Cat paperwork fails in a predictable way: the policy lives in an email, the vet's summary sits in a kitchen drawer, and the one invoice an insurer asks for is the one nobody can find. A simple filing system with fixed sections fixes this permanently, because every new document has exactly one obvious place to go. Set it up once, file each paper the day it arrives, and you will never reconstruct your cat's history from memory during a stressful claim again.
Section One: The Policy Itself
Keep the full policy wording, not just the certificate. File the schedule showing your cover level, annual limit, and the excess you pay per claim, the list of exclusions that apply to your cat, and the renewal notice each year. Highlight three things the day the policy starts: what is excluded, whether cover for an ongoing condition continues at renewal or resets, and the deadline for submitting a claim after treatment, which is easy to miss and can void an otherwise valid claim. If you switch insurer, keep the old policy documents permanently — questions about when a condition first appeared are answered from the old paperwork, and insurers do ask.
Section Two: Vet Records in Date Order
File every visit summary, invoice, and test result in the order the visits happened, newest at the front. Ask the clinic to email the clinical summary after each visit rather than relying on the receipt alone; the receipt says what you paid, while the summary says what was found, and claims are assessed on the summary. Include referral letters and specialist reports in the same sequence, and add a one-line note of your own for anything the paperwork misses, such as when you first noticed a limp or a change in appetite. That home note, dated when you write it, is often the detail that dates a condition correctly.
Section Three: A Claims Log
This is the section many owners skip, and the one that proves its worth at claim time. Keep a single running list — paper or digital — with one line per claim: the date filed, the condition, the clinic, the invoice total, the amount reimbursed, and the claim reference. The log tells you at a glance how much of your annual limit is used, whether a reimbursement is still outstanding, and which conditions are now on record as pre-existing for future claims. Chase any reimbursement that has not arrived within the insurer's stated timeframe using the reference from the log, rather than starting the conversation from scratch.
Sections Four and Five: Certificates and Identity
File vaccination records, any health certificates issued for travel or boarding, and routine treatment records together, and keep your cat's identity papers in their own section: microchip number and the registry it is recorded with, a note of the contact details registered to the chip, a clear recent photograph, and any registration or adoption papers. Check the chip's registered phone number once a year — a chip with an old number is only half an identity. Catteries, new vets, and insurers all ask for items from these two sections, usually at short notice.
Paper Originals, Digital Backup, Same Names
Keep the physical folder somewhere fixed and tell another household member where it lives. Scan or photograph every document into a digital folder that mirrors the five sections with the same names, and file the digital copy the same day the paper one arrives. Name files by section and topic so they sort and search sensibly. When you travel or board the cat, a printed mini-pack — policy summary, latest vet summary, vaccination record, microchip number, and your emergency contact — covers almost every situation without handing over the whole folder.
Do a short annual review at renewal: confirm the log matches the year's claims, check exclusions have not quietly changed, shred superseded schedules, and confirm the chip details and emergency contacts are current. KinsLe Pet Passport supports exactly that tidy-up by holding your cat's records together in one portable packet you can present at the vet, the cattery, or alongside an insurance claim.
