Kitten Vaccinations: Protecting Your Kitten from the Start

Kittens are playful and curious, but their immune systems are still developing, making them especially vulnerable to serious illnesses. Vaccinations are the safest and most effective way to protect your kitten from preventable diseases, and they play an important role in keeping all cats in our community healthy.

Why Vaccinate?

When kittens are born, they receive some protection from their mother's milk. This borrowed immunity starts to fade between four and twelve weeks of age, leaving a window where your kitten is more vulnerable. Vaccinations help bridge that gap and build lasting protection of their own.

Some of the diseases we vaccinate against spread easily between cats and can be life-threatening. Prevention is always the better path.

What Do We Vaccinate Against?

Feline Herpesvirus (Cat Flu): A common and highly contagious respiratory virus causing sneezing, nasal discharge, and eye infections. Can become a recurring problem even after initial recovery.

Feline Calicivirus (Cat Flu): Another major cause of cat flu, which can also cause mouth ulcers and, in some strains, more severe illness.

Feline Panleukopaenia (Enteritis): A serious and often fatal viral disease that attacks the digestive system and immune cells. Highly contagious and can survive in the environment for long periods.

These three are covered by the F3 vaccination, which is the core vaccine for all cats in Australia.

Feline Immunodeficiency Virus (FIV): FIV weakens the immune system over time, making it harder for your cat to fight off other infections. It is spread primarily through bite wounds, so cats with any outdoor access or contact with unknown cats are at higher risk. A separate vaccination is available and worth discussing for your kitten's lifestyle.

Kitten Vaccination Schedule

• 6 to 8 weeks: First vaccination (F3)
• 10 to 12 weeks: Second vaccination (F3, and FIV first dose if recommended)
• 14 to 16 weeks: Third and final kitten vaccination (F3, and FIV second dose if recommended)
• FIV third dose: Two to four weeks after the second dose, if the course was started
• 12 months: First adult booster
• Ongoing: Annual boosters as recommended

It is important to complete the full course. Kittens' immunity develops at different rates, and gaps between vaccines can leave your kitten unprotected.

Is FIV Vaccination Right for Your Kitten?

This is worth a conversation at your kitten's first visit. Some things to consider:

• Will your kitten ever go outdoors, even briefly or in a secure enclosure? Outdoor access increases the risk of exposure to FIV-positive cats.
• Could your kitten come into contact with cats of unknown status, including visiting cats, strays, or new household additions?
• Is there any chance of cat-to-cat fighting? FIV is mainly spread through bite wounds, so even a single fight can be a risk.

We will help you weigh these factors at your appointment and make the recommendation that suits your kitten's situation.

Common Questions

Do indoor cats really need vaccines?
Yes. Indoor cats can still be exposed to viruses through humans, other pets, or brief outdoor escapes. The core F3 vaccine is recommended for all cats regardless of lifestyle.

Are there side effects?
Most kittens handle vaccinations very well. Mild tiredness or a little tenderness at the injection site for a day or two is normal. Serious reactions are rare, and we monitor your kitten closely. Contact us if you notice vomiting, unusual swelling, or any behaviour that concerns you.

Does my kitten really need all three initial vaccines?
Yes. The series is designed this way because kittens' maternal immunity fades at different rates. Without completing the full course, some kittens may not develop adequate protection.

What if we miss a scheduled vaccine?
Contact us as soon as possible. Depending on the gap, your kitten may need to restart part of the course. We will advise on the safest plan.

After Your Kitten's Vaccination

• Keep your kitten calm and comfortable for the rest of the day
• Avoid strenuous activity for 24 hours
• Keep their vaccination certificate somewhere safe. You will need it for boarding, grooming, and travel
• Book the next appointment before you leave so the schedule stays on track
