Cat Vaccination Schedule: At a Glance
Vaccination protects your cat from serious, often fatal diseases. The schedule depends on age, lifestyle, and risk factors.
Kitten Vaccination Schedule
Vaccine
| Vaccine | Type | Protects Against | Kitten Schedule | Adult Booster | Who Needs It |
|---|---|---|---|---|---|
| FVRCP (Core) | Core | Feline Viral Rhinotracheitis, Calicivirus, Panleukopenia | 3 doses: 6-8, 10-12, 14-16 wks | Every 1-3 years | ALL cats — indoor and outdoor |
| Rabies (Core) | Core | Rabies virus (fatal, zoonotic) | Single dose at 12-16 wks | Every 1-3 years (by law) | ALL cats — required by law in most areas |
| FeLV | Non-Core | Feline Leukemia Virus | 2 doses: 10-12, 14-16 wks | Annually if at risk | Outdoor cats, multi-cat homes, cats exposed to FeLV+ cats |
| FIV | Non-Core | Feline Immunodeficiency Virus | 2-3 doses starting at 8 wks | Annually if at risk | Outdoor cats, cats in FIV+ households |
| Bordetella | Non-Core | Bordetella bronchiseptica | 2 doses: 8, 12 wks | Annually if at risk | Shelter cats, boarding, multi-cat environments |
Vaccination Best Practices
| Follow vet-recommended schedule — don't skip or delay | |
| Keep vaccination records — you'll need them for boarding, travel, emergencies | |
| Discuss lifestyle with vet — indoor-only cats may need fewer non-core vaccines | |
| Report any vaccine reactions (lethargy, swelling, vomiting) to vet immediately | |
| Even indoor cats need core vaccines — viruses can enter on shoes/clothing | |
| Skip vaccines because cat is 'indoor-only' — core vaccines are still essential | |
| Over-vaccinate — follow evidence-based schedules, not 'more is better' | |
| Assume one vaccine series lasts a lifetime — boosters are necessary |
Even strictly indoor cats need core vaccines (FVRCP and Rabies). Viruses like panleukopenia can enter your home on shoes, clothing, or other pets. Rabies vaccination is legally required in most jurisdictions — regardless of indoor/outdoor status.
Vaccine-associated sarcoma (VAS) is a rare but serious risk in cats (1 in 10,000). Discuss injection-site selection with your vet — vaccines are now given in specific locations (legs) to allow for easier treatment if VAS occurs.
Cat Vaccination Schedule: What Cats Need and When
Vaccines are one of the most important investments you can make in your cat's long-term health. They prevent fatal diseases that were once common killers of cats and kittens. This guide walks through the core vaccines every cat needs, optional vaccines based on lifestyle, and exactly when to get them.
💊 Core vs. Non-Core Vaccines
✅ Core (All Cats Need)
- FVRCP — Feline Viral Rhinotracheitis, Calicivirus, Panleukopenia (distemper)
- Rabies — Required by law in most US states
📋 Non-Core (Based on Risk)
- FeLV — Feline Leukemia (outdoor or multi-cat households)
- FIV — Feline Immunodeficiency Virus (outdoor cats)
- Bordetella — Cats in shelters or boarding
- Chlamydophila — Multi-cat environments
Kitten Vaccination Schedule
Kittens receive a series of vaccines starting at 6–8 weeks of age. The series is necessary because maternal antibodies from the mother's milk can interfere with the vaccine's effectiveness — multiple doses ensure protection once maternal immunity wanes.
| Age | Vaccines | Notes |
|---|---|---|
| 6–8 weeks | FVRCP (first dose) | Usually done by breeder or shelter |
| 10–12 weeks | FVRCP (second dose), FeLV (first dose if indicated) | First vet visit if just adopted |
| 14–16 weeks | FVRCP (third/final), Rabies (first), FeLV (second if indicated) | Rabies required by most state laws |
| 6 months | Spay/neuter (also a great health milestone) | Discuss timing with your vet |
Adult Cat Vaccination Schedule
| Vaccine | 1 Year After Kitten Series | Ongoing |
|---|---|---|
| FVRCP | Booster | Every 1–3 years (vet's discretion based on lifestyle) |
| Rabies | Booster | Every 1 year (1-year vaccine) or every 3 years (3-year vaccine) |
| FeLV | Booster if initially vaccinated | Annually for outdoor/at-risk cats |
Understanding Feline Distemper (Panleukopenia)
Despite the name FVRCP being a mouthful, panleukopenia is one of the most important vaccines. Feline panleukopenia virus is extremely hardy — it can survive on surfaces for years and is resistant to many disinfectants. Unvaccinated cats have an 80–90% mortality rate. The good news: the FVRCP vaccine is highly effective and provides long-lasting immunity.
Feline Leukemia Virus (FeLV): Who Needs It?
- Recommend FeLV vaccine: Outdoor cats, cats in multi-cat households with outdoor access, cats in shelters, kittens (all kittens under AAFP guidelines)
- Discuss with vet: Indoor-only cats with no exposure risk
- FeLV is contagious between cats through saliva, mutual grooming, and shared bowls — not through the environment
Vaccine Side Effects: What's Normal vs. Concerning
✅ Normal (24–48 hrs)
- Mild lethargy
- Reduced appetite
- Soreness at injection site
- Low-grade fever
🚨 Seek Vet Care
- Facial swelling or hives
- Vomiting or diarrhea
- Difficulty breathing
- Collapse or extreme lethargy
- Lump at injection site persisting >3 weeks (possible vaccine-associated sarcoma)
