What records does a pet insurer usually ask for when I make my first claim for my cat?

Published October 26, 2026

The short answer

For a first claim, an insurer usually asks for your cat's complete clinical history from your vet, not just the invoice for this illness, because a first claim is when they check for anything pre-existing. Expect itemised invoices and proof of payment for the treatment claimed, identification details including the microchip number, and vaccination and weight records where the policy asks for them. The common delay is a gap, such as a previous practice's history you never transferred or notes that stop before you adopted your cat, so ask your vet to send the full history directly and keep your own copy. KinsLe's Pet Passport gathers your cat's records into one portable packet, so that first-claim history is complete before anyone asks.

Why a First Claim Asks for More Than Later Ones

A first claim is the point at which an insurer builds your cat's file, so the request is wider than the single illness or injury you are claiming for. Alongside the claim form, expect to be asked for the complete clinical history your vet holds — every consultation, test, and treatment note, not just the recent episode. Insurers use that history to confirm your cat's age, breed, and identity, and to check whether the condition, or signs of it, existed before the policy started. Owners are often surprised by the breadth of the request and lose days gathering it, which is why assembling the file before you need it changes a first claim from a scramble into a formality.

The Core Documents, One by One

The invoice set matters in detail: insurers want itemised invoices showing each charge separately, plus proof you paid, such as a receipt or card statement line. Your cat's identification details come next — microchip number, breed, age, and the name the vet record is held under, which must match the policy or you will be asked to explain the difference. Many policies also ask for vaccination status and, for some conditions, a weight history, both of which live in the clinical record. If your cat was treated at two practices for the same episode, for example your own vet and an out-of-hours clinic, both sets of notes and invoices belong in the claim.

The Gaps That Delay First Claims Most

The classic delay is a history split across practices. If you changed vets, adopted your cat as an adult, or used an emergency clinic once, the insurer may receive a history with a silent hole in it and pause the claim until it is filled. Close those gaps now: ask any previous practice to forward its records to your current vet, and keep your own copies of adoption medical notes so the story before your ownership is documented as far as it can be. A second delay is mismatch — a cat insured under a slightly different name or age than the vet holds — which a quick comparison of the two files catches in minutes at home instead of weeks inside a claim.

Your Vet's Part and How to Make It Easy

Most insurers are happy for your vet to send the clinical history directly, and many claim forms include a section the practice completes. Make that easy by telling the clinic exactly which claim it relates to, confirming the email or portal the insurer wants used, and asking the practice to tell you when it has been sent. Keep copies of everything you submit, with the date, in your own claim folder. If the insurer asks a follow-up question, answer it with documents rather than recollection wherever you can — a dated note from the history settles questions that a phone call leaves open.

Assemble the File Before Anyone Is Ill

The best time to build a claim-ready file is a healthy week, not the night your cat comes home from surgery. Collect the full clinical history, identification details, vaccination record, and your invoices into one place, and update it after each visit. KinsLe's Pet Passport keeps your cat's records together in one portable packet, ready for vet visits and handoffs, which means that when a first claim arrives, the complete history an insurer asks for is already assembled rather than chased practice by practice.
