she has already had, with the dates given to you at handover, then add each new one as it happens, along with flea prevention and any other treatment. At her first vet check, note her weight, the vet's findings, and anything you were told to watch, such as a mild heart sound to recheck or teeth to monitor as they change. If she is ever unwell, log the symptoms and when they started before you phone the clinic. Vets make better decisions from a timeline than from a worried summary, and the record you start now is the one that will show whether a problem is new or recurring.

The Everyday Log That Catches Problems Early

Beyond formal health records, keep simple daily notes for the first stretch: what food she eats and how much, how her litter tray looks, her weight at regular intervals, and milestones such as first using the tray reliably or starting solid food. Weight matters most. A young kitten should gain steadily, and a home log is often the first place a stall shows up, days before she looks any different. Appetite changes, a quiet day, or loose stools read very differently against a written baseline of normal days than they do from memory, especially when several family members share her care and each has seen only part of the picture.

The Small Details People Forget to Write Down

The entries owners regret missing are rarely the vaccinations, which come with paperwork anyway, but the small facts nobody issues a certificate for: the name and phone number of the breeder or shelter, the emergency and out-of-hours vet details, what her mother and littermates were like, the exact food brand and flavour she arrived eating, and the date she first used a tray or ate solid food. Photograph her markings too, including anything unusual like a kinked tail or an odd patch, because a written description plus a clear photo identifies a lost kitten far better than either alone. Add these now, while the answers are one phone call away.

Keeping the File usable for Years

A record only helps if it can be found and handed over, so keep everything in one place rather than scattered between a drawer, a phone photo album, and an email inbox. Bring it to every appointment, update it the same day while details are fresh, and pass a copy on if she is ever cared for by someone else or rehomed, so her history travels with her instead of being reconstructed from guesswork. That one-place habit is exactly what KinsLe's Pet Passport is built for: her identity details, vaccinations, weights, and visit notes held together in a single portable packet you can show at the vet, at boarding, or in any handover.
