Navigating parasite prevention for your cat can feel like a bit of a puzzle. With so many spot-ons, tablets, and collars available, it’s easy to wonder if you’re actually covering all the bases - or perhaps doubling up unnecessarily.
In Australia, our unique climate means parasites like the deadly paralysis tick are a constant concern, making a solid prevention plan essential. Whether your cat is a sun-drenched adventurer or a dedicated indoor lounge-warrior, getting the right balance of protection is the best way to ensure they stay happy, healthy, and itch-free.
Parasites of concern for Australian cats
- Fleas: Small wingless bloodsucking insects that live on your cat's body and lay eggs in the environment. These guys cause intense itching and dermatitis.
- Ticks: Another wingless bloodsucking insect. There are 3 species in Australia: The Paralysis Tick, The Brown Dog Tick, and the Bush Tick. However unlike fleas, paralysis ticks inject a paralysing toxin which can be lethal. Only the Paralysis Tick is venomous.
- Heartworm: blood-dwelling worms transmitted by mosquitoes. While cats aren't the natural host of heartworm, they can still be infected by a mosquito which has recently fed off an infected dog.
- Intestinal worms: Worms that live in the gastrointestinal tract including hookworm, roundworm and tapeworm.

What coverage does your cat actually need?
We recommend regular flea, heartworm and intestinal worming protection for all cats, whether indoor or outdoor. Some parasites may not pose a risk to your cat, depending on your area or lifestyle.
Do I need to cover ticks?
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.
Do I really need to cover for tapeworm?
With so many preventatives lacking tapeworm coverage (such as Bravecto Plus and Revolution Plus), many pet owners wonder if tapeworm is really that important.
Tapeworm is most commonly transmitted to cats from fleas and hunting and eating prey such as lizards and rodents. Ultimately, we recommend tapeworm prevention for every cat. Products that cover tapeworm include Drontal, Paragard, Milbemax, Milpro and topical Profender.
What treatment covers for all cat parasites?
Nexgard Spectra
Until recently there was no true all-in-one product for cats. Fortunately, NexGard Spectra has now hit the market as the first true all-in-one that protects your cat against ticks, fleas, heartworm and intestinal worms, including tapeworm!
There are some other great products that come very close including Bravecto Plus and Revolution Plus which cover fleas, heartworm, intestinal worms - and ticks. The only major parasite not covered is tapeworm.
NexGard Spectra protects your cat against:
- Fleas
- Paralysis & Bush Ticks
- Mange and Ear Mites
- Heartworm disease
- Intestinal worms like Roundworm, Hookworm and Tapeworm
- Lungworm
Protecting your cat from ear mites and 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, occuring mostly in kittens or immunocompromised adult cats. Products that protect against ear mites include Bravecto, Bravecto Plus, Advocate, Revolution Plus and Revolution.
Cats can also be infected by lungworms. 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 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.
