Kitten first-year planner for Western Australia: vaccines, sterilisation and registration
In Western Australia, every cat must be microchipped, sterilised and registered with the local government by 6 months of age, and kittens can't be sold or given away unless they are microchipped. Before then come three F3 vaccinations between 6 and 16 weeks and regular worming.

- InsuranceNow
Insure your kitten before any waiting period can bite
Pet insurance won't pay for anything that shows signs during its waiting period. All six policies we compare cover cats: illness cover starts after 14 to 30 days, and some specified conditions after up to 6 months. Anything that appears before cover starts can be excluded for life, so insuring while your kitten is young and healthy matters most.
- ParasitesNow
Use cat-safe flea and tick products only
Never put a dog flea or tick treatment on a cat. Many dog spot-ons contain permethrin, which cats can't break down; even a standard dose for a small dog can kill a cat, and it is the most common way cats are poisoned. If you also have a dog, keep your kitten away from it for at least 72 hours after treating the dog. On the east coast, paralysis ticks affect cats too, so ask your vet for a kitten-safe preventative.
- Parasites2–24 weeks
Worm your kitten every 2 weeks, then monthly
Kittens are commonly wormed every 2 weeks until 12 weeks old, then monthly until 6 months, then every 3 months as adults. Use an all-wormer made for cats that covers roundworm, hookworm and tapeworm.
- Vaccine6–8 weeks
First F3 vaccination
The core F3 vaccine protects against feline panleukopenia (feline enteritis), feline calicivirus and feline herpesvirus (cat flu). The first dose is given at 6 to 8 weeks, often before your kitten comes home, so check the vaccination card you received.
- Behaviour8–10 weeks
Keep up gentle kitten socialisation
A kitten's sensitive period starts at about 2 weeks and begins to wane between 7 and 10 weeks, so much of it happens with the breeder. Carry it on at home: short, calm handling sessions, touching paws and nails, time in an open carrier, short car trips and a clean litter tray in a quiet spot. Let your kitten approach at its own pace.
- Vaccine10–12 weeks
Second F3 vaccination
The next F3 dose comes 2 to 4 weeks after the first. Your vet may also discuss non-core vaccines, such as feline leukaemia or FIV, depending on whether your cat will go outdoors.
- Vaccine16 weeks
Final kitten vaccination at 16 weeks or later
The last kitten dose should not be given before 16 weeks, because antibodies from the mother can stop earlier doses from working in some kittens. Your kitten isn't fully protected until 7 to 14 days after this dose.
- Vaccine26–68 weeks
Your cat's first adult booster
The first adult booster is traditionally given about 12 months after the last kitten vaccination, though current guidelines allow it from 6 months of age. Your vet will then set an ongoing schedule, and an annual health check is recommended either way.
- Legal requirement6 months
WA: microchip, sterilise and register your kitten by 6 months
Under WA's Cat Act 2011, every cat must be microchipped, sterilised and registered with the local government by 6 months of age, and must wear a collar with its registration tag. If you got your kitten too young to be sterilised, the seller should have given you a prepaid sterilisation voucher.
- Legal requirementEvery 31 October
WA: cat registration runs to 31 October
WA cat registrations end on 31 October, and the tag colour changes each year. You can also choose lifetime registration so there is nothing to renew.
