It’s a common belief that indoor cats don’t need regular flea and worming protection. After all, if your cat never goes outside, surely they’re safe from parasites?
In reality, even cats that live exclusively indoors can still be exposed to fleas and intestinal worms, and skipping preventative care can lead to avoidable health problems.
Debunking common myths about Cat Parasites
Common myths that indoor cats are fully protected can create a false sense of security and may put cats at risk. The truth is that parasites like fleas and worms can find their way into any Australian home.
💡Kittens are especially vulnerable, as they can become infected early in life through their mother’s milk or contact with contaminated environments.
1. Fleas can easily enter your home
Fleas don’t need your cat to go outdoors to find them. They can be brought inside on shoes, clothing, bags or by visiting other pets and people. In apartments and townhouses, fleas can also travel between neighbouring homes.
Once indoors, fleas can live and breed in carpets, bedding and furniture. For cats, flea exposure can cause intense itching, skin inflammation, hair loss and, in severe cases, anaemia. Some cats are also allergic to fleas.
Fleas are also a common source of tapeworm infection in cats.
2. Indoor cats can still get worms
Worms aren’t limited to outdoor cats or hunters. Indoor cats can become infected through accidental ingestion of parasite eggs brought into the home, swallowing fleas during grooming, or contact with other pets.
Common intestinal worms can cause digestive upset, poor coat condition and weight loss. Some types of worms can also pose a health risk to humans, particularly young children.

3. Preventative Care reduces health risks
Preventing parasites is far simpler and more affordable than treating an established infestation or infection.
Regular flea and worming protection helps keep your cat comfortable, supports long-term health and reduces the risk of parasites spreading within your household.
It’s also worth noting that the standard pet insurance policies don’t cover conditions that arise from a lack of routine preventative care, making parasite prevention an important part of responsible pet ownership.
💡Cats may have a flea or worm infestation without showing obvious signs of discomfort, even though it may still be negatively affecting their health.
Common parasites in cats
Australia is home to many parasites, but a few common ones pose the greatest risk to cats — including indoor-only cats.
Fleas
Fleas don’t need outdoor access to enter your home. They can be carried inside on people, other pets, or objects and survive year-round in warm indoor environments.
Cats may groom frequently, but grooming alone doesn’t eliminate fleas. Some cats show no obvious signs, while others develop intense itching, skin infections, and infections.
Look out for excessive licking or biting, hair loss (especially near the tail), and flea dirt (small black specks in the coat).
What’s the difference between Fleas and Ticks?
| Fleas vs Ticks | |
| Fleas | Ticks |
| Insect (6 legs) | Arachnid (8 legs) |
| Prefer cats and dogs | Feeds on pets, other animals, & even humans |
| Thrive in warm, humid climates | Most active in warm seasons & bushy areas |
| Multiply rapidly in the home | Found outdoors & can attach for days |
| Causes Tapeworms, Flea Allergy, etc. | Causes local irritation , Tick Paralysis, etc. |
| High risk even indoors | Low risk indoors but still possible |
Intestinal Worms
Cats can pick up worms by grooming contaminated paws, swallowing infected fleas, or eating prey. Cats can get different types of worms:
- Roundworms
- Tapeworms
- Hookworms
Roundworms
Roundworms are widespread and can infect cats of all lifestyles. Kittens are particularly vulnerable and may be infected through their mother’s milk.
Mild infections may cause no symptoms, but heavier infestations can affect digestion and overall health.
Tapeworms
Tapeworms are commonly transmitted through fleas or infected rodents. They live in the intestine and absorb nutrients meant for your cat.
Hookworms
Hookworms attach to the intestinal lining and feed on blood. While less common in cats, infections can be serious – especially in kittens.
Ringworm (Fungal Infection)
Ringworm is a contagious fungal infection affecting the skin and coat. It spreads easily in warm, humid, or crowded environments and can be passed to humans.
Young, unwell, or long-haired cats are at higher risk.
Choosing safe and suitable products
There are many flea and worming products available, but not all are suitable for every cat. Age, weight, lifestyle and health conditions all matter, and it’s essential to use products specifically formulated for cats, as some dog treatments can be dangerous if used on cats.
Occasionally, pet care products are recalled in Australia or updated due to safety concerns. Resources like Compare Pet Products provide access to information like pet product recall listings, which can help owners stay informed when choosing parasite prevention products.
Protection matters, even indoors
Keeping your cat indoors reduces many risks, but it doesn’t completely eliminate parasites. Flea and worming protection remains an important part of keeping indoor cats healthy, comfortable and protected year-round.
Regular prevention, combined with informed pet product choices, helps ensure your indoor cat stays safe from parasites you may never see but shouldn’t ignore.
