Vaccinating your cat is one of the most important things you can do to protect them from serious and potentially fatal diseases. Whether your cat is an indoor pet or spends time outdoors, vaccinations help strengthen their immune system and prevent the spread of contagious diseases.
This guide will explain why vaccinations are essential, what diseases they protect against, and when your cat should be vaccinated.
How Do Vaccinations Work?
Vaccines help prepare your cat’s immune system to fight off harmful diseases. They contain a safe version of a virus or bacteria (either weakened or inactive), which stimulates the immune system to develop protective antibodies. If your cat is ever exposed to the actual disease, their immune system is already equipped to fight it off, reducing the risk of severe illness.
Vaccinating your cat doesn’t just protect them – it also helps prevent outbreaks of contagious diseases in the wider feline population, including vulnerable kittens and elderly cats with weaker immune systems.
What Diseases Do Cat Vaccinations Protect Against?
In Australia, there are several highly contagious and potentially fatal diseases that cats should be vaccinated against.
Core Vaccinations (Essential for All Cats)
These core vaccines protect against life-threatening diseases that can affect all cats, regardless of lifestyle:
- Feline Enteritis (Feline Panleukopenia) – A highly contagious and often fatal disease that causes vomiting, diarrhoea, fever, and severe dehydration. It spreads through direct contact with infected cats or contaminated environments.
- Feline Calicivirus (Cat Flu) – Causes respiratory infections, mouth ulcers, and joint pain. It is highly contagious and spreads through sneezing, grooming, and shared food bowls.
- Feline Herpesvirus (Cat Flu) – Another common cause of upper respiratory infections, leading to sneezing, eye discharge, and long-term health issues.
Non-Core Vaccinations (Recommended Based on Lifestyle & Risk Factors)
These additional vaccines may be recommended based on a cat’s environment and risk of exposure:
- Feline Immunodeficiency Virus (FIV) – A virus that weakens the immune system, making cats more vulnerable to infections. It spreads through deep bite wounds, making outdoor and fighting cats at higher risk.
A vet can help determine which non-core vaccines are necessary based on your cat’s lifestyle and risk factors.
When Should Your Cat Be Vaccinated?
Kittens and adult cats require different vaccination schedules to ensure full protection:
Kitten Vaccination Schedule (Initial Protection)
- 6-8 weeks old – First vaccination (Core vaccines: Feline Enteritis, Calicivirus, Herpesvirus)
- 10-12 weeks old – Second vaccination (Booster for core vaccines)
- 14-16 weeks old – Third vaccination (Final booster for full protection)
Adult Cat Vaccination Schedule (Ongoing Protection)
- Annual or tri-annual boosters – Depending on the type of vaccine, cats need yearly or every three-year boosters to maintain immunity.
Regular boosters are essential to keep your cat protected throughout their life.
Why Are Regular Vaccinations Important?
Keeping your cat’s vaccinations up to date is essential for their long-term health. Here’s why regular vaccinations are necessary:
- Prevents Deadly Diseases – Many of the diseases we vaccinate against have no cure and can be fatal. Prevention is the best protection.
- Protects Kittens When They’re Most Vulnerable – Young kittens have weaker immune systems and rely on vaccinations to build strong immunity.
- Stops Disease Spread in Multi-Cat Households – If you have more than one cat, vaccinating them helps prevent disease transmission.
- Required for Catteries and Boarding Facilities – Most boarding facilities require up-to-date vaccinations before accepting cats.
- Saves You Money on Costly Vet Bills – Treating severe diseases like feline enteritis or FIV can be expensive and difficult to manage.
Are Vaccines Safe for Cats?
Yes, vaccines are carefully tested and proven to be safe and effective. Some cats may experience mild side effects like slight lethargy or soreness at the injection site, but these usually resolve within a day or two. Serious reactions are extremely rare.
If you have concerns about vaccinations, speak with your vet – they can answer any questions and tailor a schedule to suit your cat’s health needs.
