In Australia, the devastation to our native fauna caused by the natural predatory instincts of feral and domestic cats is staggering and causing dire biological consequences. In May, the internet was shocked by an image from a wildlife detection camera near the Queensland - Northern Territory border capturing a large feral cat carrying a sand goanna, which can weigh up to six kilos. Through our own environmental project work in southern Queensland, we too have discovered plenty of cats on cameras in areas where we were searching for wildlife.
The predatory habits of cats see them target a range of wildlife species. Larger animals like kangaroos, wedge-tailed eagles and dingoes are safe from cat predation, but almost every other Australian species fall into the category of prey.
Feral felines
For decades, organisations like the
Australian Wildlife Conservancy
(AWC) and Biosecurity Queensland have conducted research to assess the habits and habitats of feral cats, their negative impact on Australia’s native wildlife and how those impacts can be lessened and/or eradicated.
A variety of methods have been employed (with varying success rates) including labour-intensive camera-trap monitoring, GPS tracking collars, population density recording and consultation with First People trackers.
A report co-authored by Biosecurity Queensland (cited by
ABC News) estimates “there are as many as 5.6 million feral cats across 99.8 per cent of the country”.
With each feral cat killing 740 animals on average per year, the data shows around one billion mammals, 596 million reptiles, and 316 million birds are killed annually. That’s around 1.91 billion less bilbies, frogs, rosellas, sand goannas, cockatoos and wallabies (to name just a few of the threatened and endangered species who become prey to these highly efficient hunters). It's no wonder Australia is in an extinction crisis, with the worst mammalian extinction rate of any country in the world.
Domestic danger
Closer to home, new research has found domestic cats are causing similar deaths and destruction to local wildlife populations.
An April 2020
Wildlife Research report
by CSIRO Publishing states that while domestic cats kill an average of 186 animals per year, (a quarter of a feral cat’s kill rate), their kills have a higher concentration rate in one area e.g. a town or city – 50 times higher per unit/area. Domestic cats also appear to make no distinction between introduced species e.g. rats and mice, versus native ones.
A 2019
Animal Medicines Australia survey
found that of the 61 per cent of Australian households who own pets, 27 per cent of those are cats. Factoring in these findings combined with domestic cats living longer than feral cats, the severity and extent of the devastation cats pose to Australian’s native wildlife is alarming.

Tips for protecting wildlife from your feline assasin
If you have a cat, there are a number of precautions you can take to be a responsible pet owner, including spading. (Your vet will agree.)
No councils within the SQ Landscapes region require cats to be kept indoors at all times. However, all councils have regulations and recommendations regarding microchipping, de-sexing and monitoring your cat, so it’s important to regularly check your regional council's website for updates and information about mitigating the risk.
All of the information and research shows that cats kept inside aren't a danger to wildlife. Keeping cats in also protects your pet from becoming victims themselves. Pets are hit and killed by cars often, while wandering animals are prone to fighting with other cats or dogs, or catching diseases.
If you can’t keep your cat inside all the time, here are some tips for being a responsible pet owner;
• Dusk, dawn and evenings are when many nocturnal animals are waking up and beginning to move around looking for food. It’s important to keep your cats inside during these times, but all times is best.
• Make sure your cat is de-sexed to prevent an increase of unwanted strays with nowhere to be but outside with no other option for food.
• Start the routine of being indoors from a kitten. Only feed and play with your cat inside, so they know to come/stay inside for affection and sustenance.
• If possible, create an enclosed outdoor space on your balcony, patio or in your backyard.
• Put a bell or a reflective mirror on your cat’s collar, to make them less effective at stalking.
