Protecting Your Cat with Vaccines

Vaccinations are a vital part of your cat’s lifelong health care. They protect against contagious and potentially life-threatening diseases, some of which can also affect people. At The Animal Hospital of Roxbury, we recommend vaccines based on your cat’s age, health, and lifestyle—whether they’re an indoor snuggler, an adventurous outdoor explorer, or somewhere in between.

  • Rabies – Protects against a fatal virus that can be transmitted to humans. Required by law, this vaccine is essential for your cat’s safety and the safety of your family.

  • FVRCP – A combination vaccine that guards against three serious viruses: Feline Viral Rhinotracheitis, Calicivirus, and Panleukopenia. Together, these protect your cat from severe respiratory, oral, and gastrointestinal diseases.

  • Feline Leukemia (FeLV) – Recommended for cats who go outdoors or have potential exposure to other cats. This vaccine helps prevent a viral disease that weakens the immune system and can lead to life-threatening illness.

By keeping your cat’s vaccines up to date, you’re not only protecting their health but also helping prevent the spread of disease in our community. Our team will create a vaccination plan tailored to your cat’s needs and lifestyle.

Frequently Asked Questions

What vaccines does my cat need?
Most cats need core vaccines—rabies and FVRCP (feline viral rhinotracheitis, calicivirus, and panleukopenia)—plus non-core vaccines like feline leukemia (FeLV) depending on their lifestyle and exposure risk.

What are core vaccines for cats?
Core vaccines protect against diseases that are widespread, severe, and sometimes contagious to humans. For cats, these are rabies and FVRCP.

What are non-core vaccines for cats?
Non-core vaccines are recommended based on a cat’s lifestyle. The most common is Feline Leukemia (FeLV), which is especially important for cats who go outdoors or interact with other cats.

What cat vaccinations are required by law?
Rabies vaccination is required by law in most states, regardless of whether your cat lives indoors or outdoors.

When should I start vaccinating my kitten?
Kittens typically begin vaccines at 6–8 weeks old and receive boosters every 3–4 weeks until they are about 16 weeks old.

How often does my cat need booster vaccinations?
Booster schedules vary, but many adult cats receive core vaccines every 1–3 years depending on the vaccine type, your cat’s age, and health.

What are the benefits of vaccinating my cat?
Vaccines protect your cat from serious illnesses, help prevent the spread of contagious diseases, and protect your family from zoonotic diseases like rabies.

Are there any risks or side effects associated with cat vaccines?
Most cats tolerate vaccines very well. Mild side effects may include soreness, tiredness, or a low fever. Rare but serious reactions—such as swelling, vomiting, or breathing trouble—require immediate veterinary attention.

How do I know if my cat is up-to-date on vaccinations?
Your veterinary team keeps detailed records. You can also ask for a printed or digital copy of your cat’s vaccine history. Our PetPage App allows you to access your vaccine record at any time. 

Can my cat receive multiple vaccines at once?
Yes. Administering more than one vaccine in the same visit is common and safe, but your vet will tailor the schedule based on your cat’s health.

What should I do if my cat has a reaction to a vaccine?
Call your veterinarian immediately if you notice facial swelling, hives, vomiting, diarrhea, or difficulty breathing.

How do I prepare my cat for a vaccination appointment?
Bring your cat in a secure carrier, keep them calm, and let us know about any health changes or previous vaccine reactions.

Can indoor cats skip certain vaccinations?
Even indoor cats should receive core vaccines. Rabies is legally required, and respiratory viruses can enter the home on clothing, shoes, or through open windows.

How do vaccinations help prevent feline diseases?
Vaccines train your cat’s immune system to recognize and fight viruses or bacteria before they cause serious illness.

What is the difference between a vaccine and a titer test for cats?
A vaccine stimulates immunity. A titer test measures antibodies in the blood to determine if your cat may still be protected from a previous vaccination.

Are there any specific vaccines recommended for senior cats?
Senior cats may still benefit from core vaccines, but your vet will adjust the schedule based on their health and risk factors.

Can my cat be vaccinated if it has a health condition?
Your vet will determine if it’s safe. In some cases, vaccines may be delayed or given with special precautions.

What vaccines are required for boarding or traveling with my cat?
Most boarding facilities require rabies and FVRCP. Some may also require FeLV for cats with outdoor access. Airline and international travel may have additional requirements.

What is the cost of cat vaccinations, and is it covered by pet insurance?
Prices vary depending on the vaccines needed. Some pet insurance plans cover preventive care, while others focus only on illness and injury.

How can I find a reputable vet for my cat’s vaccinations?
Look for a licensed veterinarian with good reviews, a clean and cat-friendly facility, and a team that communicates clearly.

What happens if I don’t want to vaccinate my cat?
Skipping vaccines puts your cat at risk for serious illness and may violate local rabies laws. It can also limit boarding, travel, or grooming options.
