Good to knowShort 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.
Your vet tailors this to your cat's age, health, and whether it goes outside. Indoor-only cats still need core protection.
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.
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.
Free on the App StoreYes. 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.
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.
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.
