Which vaccines does an indoor cat need?

Most indoor cats need the core vaccines: rabies, which Virginia requires for every cat, and the combined vaccine for feline distemper and two common respiratory viruses. Other vaccines depend on lifestyle. A cat that never goes outside and lives with no outdoor cats usually does not need the feline leukemia vaccine after kittenhood; a cat that goes out, boards or meets new cats may.

Indoor cats still meet germs. Viruses travel in on shoes and clothing, bats and mice sometimes get into homes, and an indoor cat can slip out a door. The core vaccines are chosen because the diseases they prevent are serious and the risk is never zero.

Core and lifestyle vaccines

CoreRabies

Required for every cat in Virginia. Given as a kitten, at one year, then on a one- or three-year schedule.

CoreDistemper and respiratory viruses

One combined vaccine, boosted as a kitten, at one year, then every three years.

LifestyleFeline leukemia

Recommended for all kittens, then for cats that go outside or live with cats that do.

How we decide for your cat

01.Ask

We ask where your cat goes and who it meets.

02.Check

We review past records and any reactions.

03.Explain

You get a short list with a reason beside each vaccine.

04.Remind

We text you before each booster is due.

Reactions to vaccines are uncommon and usually mild: a quiet evening or a tender patch where the needle went in. Let us know if your cat has had a reaction in the past. We can space vaccines out, change the site or skip a lifestyle vaccine that is not needed.

The right vaccine list depends on the cat in front of us, not a one-size chart on the wall.

Questions owners ask

Does an indoor cat really need rabies?
Yes. Virginia requires it, and bats do get into homes. It is one of the two core vaccines for every cat.
How often are boosters given?
After kittenhood and the one-year booster, most core boosters move to a three-year interval. Rabies may be yearly or every three years depending on the vaccine used.
My cat had a reaction last time. What now?
Let us know ahead of the appointment. We may space vaccines out, pre-treat or change which vaccines are given.
Can my senior cat stop having vaccines?
Not entirely, but we tailor the list as cats age and their lifestyle changes.
