Key Points
Kittens need a series of core vaccines, including the FVRCP and rabies shots, starting as early as 6 weeks old and finishing around 16 weeks.
Your vet will recommend non-core vaccines like the feline leukemia (FeLV) vaccine based on your kitten's age, lifestyle, environment, and risk factors.
Staying on schedule matters. Missing or delaying shots can leave gaps in your kitten's protection during the most vulnerable stage of their life.
You’re ready for the kitten. You have the supplies. You’ve kitten-proofed the house. You may have even watched enough videos to consider yourself an expert. Then the kitten comes home, and you realize there’s one thing you can’t prepare for: how much this tiny creature now depends on you.
Suddenly, you’re in charge of everything from dinner to veterinary appointments. One of the first things you’ll need to figure out is their vaccination schedule: which shots they need, when they need them, and what happens at each visit. This kitten vaccination schedule video can help you learn the basics about their vaccines. Need more information? Keep reading!
How do kitten vaccines work?
Kitten vaccines work by introducing your kitten's immune system to a safe, weakened, or inactive form of a virus or bacteria. This triggers the body to build antibodies, so if your kitten encounters the real disease later, their immune system is already prepared to fight it off.
Kittens are born with some natural immunity passed on through their mother's milk, but that protection fades within the first few weeks of life. That's why the kitten vaccination schedule starts early, usually around 6 to 8 weeks, and requires multiple rounds of shots to build solid, lasting protection.
Each booster in the series isn't just a repeat. It strengthens the immune response. That's why skipping a round or stretching out the timeline can leave your kitten vulnerable.
Your vet will tailor the exact schedule based on your kitten's age, health, and living situation. But no matter what, core vaccines are considered an essential item on the new kitten checklist – for every kitten, indoor or outdoor.
What shots do kittens need?
Some vaccines are recommended for every kitten, while others depend on where your kitten lives, how much time they spend outside, and what kinds of feline friends they’ll have. Here’s what each vaccine does and when your kitten may need it.
FVRCP vaccine
The FVRCP vaccine is sometimes called the "feline distemper vaccine," but it actually protects against three separate diseases:
Feline viral rhinotracheitis (FVR): A highly contagious upper respiratory infection caused by feline herpesvirus. It can cause sneezing, nasal congestion, eye discharge, and fever.
Calicivirus (C): Another common respiratory virus that can lead to mouth ulcers, pneumonia, and joint pain.
Panleukopenia (P): Also known as feline distemper, this is a severe and often fatal virus that attacks the immune system and intestinal lining. It's especially dangerous for kittens.
The FVRCP is the most important vaccine in your kitten's schedule. It's given in a series of 3-4 doses, starting at 6 to 8 weeks old and finishing around 16 weeks. After that, your kitten will need a booster at 6 months to 1 year, then every 3 years going forward, typically given at one of your cat’s annual appointments.
Rabies vaccine
Rabies is a fatal viral disease that affects the brain and nervous system, and it can be transmitted to humans. Because of this, the rabies vaccine is required by law in most states, even for indoor cats, and protects everyone in your family.
Kittens typically get their first rabies shot at 14 to 16 weeks old. Depending on your state's requirements and the vaccine type your vet uses, boosters are given annually or every 3 years.
Feline leukemia (FeLV) vaccine
The feline leukemia virus suppresses the immune system and can lead to cancer, anemia, and secondary infections. It spreads through close contact with infected cats, such as sharing food bowls, grooming, or bite wounds.
The AAHA/AAFP Feline Vaccination Guidelines recommend FeLV vaccination for all kittens, regardless of lifestyle. Kittens are more susceptible to the virus than adult cats, and their future living situation may change. Your vet may recommend testing your kitten for FeLV before starting the vaccine series.
The FeLV vaccine is given in 2 doses: the first around 10 to 12 weeks and the second at 14 to 16 weeks. Whether your cat continues to receive FeLV boosters as an adult depends on their risk level.
Non-core vaccines
Some kittens need a few extra vaccines depending on their lifestyle, where they live, and what kinds of adventures they’re likely to get into. Your vet can help you decide which ones make sense for your kitten.
These include:
Chlamydia felis: Protects against a bacterial infection that causes conjunctivitis and upper respiratory symptoms. Often recommended for kittens in multi-cat environments.
Bordetella bronchiseptica: Guards against a bacterial respiratory infection. May be recommended for kittens who will be boarded or in shelters.
Feline immunodeficiency virus (FIV): According to the Cornell Feline Health Center, no FIV vaccine has been commercially available in North America since 2016. Talk to your vet if your cat will have outdoor access.
Kitten vaccination schedule by age
Here's a general cat vaccination schedule showing which vaccines are typically given at each stage. Keep in mind that your vet may adjust the timing based on your kitten's health and history.
Age | Vaccines | Notes |
6 to 8 weeks | FVRCP (1st dose) | Protects against feline herpesvirus, calicivirus, and panleukopenia, three serious diseases that can be especially dangerous for kittens. |
10 to 12 weeks | FVRCP (2nd dose) FeLV (1st dose) | Builds on the first FVRCP dose and starts protection against feline leukemia virus (FeLV). |
14 to 16 weeks | FVRCP (3rd dose) Rabies FeLV (2nd dose) | Completes the initial FVRCP series and continues FeLV protection. Rabies vaccination protects against a fatal disease that can also spread to people. |
6 months-1 year | FVRCP booster Rabies booster | Boosters help maintain protection as your kitten grows into adulthood. |
6 to 8 weeks: first FVRCP shot
This is when most kittens get their first shot. The maternal antibodies from their mother's milk are starting to wear off, so it's the ideal time to begin building their own immunity.
At this age, your vet will also do a full wellness exam, checking weight, heart, lungs, ears, and eyes.
10 to 12 weeks: second round of shots
At this visit, your kitten gets the second FVRCP dose along with the first FeLV vaccine. Your vet may also start discussing cat deworming, flea prevention, and spay/neuter timing.
14 to 16 weeks: final kitten boosters and rabies
This is the big visit. Your kitten gets their final FVRCP booster, first rabies shot, and second FeLV dose. After this round, your kitten's core vaccine series is complete.
Your vet will likely discuss a long-term care plan at this visit, including when to come back for 1-year boosters, ongoing parasite prevention, and nutrition guidance. Depending on your kitten's lifestyle, they may also recommend any non-core vaccines at this time.
6-month to 1-year boosters and beyond
That first year goes by quickly, and before you know it, your tiny kitten is growing into a cat. About 6-months to a year after the initial kitten vaccine series, they’ll need FVRCP and rabies boosters to keep their protection going.
Some vets give this booster at about 6 months instead of waiting until 1 year to close the possible immunity gap from maternal antibody interference.
Your vet may also recommend continuing FeLV vaccination every year if your cat goes outdoors or lives with other cats. And as your kitten grows up, regular vet visits remain an important part of keeping them healthy and catching potential problems early.
Do indoor kittens need vaccines?
Yes. Indoor kittens still need core vaccines. They can be exposed through accidental escapes, visiting pets, contaminated shoes or clothing, or future lifestyle changes. Rabies vaccination may also be required by local law, even for indoor cats.
Indoor cats can still be exposed to viruses. You can carry pathogens in on your shoes, clothing, or hands. A door or window left open for even a moment could lead to an escape. And if you ever need to board your cat, visit the vet, or introduce a new pet into the home, your cat's vaccine protection becomes critical.
The guidelines are clear: core vaccines are recommended for all cats, regardless of indoor or outdoor status. Your vet may recommend skipping certain non-core vaccines, like FeLV boosters after the kitten series, if your cat is strictly indoors with no exposure to other cats. But core vaccines are non-negotiable for most kittens.
According to UC Davis vaccination guidelines, the benefits of core vaccination far outweigh the minimal risks, even for cats with low exposure.
How much do kitten vaccines cost?
Along with knowing what your kitten needs, it helps to know what those early vet visits may cost. The national average cost of kitten vaccines runs about $25 to $60 per vaccine, though prices vary by location and clinic.
Individual vaccine costs break down roughly like this:
FVRCP: about $34 per dose
Rabies: about $31
FeLV: about $42 per dose
Non-core vaccines: typically fall within the same $22 to $62 range
Keep in mind, vaccine costs typically don't include the exam fee, which can add $50 to $75 per visit, and vaccinations are not typically covered by pet insurance.
Side effects of kitten vaccines
Most kittens handle their vaccines with no issues at all. But mild side effects are normal and usually clear up within 24 to 48 hours.
Here's what to watch for:
Mild lethargy or decreased appetite: Your kitten may sleep more or eat less for a day or two.
Slight fever: A low-grade fever is a sign the immune system is responding.
Soreness at the injection site: A small, firm bump where the shot was given is common and usually resolves on its own.
Mild sneezing: Especially with intranasal vaccines.
In rare cases, kittens can have more serious reactions. Contact your vet right away if you notice:
Swelling of the face, ears, or eyes
Persistent vomiting or diarrhea
Difficulty breathing
Collapse or extreme weakness
A lump at the injection site that grows or persists for more than 3 weeks
Serious allergic reactions are uncommon but can happen within minutes to hours after vaccination. If your kitten has had a reaction to a vaccine before, let your vet know. They can adjust the plan or pre-treat with antihistamines.
Keeping your kitten healthy from the start
Bringing home a kitten means suddenly having a very small, very curious creature counting on you for just about everything. You don’t have to know it all on day one. Knowing what to expect at those first vet visits gives you a place to start, and your veterinarian can help you make the right choices as your kitten grows.
Soon enough, the tiny kitten who needed you for everything will be a confident, curious cat, and you’ll know you gave them a healthy start.
FAQs about kitten vaccinations
What shots do kittens need and at what age?
Kittens usually start FVRCP at 6 to 8 weeks old, then receive boosters every 3 to 4 weeks until at least 16 weeks of age. Rabies is typically given around 12 to 16 weeks, depending on local law and the vaccine label. FeLV vaccination is recommended for all kittens through 1 year of age, then continued based on lifestyle and exposure risk.
When do kittens get their first shots?
Kittens typically get their first vaccine, the FVRCP, at 6 to 8 weeks old. Kittens adopted from a shelter may have already received their first round.
How many vaccinations do kittens need?
Most kittens receive 3 to 4 FVRCP vaccines, 2 FeLV vaccines, and 1 rabies vaccine during the initial kitten series. The exact number depends on when the kitten starts vaccines, prior records, health status, and local rabies requirements.
What is the FVRCP vaccine for kittens?
FVRCP stands for feline viral rhinotracheitis, calicivirus, and panleukopenia. It's a combination vaccine that protects against 3 serious diseases in one shot. It's considered the most important core vaccine for kittens and adult cats alike.
Can my kitten go outside before all their shots?
It's best to keep your kitten indoors and away from unvaccinated cats until they've completed their full vaccine series, usually around 16 weeks. Outdoor exposure before that point increases their risk of contracting serious, preventable diseases.
Are there risks to vaccinating kittens?
Vaccines are very safe. Mild side effects like temporary tiredness, soreness, or a slight fever are common and resolve quickly. Serious reactions are rare.
Do I need to vaccinate my kitten if I adopted them from a shelter?
Shelters typically start the vaccine series, but your kitten may still need additional doses to complete the schedule. Ask the shelter for your kitten's vaccination records and share them with your vet so they can pick up where the shelter left off.
How long do kitten vaccines last?
The initial kitten series provides protection for about a year. After the 1-year booster, FVRCP protection lasts about 3 years. Rabies booster timing depends on the vaccine type and state law. Your vet will set a schedule based on your cat's needs.
What happens if I miss a vaccine appointment?
Call your veterinarian and get back on the schedule. If the delay is short, your vet may continue the series. If the gap is long, your kitten may need additional doses to make sure the final vaccine is given at the right age and interval.
What is the 3/2/1 rule for cat vaccines?
The 3-2-1 rule helps cat owners know when a vaccine-site lump needs a veterinary exam. Call your vet if a lump is still there 3 months after vaccination, is larger than 2 centimeters, or is getting bigger 1 month after the shot. Most small vaccine-site bumps are harmless and fade on their own, but this rule helps catch rare problems early.
