Should I get my indoor cat vaccinated?

Vaccinations are very important. And that's true even for indoor cats. In this post, our Villa Rica veterinarians talk about vaccines for cats and why it's important to vaccinate your indoor cat.

What are cat vaccinations?

Certain cat-specific diseases can make many cats sick. Getting your kitten vaccinated is crucial for their protection. Booster shots are necessary to ensure the safety of your indoor cat. Regular booster shots are crucial for your kitten's health, even if they will be an indoor cat.

Why should I vaccinate my indoor cat?

Many states require certain vaccinations for indoor cats, even if you believe they are unnecessary. Rabies vaccinations are required in several states for cats over the age of six months. Following the vaccinations, your veterinarian will give you a vaccination certificate. Remember to store it securely.

When thinking about your cat's health, it's wise to be cautious, as cats are naturally curious creatures. Our Villa Rica veterinarians recommend core vaccinations for indoor cats to shield them from diseases they might encounter if they ever venture outside. 

What happens if I don't vaccinate my indoor cat?

If you choose not to vaccinate your indoor cat, they will be at risk of contracting various diseases such as feline leukemia, rabies, and upper respiratory infections. These diseases can be transmitted through contact with other animals, objects, or even humans. Regular vaccinations are essential to protect your cat's health and prevent the spread of these illnesses.

Cat Vaccines

There are two basic types of vaccinations available for cats.

Core vaccinations should be given to all cats because they are key for protecting them from the following common but serious feline conditions:


Rabies kills many mammals (including humans) every year. These vaccinations are required by law for cats in most states.

Feline Viral Rhinotracheitis, Calicivirus and Panleukopenia (FVRCP)

Typically known as the "distemper" shot, this combination vaccine protects against feline viral rhinotracheitis, calicivirus, and panleukopenia.

Feline herpesvirus type I (FHV, FHV-1)

This virus is highly contagious and can be found anywhere. It makes a significant contribution to upper respiratory infections. The virus can spread through a variety of means, including sharing litter trays or food bowls, inhaling sneeze droplets, and coming into direct contact. Cats can be infected with the virus throughout their lives. Some people continue to shed the virus, and a persistent FHV infection can cause vision problems.

Non-core vaccinations are recommended for some cats based on their lifestyle. Your vet will offer you advice on which non-core vaccines your cat should get. These can protect your cat from:

Feline immunodeficiency virus (FIV) and Feline Leukemia (FeLV)

These vaccines protect against viral infections that are transmitted via close contact. They are only usually recommended for cats that spend time outdoors.


This bacteria causes upper respiratory infections that are highly contagious. Your vet may recommend this vaccine if you are taking your cat to a groomer or boarding kennel.

Chlamydophila felis

Chlamydia is a bacterial infection that causes severe conjunctivitis. The vaccination for the infection is often included in the distemper combination vaccine.

When should my kitten get their first shots?

Take your kitten to the vet for their first vaccinations when they're around 6-8 weeks old. After that, keep bringing them back every 3-4 weeks until they're about 16 weeks old for more shots.

Indoor Cat & Kitten Vaccination Schedule

First visit (6 to 8 weeks)

  • Fecal exam for parasites
  • Blood test for feline leukemia
  • Review nutrition and grooming
  • Vaccinations for chlamydia, calicivirus, rhinotracheitis and panleukopenia

Second visit (12 weeks)

  • Examination and external check for parasites
  • First feline leukemia vaccine
  • Second vaccinations for calicivirus rhinotracheitis and panleukopenia

Third visit (follow veterinarian's advice)

  • The second feline leukemia vaccine
  • Rabies vaccine

When will my cat require booster shots?

Adult cats need booster shots, which can be either yearly or every three years, depending on the type of vaccine. Your vet will let you know when to schedule these shots for your cat. 

Will my kitten be protected after their first round of shots?

It is critical that your kitten receive multiple vaccinations to ensure complete protection. These vaccinations are usually given when your kitten is between 12 and 16 weeks old. Once your kitten has received their initial vaccinations, they will be protected from the conditions or diseases covered by the vaccines. 

Let your kitten outside before they finish their hots, but stick to safer places like your own backyard.

Are there potential side effects of cat vaccinations?

Most cats won't display any side effects after getting their vaccines. If your kitty does develop a reaction, they are typically short in duration and minor. But keep in mind these potential negative side effects:

  • Loss of appetite
  • Redness or swelling around the injection site
  • Severe lethargy
  • Lameness
  • Hives
  • Diarrhea
  • Fever
  • Vomiting

If you suspect your cat is reacting badly to a vaccine, contact your vet immediately. They can check if your kitty needs extra care.
