Cat vaccinations are an important part of responsible pet ownership and help protect cats from preventable, potentially serious diseases. At A Gentle Vet, our goal is to provide clear, accurate guidance so you can make informed decisions about your cat’s care. Vaccines are a core component of an effective preventive care plan and are tailored to your cat’s age, health status, and lifestyle.

If your kitten or cat is due for vaccines, or if you have questions about what they need, please call us at (801) 968-9932 to schedule an appointment.

What Are Cat Vaccinations?

Vaccinations work by stimulating your cat’s immune system to recognize and respond to specific diseases. Vaccines contain inactivated organisms or components of viruses or bacteria, which allow the immune system to build protection without causing illness. For example, the rabies vaccine contains viral components that help your cat develop antibodies, so they can respond effectively if exposed in the future.

Are Cat Vaccinations Necessary?

Yes. Certain vaccines are considered essential for all cats and are referred to as core vaccines. Core vaccines typically include rabies and the FVRCP vaccine, which protects against feline viral rhinotracheitis, calicivirus, and panleukopenia (sometimes called feline distemper).

Other vaccines are recommended based on lifestyle and exposure risk. The feline leukemia virus (FeLV) vaccine is a common example and is often advised for kittens and cats that go outdoors or have contact with other cats.

Which Additional Vaccines May Be Recommended?

Kittens typically receive a broader set of vaccines to establish strong early immunity. Even if a kitten is expected to live indoors, the FeLV vaccine is often recommended during the kitten series. Lifestyle changes can occur, and early protection helps reduce risk if exposure happens later.

After the initial kitten series, your veterinarian will recommend an ongoing schedule based on your cat’s risk factors. This may include rabies and FVRCP boosters at extended intervals, and continued FeLV vaccination for cats with outdoor access or exposure to other cats.

What Is The Vaccination Schedule For Kittens?

Most kittens begin vaccinations between six and eight weeks of age. The FVRCP vaccine is typically given first, followed by booster doses every three to four weeks until around 16 weeks of age.

A rabies vaccine is usually administered around 12 weeks of age, depending on local regulations. The FeLV vaccine is commonly started during this period as well, especially for kittens that may have outdoor exposure or contact with other cats.

Your veterinarian will guide you through the timing and spacing of these vaccines to ensure appropriate immune protection.

What Is The Vaccination Schedule For Adult Cats?

Adult cats require ongoing vaccinations to maintain immunity. 

  • FVRCP boosters at intervals determined by vaccine type and risk
  • Rabies vaccination every one or three years, depending on the vaccine used
  • FeLV vaccination for cats with outdoor access or exposure to other cats

During routine wellness visits, your veterinarian will review your cat’s lifestyle and health status to confirm which vaccines are appropriate.

Are There Risks Or Side Effects Associated With Cat Vaccines?

Vaccines are generally very safe. Mild side effects such as temporary lethargy, reduced appetite, or localized soreness at the injection site are the most common and typically resolve within a day.

More serious reactions, such as facial swelling, vomiting, diarrhea, or severe lethargy, are uncommon and should be evaluated promptly. A rare condition known as feline injection-site sarcoma has been associated with vaccinations, but it occurs infrequently. This risk is one reason veterinarians carefully follow evidence-based vaccination schedules and avoid unnecessary boosters.

Do Indoor Cats Still Need Vaccinations?

Yes. Rabies vaccination is recommended even for indoor-only cats, as accidental exposure can still occur. FVRCP vaccination is also commonly advised for indoor cats due to the ease with which viral particles can be introduced into the home environment.

Why Is It Important Not To Miss A Cat Vaccination?

Delaying or missing vaccinations can reduce your cat’s immunity and increase their risk of disease. Staying on schedule through regular veterinary visits helps ensure consistent protection throughout your cat’s life.
