Kitten Vaccine Schedule: Complete Timeline for New Cat Owners (2026)

A new kitten feels like a blur of firsts - first vet visit, first night home, first time you realize you have no idea what “FVRCP” stands for on the vaccine sheet. Kitten vaccines follow a similar logic to puppies: a series of shots spaced out over weeks, because a kitten’s immune system needs time to respond fully, and early doses can be blocked by antibodies passed down from their mother.

Here’s the timeline vets typically follow.

6 to 8 weeks: the first round

This is usually the FVRCP combination vaccine - covering feline viral rhinotracheitis, calicivirus, and panleukopenia. If your kitten came from a shelter or breeder, ask for the vaccine paperwork; this first round may already be checked off.

10 to 12 weeks: the second round

A repeat of the FVRCP series. This is often when vets discuss FeLV (feline leukemia) testing and vaccination too, especially relevant if your kitten will ever go outside or live with other cats.

14 to 16 weeks: the final kitten round and rabies

This finishes the core series and typically includes the rabies vaccine, which is legally required in most areas regardless of whether your cat goes outside. Many new owners assume an indoor-only cat can skip it - worth checking your local rules rather than assuming.

12 months: the first booster

About a year later, most cats get a booster to reinforce the kitten series. After that, boosters usually shift to every 1-3 years depending on the vaccine and your vet’s recommendation.

What if you fall behind schedule?

A missed appointment isn’t a crisis - it usually just means picking the series back up rather than starting completely over. If a longer gap has passed, your vet may recommend a titer check or restarting the current stage, but it’s rarely as dramatic as it feels in the moment.

This is exactly why PawCare AI’s vaccine tracking exists - log each shot as it happens, and the app keeps track of what’s due next, so you’re not trying to recall dates from memory months later.

The bottom line

A kitten’s vaccine schedule mirrors a puppy’s fairly closely - three rounds in the first few months, then a yearly rhythm after that. The one extra conversation worth having with your vet is indoor vs. outdoor lifestyle, since it changes which non-core vaccines actually make sense.
