Cat Vaccinations: A Complete Guide for Melbourne Cat Owners

Cat vaccinations are often less discussed than dog vaccinations — but they're equally important. Cats can be exposed to serious, potentially fatal diseases even with limited outdoor access, and some diseases can be transmitted indirectly through clothing, shoes, or shared equipment.

Core Cat Vaccinations (F3)

The F3 vaccination protects against three diseases that are widespread in the Australian cat population:

• Feline herpesvirus (rhinotracheitis) — causes severe upper respiratory infection; can become a lifelong recurring condition
• Feline calicivirus — another cause of respiratory disease and oral ulcers
• Feline panleukopenia (parvovirus) — a potentially fatal disease affecting the gut and immune system

These three diseases are so common and so serious that the F3 is considered essential for all cats, regardless of whether they go outdoors.

Optional Vaccinations

FIV (Feline Immunodeficiency Virus)

FIV is transmitted primarily through bite wounds during cat fights. If your cat goes outdoors — even occasionally — FIV vaccination is strongly recommended. The vaccine requires an initial course of three injections given 2–4 weeks apart, then annual boosters.

Kitten Vaccination Schedule

1. 16–8 weeks: First F3 (usually given by breeder or rescue)
2. 210–12 weeks: Second F3 + FIV first dose (if recommended)
3. 314–16 weeks: Third F3 + FIV second dose
4. 46 months: FIV third dose (if applicable)
5. 512–16 months: First adult booster
6. 6Every 1–3 years: Ongoing F3 boosters
7. 7Annually: FIV booster (if applicable)

Indoor Cats: Do They Still Need Vaccinations?

Yes — though the frequency may differ. Herpesvirus and calicivirus can be carried in on your hands or clothing. Panleukopenia is extremely hardy and can survive in the environment for years. We recommend maintaining core vaccinations for all cats, with the interval between boosters potentially extended to every 3 years for strictly indoor cats after the initial course.
