Not sure where to start with parasite prevention? With so many spot-ons, tablets, and collars available, it's easy to wonder whether you're actually covering all the bases. This guide walks you through what your cat needs based on where you live and how they spend their days.
For specific product recommendations, see our Best Cat Flea, Tick and Worming Treatments guide.
What parasites do all Australian cats need protection from?
Every cat in Australia, indoor or outdoor, needs year-round protection from three things:
Fleas cause intense itching and skin irritation, and can spread tapeworm. Flea eggs fall off your cat into carpet, bedding, and soft furnishings, which makes them very hard to fully eliminate once established.
Heartworm is transmitted by mosquitoes, so even indoor cats are at risk. While cats aren't the natural host, infection can cause serious lung disease.
Intestinal worms, including roundworm, hookworm, and tapeworm, can be picked up from the environment, infected prey, or even from fleas during grooming.
For a full overview of each parasite and its symptoms, see our Flea, Tick and Worm Guide for Cats.
Does my indoor cat need parasite prevention?
Yes. Indoor cats are lower risk for some parasites, but they're not fully protected. Fleas can hitch a ride indoors on other pets, clothing, or nearby wildlife. Worm eggs can be carried in on shoes or soil. And mosquitoes can easily access your home, making heartworm a genuine risk for every indoor cat.
The main parasite indoor-only cats are unlikely to need coverage for is paralysis tick, unless you live along the east coast, they occasionally venture outside or you have other pets that could bring ticks in.
For a full overview of the risk of fleas to indoor cats, see our article answering Can Indoor Cats Get Fleas?
Does my cat need tick prevention?
It depends on where you live. Paralysis ticks live along the eastern coastline of Australia, however cases have been known to occur as far south as Melbourne. Ticks can be seasonal, which means they are less prevalent risk from April to August - however this changes year by year.
The Brown Dog Tick and Bush Tick are more widespread throughout Australia, and though they do not cause paralysis, they can transmit deadly diseases such as Ehrlichiosis (though this is rare in cats).
Although indoor cats are at less risk of exposure to ticks than those that venture outdoors, prevention is better than cure so tick prevention is still recommended in affected areas. For cats living along the east coast of Australia at risk of ticks, we recommend using isoxazoline-based products such as Revolution Plus, Nexgard Spectra or Bravecto Plus.
Does my cat really need tapeworm coverage?
With so many preventatives lacking tapeworm coverage (such as Bravecto Plus and Revolution Plus), many pet owners wonder if tapeworm is really that important.
The two most common tapeworms in Australian cats are:
Flea tapeworm is spread when cats swallow infected fleas during grooming. You may notice small, rice-like segments near your cat's bottom or in their faeces.
Spirometra tapeworm is picked up by hunting geckos, frogs, or fish. Segments are larger with a central zipper-like ridge. This one is particularly important to control in households with young children, elderly, or immunosuppressed people, as they're more vulnerable to illness from Spirometra.
Ultimately, we recommend tapeworm prevention for every cat. Products that cover tapeworm include Drontal, Paragard, Milbemax, Milpro and topical Profender.
To learn more about the types of tapeworm and their risks, see our guide to Tapeworms in Cats.
Does my cat need protection from ear mites or lungworm?
In some areas your pets will need protection from other irritating insects.
Ear mites (Otodectes), are the most common mite seen in cats in Australia, occurring mostly in kittens or immunocompromised adult cats. They cause intense itchiness in the ears and can lead to a dark brown discharge. Products that protect against ear mites include Nexgard Spectra, Bravecto, Bravecto Plus, Advocate, Revolution Plus and Revolution.
Lungworm is less commonly discussed but worth knowing about, particularly for cats that hunt. These parasites live in the lungs and can cause serious airway disease especially in kittens and older cats. Infection occurs through exposure to lungworm larvae, either through drinking dirty water or by hunting and eating infected animals such as snails, slugs, frogs, birds or cockroaches. Products that protect cats against lungworm include Nexgard Spectra, Advocate, Neovet and Profender.
FAQs
Choosing the right protection doesn't have to be a headache. By matching your cat's lifestyle and your local environment to the right product - whether that’s a modern all-in-one like NexGard Spectra or a trusted combination of treatments - you can rest easy knowing they are covered. Always remember to check the label for tapeworm and heartworm coverage, as these are frequently missed in basic treatments. If you are ever in doubt, a quick chat with a vet can help tailor a plan that fits your cat perfectly.
