Vaccination is one of the most effective tools for protecting a kitten during the vulnerable period after maternal antibody protection fades. The right schedule depends on the kitten's age, prior vaccination history, lifestyle, and your veterinarian's guidance — not a single universal chart.

Core vaccines for kittens

Core vaccines are recommended for virtually all cats regardless of lifestyle. The FVRCP combination protects against feline viral rhinotracheitis (herpesvirus), calicivirus, and panleukopenia. Rabies vaccination is required by law in most jurisdictions and is considered core.

Kittens typically receive a series of FVRCP vaccines beginning around six to eight weeks of age, with boosters every three to four weeks until approximately sixteen weeks. A single rabies vaccine is given at an appropriate age per label and local law. Boosters follow at one year and then on a schedule determined by the veterinarian and product used.

What the breeder has already done

Most reputable breeders begin the vaccine series before placement. Ask for the exact product name, lot number, date administered, and the veterinarian or breeder who gave it. This information is needed to continue the series correctly and avoid either gaps or unnecessary over-vaccination.

Do not assume a kitten is fully protected because it received one or two vaccines. The series must be completed for reliable immunity.

Non-core vaccines

Non-core vaccines are given based on individual risk. Feline leukemia virus vaccine is often recommended for kittens with outdoor access or exposure to unknown cats. Feline immunodeficiency virus, Chlamydophila, Bordetella, and other vaccines may be appropriate in specific situations.

Discuss lifestyle, household composition, and risk factors with the veterinarian to determine which non-core vaccines are appropriate.

Vaccine-associated sarcoma awareness

Feline injection-site sarcoma is a rare but serious tumor that can develop at vaccine injection sites. To aid monitoring, vaccines are typically given in specific low-limb locations in cats. Know where vaccines were given and monitor for any persistent lump. A lump that grows, persists beyond four weeks, or is larger than two centimeters should be evaluated promptly.

Titer testing

Antibody titer tests can measure immune response to certain vaccines and may be used to help determine whether a booster is needed. They are not a replacement for rabies vaccination in jurisdictions that require it, and interpretation requires veterinary guidance. Some owners use titers to avoid unnecessary revaccination in adult cats.

Frequently asked questions

Can I vaccinate my kitten at home?

Some vaccines are available over the counter, but veterinary administration allows for health assessment, proper documentation, and management of rare adverse reactions. Rabies vaccines given outside a licensed veterinary setting may not satisfy legal requirements.

What if my kitten has a reaction after vaccination?

Mild lethargy or soreness for a day or two is common. Facial swelling, vomiting, difficulty breathing, collapse, or severe lethargy shortly after vaccination are emergencies requiring immediate veterinary care.

Do indoor-only Maine Coons need all the same vaccines?

Core vaccines are still recommended for indoor cats. Discuss non-core vaccines based on actual risk factors with the veterinarian.

A practical next step

Bring the kitten's complete vaccination record to the first veterinary appointment and ask the veterinarian to map out the remaining series and booster schedule. File the records somewhere you can find them. Contact Dashing Coons for questions about our kitten health documentation.
