Kitten Vaccines: When to Start and Which Ones

Kittens should start their core vaccines at 6–8 weeks of age, with boosters every 2–4 weeks until they are 16 weeks or older. Vaccines help protect against common serious diseases such as feline panleukopenia and cat flu.

Core vaccine schedule

Age	Vaccine
6–8 weeks	First dose of core vaccine: feline panleukopenia + cat flu
Every 2–4 weeks	Boosters until 16 weeks of age or older
2–4 months	First rabies dose, then 1 booster 1 month later
6 months – 1 year	Core vaccine booster, as scheduled by your vet
Every year	Health check + rabies; your vet plans the next doses

Optional vaccines

Feline leukemia (FeLV) is recommended for cats under 1 year old or cats that go outdoors. A blood test is needed first. It is given as 2 doses, 3–4 weeks apart, and can start from 8 weeks of age. Your vet will advise based on your kitten's risk.

Before and after vaccination

Before the vaccine, your kitten should be healthy:

• No fever, not lethargic
• No diarrhea, no vomiting
• No sneezing, no runny nose
• Playful and eating normally

After the vaccine, your kitten may be a little sleepy or have a mild fever for 1–2 days. If you see facial swelling, difficulty breathing or vomiting, bring your kitten back to the vet right away.

The actual vaccine schedule depends on your vet's assessment.
