Kitten Vaccination Schedule: Core Shots, Timing, and What First-Time Owners Need to Know
- Most kittens start FVRCP vaccines at 6-8 weeks of age, then repeat every 3-4 weeks until at least 16 weeks old.
- Rabies is a core vaccine and is usually given at or after 12 weeks, based on state law and product label.
- FeLV is considered core for kittens under 1 year old, with a first dose commonly given at 8-12 weeks and a booster 3-4 weeks later.
- A kitten is not fully protected after one visit. Protection builds over the series, and maternal antibodies can interfere early on.
- Expect vaccine-only clinic costs to run about $60-$150 for the basic kitten series, while full-service first-year preventive visits often total about $250-$600 depending on exam fees, testing, and region.
Getting Started
Vaccines are one of the first big health decisions you will make for a new kitten. The goal is not to give every possible shot at once. It is to build protection at the right ages, when maternal antibodies are fading and your kitten can respond well to vaccination.
For most kittens in the United States, the core plan includes FVRCP for panleukopenia, herpesvirus, and calicivirus, plus rabies. FeLV is also considered core for kittens under 1 year old because young cats are more vulnerable if they are exposed. Your vet may adjust timing based on age at adoption, shelter history, indoor-only plans, local rabies rules, and whether your kitten lives with or may meet other cats.
The most important thing for first-time pet parents to know is that one vaccine visit does not finish the job. Kittens usually need a series every 3 to 4 weeks until at least 16 weeks old, and sometimes a later booster depending on the product and your vet's protocol. If your kitten came from a rescue, breeder, or foster home, bring every record you have so your vet can avoid unnecessary repeats and keep the schedule on track.
Your New Pet Checklist
First vet visit and records
- ☐ Schedule your kitten’s first wellness exam within a few days of coming home
Exam fees vary by region and clinic type.
- ☐ Bring adoption, breeder, or shelter vaccine paperwork
This helps your vet decide what counts and what needs repeating.
- ☐ Ask for a written vaccine plan with due dates through 16 weeks and the 1-year booster
A printed schedule reduces missed boosters.
Core preventive care
- ☐ FVRCP vaccine series
Often 3-4 doses total depending on starting age and prior history.
- ☐ Rabies vaccine
Usually given at or after 12 weeks, depending on state law and product.
- ☐ FeLV vaccine series
Commonly 2 doses for kittens under 1 year old.
- ☐ FeLV/FIV test if status is unknown
Especially helpful for adopted kittens and multicat homes.
- ☐ Fecal parasite test and deworming plan
Very common in kittens, even when they look healthy.
Home setup for a safer vaccine period
- ☐ Keep your kitten indoors until your vet says the vaccine series is far enough along
Avoid contact with unknown cats and shared outdoor spaces.
- ☐ Use a secure carrier for every visit
A hard-sided or sturdy soft-sided carrier helps reduce stress and escape risk.
- ☐ Set up a separate room if you have other cats until testing and early vaccines are done
Useful for disease control and gradual introductions.
Planning ahead
- ☐ Budget for the 1-year booster visit now
May include exam plus booster vaccines.
- ☐ Ask whether a vaccine clinic or full-service practice fits your kitten’s needs
Vaccine clinics can lower cost range, but they may not replace a full exam-based relationship.
What shots are considered core for kittens?
For kittens, the usual core vaccines are FVRCP and rabies. FVRCP protects against feline panleukopenia, feline herpesvirus-1, and feline calicivirus. These infections can be severe, especially in young kittens, and panleukopenia can be life-threatening.
Current feline vaccination guidance also treats FeLV as core for kittens under 1 year old. That does not mean every adult indoor cat needs ongoing FeLV boosters forever. It means kittens deserve early protection while their future lifestyle is still developing and because young cats are at higher risk if exposed.
Typical kitten vaccine timeline
- 6-8 weeks: First FVRCP
- 9-12 weeks: Repeat FVRCP every 3-4 weeks; many kittens also start FeLV during this window
- 12 weeks or older: Rabies, depending on state law, product label, and your vet's plan
- 3-4 weeks after first FeLV: FeLV booster
- Until at least 16 weeks old: Continue FVRCP every 3-4 weeks until the final kitten dose is given at 16 weeks or later
- Around 1 year after the kitten series: Booster visit for core vaccines based on product and your vet's recommendations
Some practices also give an additional booster around 6 months for certain protocols or risk situations. Your vet will tailor the exact plan to your kitten's age, prior records, and exposure risk.
Why kittens need multiple vaccine visits
Kittens get temporary antibodies from their mother, mainly through early nursing. Those antibodies help protect them at first, but they can also block vaccines from working well. Because no one can predict the exact day those antibodies fade, vets use a series of vaccines spaced every 3 to 4 weeks.
That schedule increases the chance that at least one dose lands when maternal antibodies are low enough for the vaccine to create strong protection. This is why a kitten who had one or two shots before adoption may still need more doses.
What to expect after vaccination
Most kittens do well after vaccines. Mild tiredness, a small decrease in appetite, or brief soreness for a day or two can happen. These signs usually improve within 24 to 48 hours.
Call your vet promptly if your kitten has vomiting, diarrhea, facial swelling, hives, trouble breathing, collapse, or severe lethargy after vaccination. Also let your vet know if you notice a lump at an injection site that grows, stays present for weeks, or seems painful.
Indoor kittens still need vaccines
Indoor-only is safer, but it is not zero risk. Rabies remains important because bats and other wildlife can enter homes, and rabies laws usually apply regardless of lifestyle. FeLV is recommended in kittens because future lifestyle can change, accidental escapes happen, and some kittens eventually join multicat homes.
If your kitten will remain strictly indoors as an adult with no contact with cats of unknown status, your vet may later recommend fewer non-core boosters. The kitten series is still the foundation.
Vaccine clinic vs full-service practice
A vaccine clinic can be a good conservative care option for straightforward preventive care. It may lower the cost range for FVRCP, rabies, and FeLV. Still, many first-time pet parents benefit from establishing care with a full-service clinic, especially if the kitten has diarrhea, sneezing, poor weight gain, parasites, or an uncertain medical history.
You do not have to choose one forever. Some families use a full-service clinic for exams and illness care, then use community vaccine clinics for selected boosters when appropriate. Ask your vet what makes sense for your kitten.

Questions to Ask Your Vet
Bring these questions to your vet appointment to get the most out of your visit.
- Which vaccines does my kitten still need based on these records?
- What exact dates should I book the next FVRCP, rabies, and FeLV visits?
- Does my kitten need FeLV testing before vaccination?
- Is my kitten healthy enough for vaccines today, or should we delay because of sneezing, diarrhea, or fever?
- When will my kitten be protected enough to meet other cats or go into shared spaces?
- Which vaccines are core for my kitten, and which are lifestyle-based?
- What mild vaccine reactions are normal, and which signs mean I should call right away?
- What should I budget for the rest of the kitten vaccine series and the 1-year booster?
Frequently Asked Questions
When do kittens get their first shots?
Most kittens start FVRCP at 6 to 8 weeks of age. After that, boosters are usually given every 3 to 4 weeks until at least 16 weeks old.
What does FVRCP protect against?
FVRCP covers feline viral rhinotracheitis or herpesvirus-1, calicivirus, and panleukopenia. These are major infectious diseases in young cats.
Does an indoor kitten need rabies and FeLV vaccines?
Rabies is still important for indoor kittens because of legal requirements and rare wildlife exposure. FeLV is considered core for kittens under 1 year old, even if they are expected to live indoors.
Why does my kitten need so many boosters?
Maternal antibodies can block early vaccine response. Repeating vaccines every 3 to 4 weeks helps make sure your kitten develops protection once those antibodies fade.
Can my kitten go outside after the first vaccine?
Usually no. It is safer to wait until your vet says the vaccine series is far enough along. One early dose does not provide full protection.
How much do kitten vaccines usually cost?
Vaccine-only clinics may charge roughly $20 to $50 per vaccine, while full-service visits often add exam fees and testing. Many pet parents spend about $250 to $600 on first-year vaccine-related preventive care.
