Kittens need vaccinations to protect them from infectious diseases once they no longer have their mothers immunity. Generally, there are two types of kitten shots: core vaccines and non-core vaccines. Core vaccines are essential shots required for all kittens and mature cats to defend against prevalent and/or harmful diseases. Non-core vaccines are optional vaccines for kittens and are recommended in certain areas for cats with certain lifestyles.

The core vaccines that all kittens should receive are:

• Feline rhinotracheitis
• Feline calicivirus
• Feline panleukopenia (FVRCP)
• Rabies

The first three are included in a combination vaccine given every three to four weeks until the kitten reaches 16 weeks of age. Rabies vaccine is usually given once at 12-16 weeks of age.

Non-core vaccines are not administered to every kitten, but are recommended in certain areas for cats with certain lifestyles. For example, the feline leukemia virus (FeLV) vaccine is recommended for all kittens that are exposed to outdoor cats.

Kittens should get their first vaccinations at 6-8 weeks of age and are repeated every 3-4 weeks until the kitten is 16-20 weeks old. Immunizations must be given as a series of injections at prescribed intervals, so it is essential that you are on time for your kitten’s scheduled vaccinations. Kittens need vaccine boosters every one to three years (depending on the type and individual circumstances) to maintain active, long-lasting immunity.

It is important to consult with your veterinarian to determine which vaccines are best for your kitten based on their lifestyle and risk factors.
