Which parasites does your cat need protection from?
Cats need cover from a few different parasites, and how much depends on whether they roam, hunt or stay indoors:
- Fleas cause itching and can trigger a flea allergy, and they also pass on tapeworm when a cat grooms.
- Ticks, including the paralysis tick along the east coast, can make a cat seriously ill.
- Intestinal worms (roundworm, hookworm and tapeworm) affect the gut, and hunting cats pick them up from prey.
- Heartworm, spread by mosquitoes, is less common in cats than dogs but has no treatment, so prevention is the only option where risk is high.
An indoor cat is lower-risk but not no-risk, since fleas hitch a ride inside and worms can arrive on prey or other pets. Your vet can help you match cover to your cat's lifestyle and where you live.
All-in-one or separate treatments?
The first decision is whether one product can cover what your cat needs, or whether you combine two:
- All-in-one spot-ons like Revolution Plus, Bravecto Plus and NexGard Spectra for cats cover fleas, worms and other parasites in one monthly or longer dose, which is the simplest way to avoid gaps.
- A flea product plus a separate wormer suits cats already on a preventative that does not cover worms, or where you prefer to worm on your own schedule.
- Mind the gaps: some products, including Advocate, cover fleas and worms but not ticks, so in tick areas check what your product actually covers. Choosing between the two most common all-in-ones? Our vets compare them in Advocate vs NexGard Spectra for Cats.
Why most cat treatments are spot-ons
Cats are famously hard to give a tablet, so most cat parasite products are spot-ons applied to the skin at the back of the neck, where your cat cannot lick them off. That makes application quick and avoids the wrestle of a pill. Wormers are the main exception and do come as tablets, such as Milbemax and Milpro, and many cats take these more easily hidden in food. Choose the format your cat will actually tolerate, because the best treatment is the one you can keep up.
Worming your cat
Cats get three main intestinal worms: roundworm, hookworm and tapeworm. Tapeworm is the one most tied to lifestyle, because cats catch it both from fleas and from hunting, which is why flea control and worming go hand in hand. Most adult cats need worming every three months, while kittens need it far more often. Worm to your cat's weight and always follow the directions on the pack. Heartworm is a separate, mosquito-borne worm that a standard wormer does not cover, so ask your vet whether heartworm prevention is needed where you live.
Ticks and cats
Cats can get the paralysis tick too, mainly along the east coast, and it causes the same progressive paralysis it does in dogs. Fewer cat products cover paralysis ticks than flea-only products do, so if you are in tick country choose one that specifically lists paralysis ticks, such as Bravecto or NexGard Spectra for cats, and check your cat by hand during tick season. If you find a tick or your cat seems wobbly, off their food or is breathing differently, contact your vet straight away.
Trusted cat parasite brands
Australia's leading cat parasite brands differ mainly in what they cover and how they are given:
- Revolution Plus: a monthly all-in-one spot-on covering fleas, ticks, mites and intestinal worms.
- Bravecto: spot-ons for cats giving flea and paralysis tick cover for up to three months.
- Advocate: a monthly spot-on for fleas, heartworm and intestinal worms (no tick cover).
- Milbemax and Milpro by Virbac: small all-wormer tablets sized for cats and kittens.
Fleas, ticks and worms in kittens
Kittens need earlier, more frequent cover than adult cats, and they are more vulnerable to a heavy flea burden, which can cause anaemia. Use only products labelled for your kitten's age and weight, worm more often while they are young, and treat the mother and any other pets at the same time. Browse kitten flea, tick and worm treatments suited to little ones, and confirm the schedule with your vet.

Frequently Asked Questions
Most cats need flea and tick prevention monthly, or up to every three months with a longer-acting spot-on, and worming every three months for adults. Kittens need worming far more often while they are young. The exact interval is set by the product, so follow the pack and keep to the schedule without gaps, which is what maintains protection.
Yes, indoor cats still need flea and worm prevention, just often at a lower intensity than outdoor cats. Fleas come inside on shoes, other pets and visiting animals, and worms can arrive on prey a cat catches indoors or on a dog in the home. Your vet can help you set a routine that matches a mainly-indoor lifestyle.
You can sometimes see worms in a cat's poo or around their rear, most often tapeworm segments that look like grains of rice, or spaghetti-like roundworm. Many worms stay invisible, though, so a clear stool does not mean your cat is worm-free. Regular worming is the reliable way to stay ahead of them, and any blood, mucus or ongoing diarrhoea warrants a vet visit.
Natural flea and worm products for cats need real caution, because some essential oils that are marketed as natural are actually toxic to cats. They also tend to offer only limited, short-lived protection and do not reliably cover serious threats like paralysis ticks or all intestinal worms. Registered veterinary treatments are the dependable choice, so ask your vet before trying any natural alternative.
A good cat treatment is one labelled specifically for cats, matched to your cat's weight, that you can actually apply on schedule. Decide whether you need an all-in-one spot-on or a separate flea product and wormer, and whether tick or heartworm cover matters where you live. Your vet can help you match the right product to your cat's age and lifestyle.
