Kitten insurance in the UK: when to insure and what to check

When can you insure a kitten?

The PDSA's guide to pet insurance says insurers generally accept pets from 8 weeks old. It also says most policies do not cover a pre-existing condition, so it is "important to take out pet insurance as soon as possible". A kitten with no vet history has the fewest exclusions.

New policies also have a waiting period. Which? says many policies treat anything that appears in the first 10 to 14 days after you sign up as pre-existing. Our new kitten checklist covers the other first-week jobs.

How much is kitten insurance?

No organisation publishes an average premium for kittens, so we do not quote one. The PDSA says premiums are calculated on your pet's age, breed, your postcode area, any claims history, and may be more expensive for a pedigree. The cover type and excess you choose matter too: lifetime cover usually costs more than time-limited cover, and a higher excess usually lowers the premium.

Free cover from a rescue or breeder

Cats Protection says adopting a cat from it includes four weeks' free pet insurance, alongside neutering, microchipping, vaccinations and a health check (Cats Protection, checked 21 October 2026). Some breeders also hand over a kitten with a short free policy.

• Note the end date. Free cover stops on its own; arrange a policy before then if you want continuous cover.
• Ask what happens if you continue it. Continuing with the same insurer may keep conditions diagnosed during the free weeks covered; a new insurer would treat them as pre-existing.
• Check the limit and type. Compare the free policy's vet-fee limit and cover type with what you would choose.

Does an indoor kitten need insurance?

Indoor kittens avoid some outdoor risks, but not all vet bills. The PDSA's indoor cats advice says indoor cats can put on weight or get stressed because they cannot go out to explore, and notes outdoor risks such as road traffic accidents and FIV, which passes between cats through bites (PDSA, checked 21 October 2026). Illness, dental disease and long-term conditions can affect a cat wherever it lives.

Some insurers ask whether your cat goes outdoors. Answer accurately: if a cat that was indoors starts going out, tell the insurer. Our cat insurance guide sets out the costs of common cat conditions.

Do vaccinations affect kitten insurance?

Insurance does not pay for vaccinations, but they can affect claims. The PDSA warns that "if your pet falls ill with an illness that was preventable through vaccination the cost of your pet's treatment may not be covered". Some policy wordings ask you to keep vaccinations up to date as your vet recommends, so ask your vet which vaccines your kitten needs, including if it will live indoors.

Cats Protection estimates annual vaccinations, including the initial ones a cat needs, at about £70 to £90. Our cat vaccination cost guidehas practice prices. If you are worried about your kitten's health, contact your vet.

What does kitten insurance cover?

Kitten insurance is ordinary pet insurance for a young cat: it pays vet fees for accidents and illness up to the policy limit. The PDSA lists routine care that insurance may not cover: vaccinations, spaying and castration, flea, worm and tick treatments, grooming and claw clipping, teeth maintenance. A practice health plan spreads those routine costs instead; see pet health plans vs insurance.

On the 2024 average claim, the insurer in this example pays £586. Try your own figures in the claim calculator.

What changes as your cat gets older?

The policy you pick for a kitten may still be running when your cat is a senior, so read the age rules now. Defaqto found that 72% of cat policies add a compulsory co-payment from a set age, most often at 10 (27% of cat policies), and most charge 20% (Defaqto, June 2024 data). How that adds up is in our excess guide, and the difference between cover types is in lifetime vs annual pet insurance.
