What vaccinations should my cat receive?

Vaccinations are an important part of caring for your cat. Vaccines provide protection from some diseases such as enteritis (feline panleukopaenia) and cat flu (feline calicivirus and feline herpesvirus).

Cats who are vaccinated will either show no signs of illness or are less likely to become seriously ill from specific diseases.

Core and non-core vaccinations [1, 2]

Core vaccines are those that all unvaccinated cats and cats with an unknown vaccination history should receive to protect them against key diseases including enteritis (feline panleukopaenia, a parvovirus) and cat flu (feline calicivirus and feline herpesvirus). This vaccination combination is commonly known as the F3 vaccination.

Non-core vaccines are those that should only be given to cats in specific risk categories based on an individual risk/benefit assessment [2]. This assessment will take into account the geographical location, lifestyle, and risk of exposure to the infection of the individual cat. Examples of non-core vaccines include those for feline leukaemia virus (FeLV), feline immunodeficiency virus (FIV), Chlamydia felis and Bordetella bronchiseptica.

Please speak to your veterinarian for the most appropriate advice for your individual cat.

Kitten vaccinations [1, 2, 3]

The first core vaccination administered to kittens is from 6-8 weeks of age, then every 3–4 weeks until 16–20 weeks of age. The World Small Animal Veterinary Association (WSAVA) now recommends that a booster vaccine is given at then given at 6 months of age to ensure that a protective immune response develops in any cat that may not have responded to any of the first three vaccines [3]. It is important to follow this schedule to ensure the vaccines are effective.

Please speak to your veterinarian about what vaccinations are right for your kitten or if you are concerned about your kitten’s vaccination being overdue.

Adult cat vaccinations [1, 2, 3]

An adult cat who has received a primary vaccination course will require the core vaccination every 1-3 years, depending on the duration of immunity provided by the vaccine your veterinarian uses and the cat’s individual circumstances. Check with your veterinarian.

If you have a cat who is an adult but has not been vaccinated or whose vaccination history or status is unknown, they will need two doses of the core vaccination, 3–4 weeks apart. After this the cat should receive a vaccination every 1–3 years. If you’re introducing another cat with an unknown vaccination history to your household, if possible ensure vaccination with core vaccines at least a week before bringing the cat home to meet your other animals.

If you are considering breeding your cat, discuss your cat’s vaccination needs with your veterinarian and follow their recommendations before breeding.

Frequency of vaccinations for adult cats and boarding facility requirements

The frequency of feline booster vaccinations varies from 1-3 years depending on the vaccine, the disease, and the risk of disease exposure to the individual cat. In general, it is recommended by expert panels on feline vaccination that cats who stay at a boarding cattery require an annual vaccination schedule (or a booster vaccine before the cat goes into the boarding facility if the cat has not been vaccinated in the preceding year) as this can be a higher risk situation than a normal home environment [1, 2]. This is because boarding may be stressful for a cat and stress has immunosuppressive effects which may result in increased susceptibility to infection and disease and additionally there can be a higher risk of exposure to infectious disease.

For these reasons, it is still recommended that a cat should have a vaccination within 12 months of entering a boarding facility, and why almost all cat boarding facilities require cats to have received a vaccination booster within 12 months prior to admission to the facility.

It is best to speak to your vet about your cat’s individual needs. Your veterinarian will always do a health check before administering a vaccination to ensure your kitten or cat is healthy to be vaccinated. In addition, this provides an excellent opportunity for your veterinarian to fully examine your cat and discuss any health issues. This allows any health concerns that your cat may have to be addressed as early as possible, giving your cat the best chance possible to be healthy and comfortable.

The core vaccines used in cats are very safe with a very low incidence of adverse reactions; the benefits of protection from serious infectious disease significantly outweigh the risks of developing an adverse reaction. If you have any concerns about adverse vaccine reactions or the health of your cat, it is best to speak to your veterinarian.
