What vaccinations does my cat need?

Updated 2026-07-16 · Not a substitute for professional veterinary care

Good to know

Short answer

Kittens need a series of core vaccines starting around 6 to 8 weeks, boostered every few weeks until about 16 weeks, then a booster at a year. Adult cats need periodic boosters, usually every 1 to 3 years depending on the vaccine and your vet. The core vaccines protect against panleukopenia, feline herpesvirus, calicivirus, and rabies.

The core vaccines

A typical schedule

Your vet tailors this to your cat's age, health, and whether it goes outside. Indoor-only cats still need core protection.

Why it matters even for indoor cats

The diseases these vaccines prevent are widespread, and some, like panleukopenia, are often fatal. Viruses can enter on shoes and clothing, so indoor cats are not fully safe without core vaccines. Keeping a simple record of dates and due boosters helps you and your vet stay on track.

When in doubt, call a vet. This guide is general information for cat owners. It is not veterinary advice, and it is not a substitute for professional veterinary care, diagnosis, or treatment. If your cat is in distress, contact a veterinarian or your nearest emergency clinic straight away.

Notice the quiet changes early

Hirra is a free, private cat-health app. A five-second daily check-in learns your cat's normal and flags the drifts in weight, thirst, appetite, and litter that owners miss, and its free "Is This Safe?" checker looks up foods in seconds. It never diagnoses. It helps you notice, and points you to a vet sooner.

Common questions

Do indoor cats need vaccines?

Yes. Core vaccines are recommended for all cats because the diseases are common and can enter the home on clothing and shoes. Your vet may adjust non-core vaccines for an indoor lifestyle.

How often do adult cats need boosters?

Usually every 1 to 3 years depending on the specific vaccine, your local laws, and your cat's lifestyle. Your vet will set the right interval.

How do I keep track of vaccine dates?

Note each vaccine and its due date. Hirra stores your cat's profile and sends vaccination reminders so a booster is less likely to slip.
