What Vaccinations Should My Cat Get? A Complete UK Guide to Cat Vaccines & Boosters

Vaccinations are an essential part of being a responsible cat owner. Whether your cat stays indoors or spends most of its time wandering the neighbourhood, these vaccines protect against serious, highly contagious, and often fatal diseases.

Common questions for cat owners include:

• Does my indoor cat really need them?

• How often are boosters required?

In this guide, we answer these questions and more, providing insight into the exact vaccines and schedules so you know what your cat actually needs to stay healthy.

Why Are Cat Vaccinations Important?

Vaccines stimulate the immune system to recognise and fight disease. There are many feline diseases that threaten domestic cats, and they can be extremely contagious, very difficult to treat and potentially fatal.

Vaccinations are crucial to prevent the spread of these diseases between cats. They are particularly important in:

• Multi-cat households

• Catteries

• Outdoor environments

You may be put off by the cost of getting your cat vaccinated, but rest assured it is cheaper than getting treatment for a serious illness, which can potentially cost hundreds to thousands of pounds.

You will find that most cat boarding centres and pet insurance policies require you to have full vaccinations for your cat.

What Vaccinations Should My Cat Get?

Now we get on to the core theme of this article: what vaccinations should your cat get? Your vet will guide you on this, but it helps to understand the most common types and what they are for.

Core Vaccinations (Recommended For All Cats)

Here are the vaccinations that are considered essential in the UK:

• Feline Parvovirus (FPV/Feline Panleukopenia): This is a virus that is highly contagious and often fatal. It attacks the immune system and gut, and it is particularly dangerous for kittens.

• Feline Herpesvirus (FHV-1): This is one of the main causes of cat flu. WHen a cat contracts it, they get a lifelong infection.

• Feline Calicivirus (FCV): Another major cause of cat flu, this can lead to mouth ulcers and respiratory issues.

These vaccines are often combined into a single cat flu + enteritis vaccination that your vet can administer.

Non-Core Vaccinations (Lifestyle-Dependent)

While not necessarily considered to be essential, these vaccines are often recommended based on specific risk factors for cats.

• Feline Leukaemia Virus (FeLV): This is a disease that spreads through saliva, close contact and bites. It weakens the immune system once a cat is infected, and is often fatal in the long-term. It is recommended for outdoor cats and cats that mix with others.

• Rabies (rare in the UK): This vaccination is not routine for most UK cats, but it is often required for international travel when you apply for a pet passport.

Do Indoor Cats Need Vaccinations?

Indoor cats need vaccinations. This is something that many people question, but it is a fact. Even if a cat spends its entire life indoors, there are still risks. For example, viruses can be carried indoors on shoes or clothing, or through contact with visitors and other pets.

It’s important to understand that cat flu viruses are highly transmissible. In some cases, FeLV may not be necessary for a cat that is strictly indoor-only - seek guidance from your vet for this.

For indoor cats, key benefits of getting vaccinations include:

• Enabling emergency boarding situations

• Maintaining flexibility if lifestyle changes

Kitten Vaccination Schedule (UK Guide)

Kittens are particularly vulnerable to feline illnesses due to their immature immune systems. This is why it is usually recommended to get their vaccinations as early as possible. The typical schedule looks like this:

• First injection: 8-9 weeks old

• Second injection: 12 weeks old

• Sometimes, a third dose will be needed, but this depends on timing.

You need to be aware that your kitten doesn’t attain full protection until after the second dose of the vaccine. It is strongly recommended to avoid letting kittens outdoors before full vaccination and that you keep them away from unvaccinated cats.

Adult Cat Booster Schedule: How Often Are Vaccines Needed?

For adult cats, the first booster comes 12 months after the kitten course. From there on, they will typically receive a booster every year for cat flu vaccines and one every 3 years for parvovirus.

The frequency of boosters ultimately depends on:

• The vaccine brand

• Vet recommendations

• The cat’s lifestyle

If a cat misses a booster, it may need to restart the full vaccination course. Also, immunity reduces over time, so it’s important to be mindful of this as your cat gets older.

What Happens During a Cat Vaccination Appointment?

When you take your cat for its vaccination appointment, it will get a full health check from the vet. This will include an assessment of its weight, its teeth, and its heart and lungs. Vets do this because a vaccine can only be administered if the cat is healthy.

Here are some key things for you to know about the process:

• The appointment typically lasts around 10-15 minutes.

• The injection is quick and causes very low discomfort - most cats barely notice it.

Are Cat Vaccinations Safe? (Side Effects Explained)

The vaccines given to cats are extensively tested and regulated, so you can rest assured they are safe to be given to your animal. There are a few common mild side effects that you may notice:

• Sleepiness

• Slight fever

• Reduced appetite

• A small lump at the injection site

In extremely rare cases, there have been allergic reactions to the vaccine, but this is very uncommon. If your cat keeps showing any of the above side effects for more than 24-48 hours, we recommend that you contact your vet and report it.

How Much Do Cat Vaccinations Cost in the UK?

The expense is something that many owners worry about when it comes to cat vaccinations. Though they may seem a lot, the fact that you only get them once per year means that they actually cost less than your streaming subscriptions.

The typical costs are as follows:

• Kitten course: £70-£100

• Booster: £40-£70 annually

The costs tend to vary depending on location, veterinary practice and the type of vaccine. It is a worthwhile expense because it prevents your cat from catching other diseases that are extremely costly to treat. Emergency cat care can easily exceed £1,000.

When Should You NOT Vaccinate Your Cat?

Vets advise against vaccinating cats in certain circumstances. If your cat is unwell or recovering from an illness, they will usually recommend that you wait until they have recovered before getting them vaccinated. If your cat is pregnant, consult the vet for advice.

You should always follow the expert guidance of your vet to ensure safety. Individual health assessments are essential for determining risks associated with vaccination and non-vaccination alike.

Quick Summary: What Vaccinations Does My Cat Need?

All cats should get their core vaccines, which cover parvovirus and cat flu. Some cats will also need the FeLV vaccine - usually if they are outdoor cats or socialise with other animals a lot. The timeline for these vaccinations is as follows:

• Start at 8-9 weeks

• Booster at 12 months

• Regular boosters thereafter

It is as simple as this, and will help to keep your cat in good health.

Final Thoughts

Vaccinations are one of the simplest and most cost-effective ways to protect your cat’s life. When you have a kitten or you get a new cat, speak to a vet for a tailored action plan. Whether indoor or outdoor, vaccination is a low-cost, high-impact decision for your cat’s welfare.
