Exact timing varies by clinic, vaccine brand, and local law — your vet sets the final plan.
Core vs non-core vaccines
- Core (all cats): FVRCP and rabies — protect against severe, common, or legally required diseases.
- FeLV (feline leukemia): recommended for all kittens; essential for cats that go outdoors or live with FeLV-positive cats.
- Other non-core: Bordetella, Chlamydia, FIV — only if your vet judges the risk warrants it.
Why kittens need a series
Newborn kittens get temporary immunity from their mother's milk, but it fades at an unpredictable age and can block a vaccine from "taking." Giving FVRCP every few weeks until ~16–20 weeks ensures protection kicks in as the maternal antibodies wear off. Until the series is finished, keep your kitten away from unvaccinated animals and high-risk areas.
Frequently asked questions
How much do kitten vaccinations cost?
The full kitten series often totals about $100–$300, depending on your area and which non-core vaccines are included. Low-cost clinics can be cheaper.
Are there side effects?
Most kittens are fine; some are a little tired or sore for a day. Call your vet if you see facial swelling, vomiting, or trouble breathing — rare reactions need prompt care.
What if my kitten missed a booster?
Don't panic — call your vet. Depending on the gap, they may continue the series or restart it. Staying roughly on schedule matters more than perfect dates.
