Cat Vaccination Schedule: What Shots Your Cat Needs and When

Published June 5, 2026 · 7 min read

Cat vaccinations follow a similar logic to dog vaccinations but with a different set of diseases and different risk factors to consider. The biggest variable for cats is indoor versus outdoor access, which changes which non-core vaccines your vet will recommend and how aggressively they'll want to maintain them.

What follows is based on guidelines from the American Veterinary Medical Association and the American Association of Feline Practitioners. Your vet will adjust the schedule based on your cat's specific situation, but this gives you a working baseline.

Core vs. non-core vaccines

Core vaccines are recommended for every cat regardless of whether they go outside. They cover diseases that are widespread, severe, or pose a risk to humans. Non-core vaccines are given based on your cat's specific risk profile. An outdoor cat who encounters other cats, wildlife, or unvaccinated animals has a very different risk profile than one who never leaves the house.

Core vaccines

FVRCP is sometimes called the "distemper combo" for cats. Panleukopenia (feline distemper) is a severe and often fatal disease in kittens. Herpesvirus and calicivirus cause upper respiratory infections that are highly contagious between cats and can become chronic. All three are common enough that vaccination is considered essential regardless of lifestyle.

Common non-core vaccines

FeLV is worth discussing with your vet even if your cat is currently indoor-only. Situations change. Cats escape, foster cats arrive, or households merge. Many vets recommend vaccinating during the kitten series as a precaution and reassessing annually.

Kitten vaccination schedule

Kittens need a series of vaccines spaced several weeks apart. Maternal antibodies passed through the mother's milk gradually fade over the first few months, but they also interfere with vaccine effectiveness, which is why a single shot isn't enough. A typical kitten schedule:

Adult cat booster schedule

After the kitten series is complete, FVRCP is typically given every 1 to 3 years depending on the vaccine formulation and your vet's protocol. Rabies frequency is often set by local law. Non-core vaccines like FeLV are given annually for cats who remain at risk.

Indoor cats sometimes prompt owners to question whether boosters are necessary at all. Vets generally recommend maintaining them for two reasons: indoor status isn't guaranteed to last forever, and some diseases like panleukopenia can persist in the environment for months. A lapse of several years followed by any outside exposure is a real risk.

Indoor cats vs. outdoor cats

The distinction matters most for FeLV and FIV, which are spread through close contact with infected cats. An indoor-only cat with no exposure to other cats has a low risk. An outdoor cat who roams, fights, or shares food bowls with neighborhood cats has a meaningfully higher one.

If your cat has access to a screened porch, a catio, or goes outside on a leash, your vet will typically consider them at some outdoor risk and may recommend FeLV vaccination accordingly. The conversation is worth having explicitly at each annual visit as your cat's situation can change.

Keeping vaccination records

Cat vaccination records matter in the same situations as dog records: boarding, grooming, moving to a new area, or switching vets. Many boarding facilities and catteries require proof of current FVRCP and Rabies before accepting a cat.

Clinics typically track due dates internally, but those records don't follow your cat when you move or switch vets. Keeping your own record of each vaccine given, the date, and the next due date gives you a backup that stays with you regardless of where your cat receives care.
