Kittens need several vaccinations during their first year to protect them against a variety of serious diseases. After that, they’ll need annual boosters.

6 to 8 weeks

  • Rhinotracheitis, Calcivirus, Panleukopenia, Chlamydia

10 to 12 weeks

Although not a vaccination, spaying or neutering can help protect your cat from a variety of health problems.


Your cat will need boosters on the core vaccines one year following the initial kitten vaccines. After that booster, these vaccines are generally boosted every one to three years, based on the specific vaccine used and the lifestyle of the cat.
