Cat Vaccination Guide Singapore: Schedules, Costs & Indoor Cat Vaccines

Does your indoor cat really need vaccinations? When should a kitten receive its first injection? And how much does cat vaccination cost in Singapore?

Whether you've just adopted a kitten or are wondering if your adult cat needs another booster, understanding feline vaccinations can feel confusing.

The answer isn't always as simple as giving every cat an injection once a year.

Different vaccines protect against different diseases. A kitten's vaccination requirements differ from an adult cat's, and a strictly indoor cat may need a different vaccination plan from one that regularly boards, goes outdoors or interacts with unfamiliar cats.

At The Cat Vet, a dedicated cat-only veterinary clinic in Pandan Valley, Singapore, we believe that preventive healthcare should be tailored to each cat's individual needs.

This guide explains which vaccinations cats need in Singapore, recommended vaccination schedules, costs, and what indoor-cat owners should know.

Cat Vaccination in Singapore: The Quick Answer

Cats in Singapore should receive core vaccinations against feline panleukopenia, feline herpesvirus and feline calicivirus—even if they live entirely indoors.

These vaccines are commonly administered together as a combination vaccine known as FVRCP, or sometimes described as a three-in-one cat vaccine.

The general vaccination schedule is:

Cat's age or situation	Recommended vaccination
6–8 weeks	First FVRCP vaccination
Every 2–4 weeks thereafter	Additional kitten FVRCP doses
16 weeks or older	Final dose of the initial kitten series
Around 6 months or within 12 months after the kitten series	First follow-up FVRCP booster, depending on the veterinary protocol
Adult cats	Risk-based booster schedule determined by the veterinarian
Adult cat with unknown history	Typically a two-dose initial FVRCP course, 2–4 weeks apart, under Singapore guidance

The appropriate schedule depends on previous vaccinations, the vaccine product used, lifestyle, health and exposure risk.

Singapore's vaccination guidelines recognise that adult cats may not necessarily require the same booster frequency throughout their lives.

Important: A three-year booster interval may be suitable for some low-risk adult cats under international guidance, but Singapore-registered vaccine labels may specify annual revaccination. Your veterinarian should discuss which protocol is appropriate for your cat.

1. What Vaccines Do Cats Need in Singapore?

Vaccines are broadly classified as core and non-core.

Core vaccines protect against important infectious diseases for which vaccination is recommended regardless of whether a cat lives indoors or outdoors.

Non-core vaccines are considered according to factors such as lifestyle, other cats in the household, exposure to unfamiliar animals and travel.

The Three Core Cat Vaccines: FVRCP

The FVRCP combination vaccine protects against three major feline viral diseases.

Disease	What it can cause	Why vaccination matters
Feline panleukopenia (FPV)	Severe gastrointestinal illness, dehydration and potentially fatal disease	Highly contagious; virus can persist in contaminated environments
Feline viral rhinotracheitis (FHV-1)	Sneezing, nasal discharge, eye disease and recurrent respiratory symptoms	Infection can persist in a latent state and reactivate during stress
Feline calicivirus (FCV)	Respiratory illness, oral ulcers, fever and sometimes severe disease	Can spread between cats through secretions and contaminated objects

These three infections are identified as core vaccine targets in Singapore's national veterinary vaccination guidelines.

Vaccination is particularly important because cats may encounter infectious agents even when their owners make considerable efforts to keep their homes clean and safe.

Does FVRCP Prevent Every Infection?

No vaccine provides absolute protection in every cat.

FVRCP vaccination generally provides strong protection against feline panleukopenia when an appropriate immune response develops.

Protection against feline herpesvirus and calicivirus is more complex. Vaccinated cats may still become infected or show respiratory symptoms, but vaccination can reduce the severity of disease.

This is one reason vaccination should be viewed as part of a broader preventive healthcare plan rather than a guarantee that a cat will never become ill.

2. Do Indoor Cats Need Vaccinations in Singapore?

Yes. Indoor cats should still receive their core FVRCP vaccinations.

Living indoors generally reduces a cat's exposure to infectious diseases, but it does not eliminate every possible route of transmission.

Singapore's feline vaccination guidelines specifically acknowledge that indoor cats can still encounter pathogens introduced through contaminated objects, clothing or footwear.

Several situations can create additional exposure risks:

• Bringing home a newly adopted kitten or cat whose vaccination history is unknown.

• Boarding your cat while travelling.

• Accidental escapes through doors or windows.

• Visiting veterinary clinics or other environments where animals are present.

• Sharing a home with cats that have outdoor access or uncertain infection status.

Feline panleukopenia is particularly concerning because its virus can remain infectious in contaminated environments for extended periods.

What Vaccines Does a Strictly Indoor Cat Need?

For a healthy adult cat living entirely indoors in a single-cat household, the typical priorities are:

Core FVRCP vaccination: Recommended, with booster frequency determined by vaccination history, vaccine product and risk assessment.

Feline leukaemia virus (FeLV): May not require ongoing vaccination if the adult cat has no meaningful exposure risk. Kittens require a separate discussion because international guidelines place greater emphasis on FeLV vaccination in younger cats.

Rabies: Not routinely required for a non-travelling pet cat in Singapore.

Being an indoor cat is therefore a reason to personalise the vaccination schedule, not to eliminate vaccinations altogether.

3. Kitten Vaccination Schedule in Singapore

Kittens require a series of vaccinations because the immunity they receive from their mother gradually declines.

These maternal antibodies can initially protect kittens against certain infections, but they can also interfere with the response to vaccination.

As a result, one vaccine dose given at a young age may not produce reliable, lasting protection.

Recommended FVRCP Vaccination Timeline

Age	Vaccination milestone
6–8 weeks	Begin the initial FVRCP vaccination series
9–12 weeks	Continue FVRCP boosters at 2–4-week intervals
12–16 weeks	Continue the series according to the veterinarian's schedule
At least 16 weeks	Give the final dose of the initial kitten series
Approximately 6–12 months later	Follow-up booster, according to the selected protocol

The schedule above is illustrative. Not every kitten receives the same number of injections, and the precise dates depend on when vaccination begins.

Singapore's local guidelines recommend starting at 6–8 weeks and repeating core vaccinations every 2–4 weeks until at least 16 weeks of age.

Updated international guidelines also support considering a follow-up vaccination from approximately 26 weeks of age, rather than necessarily waiting until the first annual booster.

Can Kittens Go Outside Before Completing Vaccinations?

Kittens that have not completed their initial vaccination series may remain susceptible to important infectious diseases.

Until your veterinarian confirms that appropriate protection has developed, avoid unnecessary exposure to unfamiliar or unvaccinated cats and potentially contaminated environments.

However, protecting a kitten from infection does not mean avoiding all positive social experiences. Safe handling, carrier training and gentle acclimatisation to everyday household activities remain important.

Ask your veterinarian how to balance disease prevention with healthy behavioural development.

4. How Often Do Adult Cats Need Booster Vaccinations?

Not every adult cat necessarily needs the same FVRCP booster schedule.

Vaccination intervals should be based on the cat's age, health, previous vaccinations, lifestyle, and the vaccine's licensed instructions.

Annual vs Three-Year Cat Vaccinations

You may have encountered different recommendations online.

Some veterinary clinics discuss annual boosters, while international guidelines describe intervals of three years or longer for certain low-risk adult cats.

Both recommendations need context.

In Singapore, the local veterinary vaccination guidelines note that core vaccine products were registered for annual booster intervals. They also recognise evidence of longer-lasting immunity and allow veterinarians to consider alternative schedules following an individual assessment and discussion with the owner.

The 2024 World Small Animal Veterinary Association (WSAVA) guidelines recommend revaccinating appropriately vaccinated, low-risk adult cats with certain modified-live core vaccines no more frequently than every three years.

However, higher-risk cats may benefit from more frequent vaccination, particularly against feline respiratory viruses.

Which Cats May Need More Frequent Vaccination?

A veterinarian may recommend a shorter interval for cats that:

• Regularly stay at boarding facilities.

• Have frequent contact with unfamiliar cats.

• Spend time outdoors.

• Live with cats of uncertain vaccination status.

• Have other circumstances that increase infectious disease exposure.

The key principle: Your cat should receive the vaccinations it needs, at intervals appropriate to its individual circumstances—not simply every available vaccine at every visit.

Regardless of booster frequency, adult cats should continue to have routine veterinary health assessments.

5. What if My Adult Cat Has Never Been Vaccinated?

It's not too late to discuss vaccination.

An adult cat with an unknown vaccination history may still benefit from an initial course of core vaccines.

Singapore's vaccination guidelines recommend two initial doses of modified-live core vaccines, administered 2–4 weeks apart, for adult cats whose history is unknown.

For previously vaccinated cats that have missed boosters, a veterinarian may recommend a different catch-up schedule after reviewing their records and the vaccine type.

Avoid assuming that a cat must restart its entire kitten vaccination series simply because several years have passed.

Your veterinarian can assess the circumstances and recommend the most appropriate approach.

6. How Much Does Cat Vaccination Cost in Singapore?

Published Singapore veterinary clinic prices show that a routine FVRCP vaccination may cost approximately S$15–S$60 for the vaccine service itself, depending on what is included.

Some clinics charge separately for consultation, while others include a pre-vaccination health assessment in the vaccination fee. A clinic quoting a low vaccine-only price may charge an additional consultation fee. Another clinic may charge more for the vaccination appointment but include a relevant health check. Prices also vary by vaccine brand, combination, package and individual medical requirements.

Confirm current charges directly with the clinic before booking.

How Much Should You Budget for Kitten Vaccinations?

The total cost depends on:

• How many FVRCP doses your kitten requires.

• The age at which vaccination begins.

• Whether consultations are included.

• Whether FeLV vaccination is recommended.

• Any additional medical assessment or tests.

For budgeting purposes, request an itemised estimate for the complete kitten vaccination programme, rather than only the first injection.

At The Cat Vet, you can contact our team to discuss your kitten's vaccination requirements and obtain current pricing.

7. Does My Cat Need the Feline Leukaemia (FeLV) Vaccine?

Feline leukaemia virus, or FeLV, is an infectious virus that can affect a cat's immune system and contribute to serious illness.

It spreads mainly through close contact with infected cats, including sustained social interactions, grooming and exposure to infected secretions.

Is FeLV a Core Vaccine in Singapore?

Under Singapore's local vaccination guidelines, FeLV is classified as a non-core vaccine.

Vaccination is recommended for cats with increased exposure risk.

Examples include cats that spend time outdoors or live with cats whose FeLV infection status is unknown.

International guidance places additional emphasis on vaccinating kittens and cats younger than one year because younger cats are generally more susceptible to progressive infection.

Consequently, veterinarians may recommend discussing FeLV vaccination even when a kitten is expected to become an indoor-only adult.

FeLV Vaccination Schedule

For cats in which FeLV vaccination is appropriate:

Stage	Typical recommendation
Before vaccination	FeLV testing
First dose	From 8 weeks of age
Second dose	3–4 weeks after the first
First follow-up booster	Approximately 12 months after completion of the initial series
Subsequent boosters	Based on exposure risk and veterinary assessment

Cats should be tested before their first FeLV vaccination because vaccination is not a treatment for an existing FeLV infection.

For a healthy, strictly indoor adult cat with no exposure to FeLV-positive or unknown-status cats, continued FeLV vaccination may not be necessary.

8. Is Rabies Vaccination Required for Cats in Singapore?

Rabies vaccination is not compulsory for ordinary pet cats living in Singapore.

According to the Animal & Veterinary Service (AVS), Singapore has remained rabies-free since 1953.

Rabies vaccination is encouraged but not mandatory for resident pets.

Singapore's local vaccination guidelines classify rabies vaccination as non-core and do not routinely recommend it for cats that are not travelling overseas.

However, rabies vaccination can become an important requirement when importing, exporting or travelling internationally with a cat.

Different destinations have their own conditions, including vaccination validity periods and possible rabies antibody testing.

If you plan to relocate or travel with your cat, speak to your veterinarian well in advance.

Important: Cat licensing and rabies vaccination are different requirements. Pet cats in Singapore must be licensed under AVS rules, but routine rabies vaccination is not a general condition for keeping a resident cat.

9. What Are the Side Effects of Cat Vaccinations?

Most cats tolerate routine vaccinations without significant problems.

When side effects occur, they are usually mild and temporary.

Possible reactions include:

• Mild tiredness or reduced activity.

• Temporary loss of appetite.

• Mild discomfort at the injection site.

• A small swelling around the injection area.

• Temporary low-grade fever.

Contact your veterinarian if symptoms persist, worsen or concern you.

When Is a Reaction an Emergency?

Seek urgent veterinary care if your cat experiences difficulty breathing, collapse, marked facial swelling, repeated vomiting or other signs of a severe allergic reaction following vaccination.

Serious reactions are uncommon, but prompt treatment is important.

Any injection-site lump that persists, grows or changes should also be assessed by a veterinarian. Do not assume every lump following vaccination is harmless.

Your veterinary team can explain what to monitor and how long observation is appropriate.

10. Should Senior Cats Still Be Vaccinated?

Age alone does not automatically mean a cat should stop receiving vaccinations.

Senior cats may still be susceptible to vaccine-preventable diseases, particularly when their vaccination history is incomplete or their exposure risk changes.

However, vaccination decisions should take into account the cat's health, medical conditions, current medications, previous vaccine reactions and lifestyle.

For some older, low-risk cats, a veterinarian may recommend adjusted booster intervals or discuss antibody testing for selected diseases.

Annual health examinations remain important even when vaccination is not due.

A senior cat's preventive healthcare plan should also address issues such as dental health, weight changes, kidney health and other age-related conditions.

11. Can Antibody Titre Tests Replace Vaccinations?

Antibody titre testing measures antibodies in the blood against a particular infectious agent.

For feline panleukopenia, certain antibody tests can help veterinarians assess whether a cat has evidence of protective immunity.

This can be useful in selected situations, such as when a cat has previously experienced a vaccine reaction.

However, titre testing has important limitations.

Antibody testing is less reliable for making decisions about protection against feline herpesvirus and calicivirus, because immunity against these infections involves mechanisms that are not adequately represented by a simple blood antibody measurement.

Titre testing is therefore not a universal replacement for FVRCP vaccination.

Discuss its benefits, limitations and cost with your veterinarian before deciding whether it is appropriate.

12. Frequently Asked Questions About Cat Vaccinations in Singapore

What is the three-in-one cat vaccine in Singapore?

The three-in-one cat vaccine, commonly called FVRCP, protects against feline panleukopenia, feline herpesvirus and feline calicivirus. These are the three core feline vaccine components recognised by Singapore's vaccination guidelines.

How many vaccinations does a kitten need?

The number depends on when vaccination begins. Core vaccination generally starts at 6–8 weeks, with additional doses every 2–4 weeks until at least 16 weeks of age. Your veterinarian will calculate the number of appointments based on your kitten's age and individual circumstances.

Do indoor cats need yearly vaccinations?

Indoor cats still need core vaccines, but annual FVRCP vaccination is not automatically necessary for every adult cat. Some low-risk cats may be suitable for extended booster intervals, depending on the vaccine product, vaccination history, local licensing conditions for that product and veterinary assessment.

How much is a cat vaccination in Singapore?

Published clinic examples range from S$14.30 for a feline vaccine excluding consultation at Evervet to S$58 for FVRCP including a vaccination-related health check at SingVet. Total costs vary, so confirm whether the quotation includes a consultation and any additional services.

Is rabies vaccination compulsory for cats in Singapore?

No. AVS states that rabies vaccination is encouraged but not compulsory for resident pets. International travel or import conditions may require it.

Does my indoor cat need an FeLV vaccine?

Not necessarily throughout adulthood. FeLV vaccination is risk-based in Singapore, and a strictly indoor adult cat living only with FeLV-negative cats may not require ongoing boosters. Kittens and cats with possible exposure should be assessed individually.

Can I vaccinate a cat that has missed several years of boosters?

Yes, catch-up vaccination may be appropriate. The recommended course depends on the cat's documented vaccination history, vaccine type, health and exposure risk. Your veterinarian can determine whether a single booster or a different schedule is required.

Can I vaccinate my cat when it is sick?

Your veterinarian should assess your cat before vaccination. Vaccination may be deferred depending on the illness, its severity and other medical factors. Special circumstances, such as high-risk shelter environments, require different risk–benefit considerations.

Can an FVRCP-vaccinated cat still get cat flu?

Yes. Vaccination against feline herpesvirus and calicivirus does not guarantee prevention of infection. Vaccinated cats can still develop respiratory signs, but vaccination may reduce disease severity.

Where can I vaccinate my cat in Singapore?

Routine feline vaccination is available through veterinary clinics in Singapore. The Cat Vet is a dedicated cat-only veterinary clinic located at 2 Pandan Valley, #B1-204D, Singapore 597626. Contact the clinic to discuss an appropriate vaccination plan and current fees.

Protecting Your Cat Starts With the Right Vaccination Plan

Vaccinations are an important part of protecting cats against preventable infectious diseases.

But good preventive healthcare goes beyond following a fixed schedule.

A kitten beginning its vaccinations, a healthy indoor adult cat and a senior cat with existing medical conditions may all require different approaches.

At The Cat Vet, we focus exclusively on cats and understand that their healthcare needs change throughout life.

Our veterinary team can review your cat's vaccination history, assess its lifestyle and help you understand which vaccines are appropriate.

Because protecting your cat isn't about giving more injections than necessary.

It's about providing the right protection, at the right time.
