Cat Vaccination Guide — Schedule, Types & Costs

Kitten Schedule Kittens need multiple doses because maternal antibodies gradually decline.

1. 1st dose (around 8 weeks): Often administered by the breeder
2. 2nd dose (around 12 weeks): Given at the veterinary clinic after adoption
3. 3rd dose (around 16 weeks): A final dose for solid immunity (at veterinary discretion)

Important: Until vaccination is complete, minimize contact with other cats.

Adult Cat Schedule - **Booster 1 year** after completing the kitten series - Subsequent boosters every **1–3 years**. WSAVA guidelines recommend 3-year intervals for core vaccines - Non-core vaccines (e.g., feline leukemia) are often recommended **annually** - Antibody titer testing to assess vaccination needs is also becoming more common

Why Indoor-Only Cats Still Need Vaccines

Thinking "my cat never goes outside" can be dangerous. Consider these risks:

• Owners tracking in pathogens: Viruses can hitchhike on shoes and clothing
• Escape during disasters: Windows and doors can't be guaranteed escape-proof at all times
• Veterinary clinic exposure: Contact with infected cats in the waiting room is possible
• Adding a new cat: The newcomer may carry pathogens

At minimum, the 3-way combination vaccine is recommended even for fully indoor cats.

Estimated Costs

• 3-way combination: 3,000–6,000 yen/dose
• 4-way combination: 5,000–7,000 yen/dose
• 5-way combination: 6,000–8,000 yen/dose
• Antibody titer test: 5,000–10,000 yen

The kitten series (2–3 doses) costs roughly 6,000–24,000 yen total, while annual adult costs run approximately 3,000–8,000 yen.

Side Effects and Precautions

The following reactions may occur after vaccination:

• Mild reactions (resolve in 1–2 days): Swelling at the injection site, slight fever, temporary decrease in appetite or activity
• Severe reactions (seek immediate care): Facial swelling, vomiting, difficulty breathing, lethargy
• Feline Injection-Site Sarcoma (FISS): Very rare, but a malignant tumor can develop at the injection site. Precautions include rotating injection sites and using the hind legs

Post-vaccination guidelines: - Wait 30 minutes to 1 hour at or near the veterinary clinic - Avoid bathing and vigorous play on vaccination day - Keep activity light for 2–3 days and monitor appetite, energy, and elimination - If a lump persists at the injection site for more than 3 months, schedule a follow-up visit
