Kittens need their first vaccines at 6-8 weeks old, with boosters every 3-4 weeks until they reach 16 weeks of age. The 2020 AAHA/AAFP Feline Vaccination Guidelines¹ recommend core vaccines (FVRCP and rabies) for all cats, regardless of whether they live indoors or outdoors. Spot Pet Insurance plans offer optional preventive care add-ons for an additional cost, that can help cover vaccination costs as part of your cat’s wellness routine.
Kitten Vaccination Schedule
Follow this schedule based on the AAHA/AAFP guidelines¹ to ensure your kitten develops full immunity:
Age | Vaccines | Notes |
|---|---|---|
6-8 weeks | FVRCP (1st dose) | Can start as early as 6 weeks |
10-12 weeks | FVRCP (2nd dose), FeLV (1st dose) | FeLV recommended for all kittens |
14-16 weeks | FVRCP (3rd dose), FeLV (2nd dose), Rabies | Complete initial series |
1 year | FVRCP booster, Rabies booster | Annual boosters after initial series |
Adult (ongoing) | FVRCP every 3 years, Rabies per state law | Typically every 1-3 years for rabies |
The timing between doses matters. According to PetMD³, "If vaccines are not given in the appropriate time frame, they will likely be ineffective."
What Vaccines Do Cats Need?
Cat vaccines divide into two categories: core vaccines (essential for all cats) and non-core vaccines (recommended based on lifestyle).
Core Vaccines for All Cats
FVRCP (Feline Viral Rhinotracheitis, Calicivirus, Panleukopenia)
This combination vaccine protects against three serious diseases:
Feline panleukopenia (FPV): Also called feline distemper, this highly contagious virus attacks rapidly dividing cells. The WSAVA⁴ notes it can be fatal, particularly in kittens.
Feline herpesvirus (FHV-1): Causes upper respiratory infections with symptoms including sneezing, nasal discharge, and eye problems. Can become a lifelong latent infection.
Feline calicivirus (FCV): Another respiratory virus that can cause oral ulcers and pneumonia. Multiple strains exist, though vaccines protect against the most common.
Rabies
Rabies vaccination is required by law in most states because this fatal viral disease can spread to humans. There is no cure for rabies in any species. Your kitten should receive their first rabies vaccine at 12-16 weeks of age, with a booster one year later.
Non-Core Vaccines
Feline Leukemia Virus (FeLV)
The AAHA/AAFP guidelines¹ consider FeLV a core vaccine for kittens under 1 year old. After age 1, it becomes non-core—recommended only for cats that go outdoors or live with FeLV-positive cats.
FeLV is transmitted through close contact (mutual grooming, shared food bowls) or bite wounds. It can cause:
Immune system suppression
Anemia
Lymphoma and other cancers
Other Non-Core Vaccines
Chlamydia felis: Recommended for multi-cat households with known infection
Bordetella bronchiseptica: Sometimes recommended for cats in shelters or catteries
Feline immunodeficiency virus (FIV): Less commonly recommended due to variable effectiveness
Discuss your cat's lifestyle with your veterinarian to determine which non-core vaccines are appropriate.
How Much Do Cat Vaccines Cost?
Vaccination costs vary by location and veterinary practice. According to CareCredit² cost data:
Vaccine | Average Cost |
|---|---|
FVRCP | $32² |
Rabies | $30² |
Feline Leukemia (FeLV) | $42² |
Bordetella | $36² |
Additional first-year costs:
Initial veterinary exam: $53-124² (cats)
Fecal exam: $36²
Deworming: $28²
Low-cost vaccination clinics and shelters may offer reduced rates. Many adoption fees include initial vaccinations.
Do Indoor Cats Need Vaccines?
Yes. Even cats that never go outside should receive core vaccines. Here's why:
Viruses can enter your home through:
Your clothing and shoes
Other pets that go outdoors
Open windows (airborne transmission)
Escaped cats returning home with exposure
Legal requirements: Rabies vaccination is legally required in most states regardless of indoor/outdoor status. If your unvaccinated cat bites someone—even accidentally—there can be serious legal consequences.
Boarding and emergencies: Most boarding facilities, groomers, and veterinary hospitals require proof of current vaccinations.
Does Pet Insurance Cover Vaccinations?
Standard pet insurance plans typically don't cover routine vaccinations because they're considered preventive care rather than treatment for illness or injury.
However, Spot Pet Insurance offers preventive care add-ons for an extra cost that can help cover vaccination costs:
Gold Preventive Care Add-On helps cover:
Vaccinations
Annual wellness exams
Spay/neuter procedures
Dental cleaning
Fecal and heartworm tests
Platinum Preventive Care Add-On offers higher reimbursement limits for the same services.
Learn more about pet insurance with wellness coverage to see if a preventive care add-on fits your needs.
What Pet Insurance Does Cover
While vaccinations fall under preventive care, Spot's accident and illness coverage can help with:
Vaccine reactions: If your cat has a severe allergic reaction requiring emergency treatment
Illnesses prevented by vaccines: If your cat contracts a covered illness before vaccination
Diagnostic tests related to vaccine-preventable diseases
Vaccine Side Effects in Cats
Most cats tolerate vaccines well, but minor side effects can occur. According to veterinary guidance, watch for:
Mild (common, resolve within 24-48 hours):
Tiredness and reduced activity
Mild fever
Soreness or small lump at injection site
Moderate (contact your vet):
Vomiting
Diarrhea
Loss of appetite lasting more than 24 hours
Severe (seek emergency care immediately):
Facial swelling
Hives or skin reactions
Difficulty breathing
Collapse or shock
If you notice any concerning symptoms after vaccination, contact your veterinarian promptly.
Adult Cat Vaccination Schedule
After completing the kitten series, adult cats need ongoing boosters to maintain immunity:
Vaccine | Booster Frequency | Notes |
|---|---|---|
FVRCP | Every 3 years | After 1-year booster |
Rabies | Every 1-3 years | Depends on vaccine type and state law |
FeLV | Annually (if at risk) | For outdoor cats or those exposed to FeLV+ cats |
The WSAVA 2024 guidelines⁴ note that FVRCP every 3 years provides sufficient protection for healthy adult cats. Your veterinarian may recommend different intervals based on your cat’s health status and risk factors.
When to Start Vaccinations After Adoption
If you're adopting a kitten or adult cat:
From a shelter or rescue: Most shelters vaccinate cats before adoption. Ask for vaccination records and confirm which vaccines were given and when the next doses are due.
From a breeder: Request documentation of vaccinations. Reputable breeders start the vaccination series before kittens go to new homes.
Stray or unknown history: Schedule a veterinary exam within 48 hours. Your vet will assess the cat's health and recommend a vaccination catch-up schedule.
Regardless of where your cat comes from, schedule a vet visit within the first week to review vaccination status and establish a care plan.
Preparing for Your Cat's Vaccination Appointment
Make vaccination visits less stressful:
Carrier training: Leave the carrier out with treats inside so your cat associates it with positive experiences
Timing: Schedule appointments during quieter clinic hours if your cat is anxious
History: Bring any previous vaccination records
Questions: Ask about which vaccines are recommended based on your cat's lifestyle
After vaccination, keep your kitten indoors and monitor for side effects. Kittens should stay inside until 7-10 days after their final 16-week vaccines to ensure full protection.
