Cat Vaccinations UK: Schedule, Boosters and Costs

Vaccination is the cheapest, simplest thing you can do to keep a cat alive and out of serious trouble. The diseases it prevents are common, miserable and often fatal, and several of them have no cure once a cat is infected. Here's exactly what UK cats need, when they need it, what it costs, and the questions worth asking your vet.

Which vaccinations do cats need in the UK?

UK vaccines fall into two groups: core jabs that every cat should have, and non-core jabs given based on lifestyle and risk. All the major UK authorities — the PDSA, RSPCA and Cats Protection — agree on the same short list.

Core vaccines (every cat, including indoor cats)

• Cat flu — protects against feline herpesvirus (FHV) and feline calicivirus (FCV). Cat flu causes sneezing, runny eyes and nose, mouth ulcers and fever. It can be fatal in kittens and in older cats with other illnesses, and cats that recover often become lifelong carriers that flare up under stress.
• Feline infectious enteritis — also called feline panleukopenia or feline parvovirus. A severe, frequently fatal gut infection. The virus is extremely hardy and can survive in the environment for a long time, which is why even indoor-only cats are at risk.

Non-core vaccine (lifestyle-based)

• Feline leukaemia virus (FeLV) — a virus that attacks the immune system and can cause fatal cancers and anaemia. Cats Protection notes that most cats die within three years of an FeLV diagnosis. It spreads through direct contact between cats — saliva, bites and grooming — not through the air. It's recommended for any cat that goes outdoors or mixes with other cats. A strictly indoor cat with no feline contact may not need it, but discuss this with your vet.

Rabies (only for travel)

Rabies vaccination isn't part of the routine UK schedule because the UK is rabies-free. It's a legal requirement if your cat is travelling in and out of the country under the pet travel rules. If you're planning to take your cat abroad, speak to your vet well in advance, as there are timing rules to follow.

The UK cat vaccination schedule

Kittens

Kittens are protected by their mother's antibodies for the first weeks of life, which is why the primary course is given as two injections rather than one — the second dose takes over as maternal immunity fades.

| Stage | Timing | What happens | | --- | --- | --- | | First injection | From 8-9 weeks old | Primary dose of core vaccines (plus FeLV if needed) | | Second injection | 3-4 weeks after the first (around 12 weeks) | Completes the primary course | | Occasionally a third | Around 15-16 weeks | Some vets add a dose where high maternal antibodies are likely | | Full protection | 3-4 weeks after the final injection | Keep the kitten indoors until then |

Guidance varies slightly between organisations — the RSPCA cites a first set at nine weeks and a second at 12 weeks; Cats Protection says kittens can start from around eight weeks. Both describe the same two-dose course three to four weeks apart. Your vet will set the exact dates.

Keep your kitten indoors until the course is finished and they've had time to develop immunity. Letting them outside too early is one of the most common and avoidable mistakes.

Adult cats

After the kitten course, cats need a first booster one year later to lock in immunity, then regular boosters for life.

Boosters are not all given at the same interval. As a general guide the PDSA notes protection lasts around three years for herpes, calicivirus and panleukopenia, but only about one year for FeLV. In practice this means your vet may give the FeLV and cat-flu components yearly while spacing the enteritis component every three years — but your cat still has an appointment every year for the components that need it, plus a full health check. Don't skip the annual visit just because "the big jab" isn't due; the yearly exam catches problems early and keeps the vaccination record valid.

If your cat's boosters lapse for too long, your vet may need to restart the primary course with two injections rather than a single top-up. It's cheaper and simpler to stay on schedule.

How much do cat vaccinations cost in the UK?

Prices vary by region, practice and whether FeLV is included, but current UK figures give a useful range:

| Vaccination | Typical UK cost | | --- | --- | | Kitten primary course (two injections) | £50-£90 | | Annual booster (core only) | £30-£55 | | Annual booster (core + FeLV) | £45-£75 |

Across the year, most owners pay somewhere around £60 for an annual booster including FeLV. Two things bring the cost down:

• Health-care plans. Many UK practices offer monthly plans that spread the cost of vaccinations, flea and worm treatment and check-ups. These often work out cheaper than paying à la carte.
• Low-cost charity vaccination. The PDSA and RSPCA offer reduced-cost vaccinations to owners on certain means-tested benefits — typically Universal Credit (with a housing or child element), Pension Credit, Income Support, income-based Jobseeker's Allowance or income-related Employment and Support Allowance. Check the charity's eligibility criteria and your local area's availability.

Weigh the cost against the alternative: treating a cat with cat flu or enteritis, if it can be treated at all, costs far more and carries no guarantee.

Do indoor cats need vaccinations?

Yes. This is the biggest misconception in cat care. An indoor cat still needs the core vaccines because:

• Panleukopenia virus is extremely hardy and can be carried into the home on your shoes, clothing and hands.
• Cat flu viruses are widespread, and a stressed indoor cat can still fall ill.
• If your cat ever needs to go into a cattery, to the vet for a stay, or escapes outside, they need to be protected in advance.

What an indoor-only cat with no contact with other cats may reasonably skip is FeLV, since it only spreads through direct feline contact. That's a conversation to have with your vet rather than a decision to make alone.

Vaccinations and catteries

If you ever plan to board your cat, vaccination isn't just sensible — it's usually compulsory. Reputable catteries require an up-to-date vaccination record before they'll take a cat, and they'll want the boosters done well in advance of the stay, not the day before, so immunity has time to build. Book the booster at least a couple of weeks ahead of any holiday. The same applies if you use a home boarder registered under an animal-activity licence.

A pre-appointment checklist

Before your cat's vaccination visit:

• Bring the vaccination record card (or ask for one if it's the first visit) and keep it safe — you'll need it for catteries, insurance and travel.
• Note any changes in health since the last visit; the annual booster doubles as a health check.
• Tell your vet about your cat's lifestyle — indoor, outdoor, multi-cat home, or any planned travel or boarding — so they can advise on FeLV and rabies.
• Confirm which components are due this year, so you understand what you're paying for.
• Use a secure cat carrier and, for anxious cats, a calm-inducing spray or a towel over the carrier to reduce stress on the experience.

Adopting an adult cat with unknown history

Rehomed and stray cats often arrive with no paperwork, so you can't assume they're protected. A vet will usually treat an adult cat with an unknown vaccination history the same way as an unvaccinated one: a primary course of two injections three to four weeks apart, then annual boosters. It's a small cost for peace of mind, and most rescues, including Cats Protection and the RSPCA, vaccinate cats before rehoming and pass on the record — so ask for it. If you're introducing the new cat to existing cats, keeping them separated until the newcomer is health-checked and, ideally, tested for FeLV protects the whole household.

Multi-cat households

The more cats under one roof, the higher the stakes. Infectious diseases spread fastest where cats share food bowls, litter trays and grooming, so FeLV and cat flu protection matter more in a busy household. Keep every cat on the same booster rhythm, quarantine any new arrival until they're checked, and mention the multi-cat setup to your vet — it can change their FeLV recommendation for cats you might otherwise consider low-risk.

Are cat vaccines safe?

Modern cat vaccines have a strong safety record, and the risk from the diseases they prevent vastly outweighs the small risk from the jab. Mild, short-lived reactions can happen — a little tiredness, a slightly sore injection site or reduced appetite for a day. Serious reactions are rare. If your cat seems very unwell after a vaccination — persistent vomiting, facial swelling or breathing difficulty — contact your vet promptly. If you have a cat with a history of reactions or a specific health condition, discuss the vaccination plan with your vet rather than skipping protection entirely.

The bottom line

Every UK cat needs core protection against cat flu and enteritis, kept up with regular boosters; most cats that go outdoors also need FeLV. Start kittens at 8-9 weeks, complete the two-dose course, keep them in until it's finished, then book the annual check every year without fail. It's a modest, predictable cost that prevents diseases which are anything but modest.
