What You'll Learn
Feral cats eat about 1.5 billion reptiles a year
Feral cats in Australia are an extremely destructive invasive species that prey on a wide range of native wildlife, including reptiles. The Australian government has declared them pests, and they are recognised as an extreme threat category. Feral cats have been linked to the extinction of numerous mammal species and are currently endangering many more. They are also known to carry and spread diseases and parasites that can be transmitted to humans, wildlife, and livestock, causing significant economic losses.
Feral cats are highly adaptable and opportunistic predators, and their diet consists of small to medium-sized mammals, birds, reptiles, amphibians, fish, and insects. They prefer to hunt live prey rather than scavenging and will go after anything smaller than themselves. In pastoral regions, they primarily feed on young rabbits, while in other areas, they predominantly prey on native animals.
The impact of feral cats on Australia's reptile population is significant. It is estimated that feral cats in Australia consume about 1.5 billion reptiles each year. This includes lizards, snakes, and other reptiles. Some studies suggest that feral cats in Australia eat more than a million lizards per day, pushing some reptile species towards extinction.
The high predation rate by feral cats is putting severe pressure on local populations of certain reptile species. There is substantial evidence that cats are a primary cause of the ongoing decline of some threatened Australian reptile species, such as the great desert skink. This has led to various control measures being implemented by the Australian government, including shooting, trapping, fencing, and baiting.
The Australian government has also invested in developing specialised baits, such as Curiosity® and Eradicat®, to minimise the risk of native animals being poisoned and reduce the feral cat population in a humane and effective manner. These efforts are crucial in mitigating the environmental, agricultural, and human health impacts of feral cats in Australia.

They also eat mammals, birds, frogs and invertebrates
Feral cats in Australia are highly successful invasive pests and are considered one of the most threatening invasive species worldwide. They are medium-sized predators and descendants of domestic cats, but survive in the wild without human reliance or contact. They are opportunistic and ambush predators, needing to eat meat to survive as they cannot digest plant carbohydrates. They prefer to hunt than scavenge and will go after anything smaller than themselves.
Feral cats in Australia eat mammals, birds, frogs, and invertebrates. They generally eat small mammals, but also catch larger prey, such as wallabies. They are responsible for the extinction of more than 20 Australian mammal species, including the pig-footed bandicoot, lesser bilby, and broad-faced potoroo. They have also contributed to the decline of many land-based threatened animals, such as the bilby, bandicoot, bettong, and numbat. In pastoral regions, they feed largely on young rabbits, but in other areas, they prey mainly on native animals.
Feral cats also eat birds, and it is estimated that they kill 316 million birds in Australia each year. They are a recognized threat to over 200 nationally threatened species and 37 listed migratory species. They also eat frogs and are known to prey on small to medium-sized amphibians.
Invertebrates are also part of the diet of feral cats in Australia, and they are estimated to kill over 1 billion invertebrates each year. This includes insects, which they catch and eat along with other small creatures. Overall, a single feral cat eats, on average, 791 mammals, birds, reptiles, and frogs, and 371 invertebrates each year.

In pastoral regions, they eat mostly young rabbits
Feral cats in Australia are considered a highly successful invasive pest species and are listed as one of the most threatening invasive species worldwide. They are the same species as domestic cats but survive in the wild without human contact or reliance. They are a major cause of the decline of many land-based threatened animals and have contributed to the extinction of more than 20 Australian mammal species.
Feral cats are opportunistic predators and will eat a wide range of wildlife species. They generally eat small mammals but also catch birds, reptiles, amphibians, fish, and insects. They are estimated to eat about 1.5 billion reptiles, birds, frogs, and mammals each year, and more than a billion invertebrates. A single feral cat eats, on average, 791 mammals, birds, reptiles, and frogs, and 371 invertebrates each year.
The Australian government has recognized the threat posed by feral cats and has initiated various control measures, including shooting, trapping, fencing, and baiting. They have also developed the Curiosity® bait, a small meat-based sausage containing a humane toxin designed to minimize the risk of native animals being poisoned.

They are a threat to over 200 nationally threatened species
Feral cats in Australia are a highly successful invasive species, and a significant threat to native wildlife, agricultural industries, and human health. They are recognised as a key threatening process under the Environmental Protection and Biodiversity Conservation Act 1999. Predation by feral cats is a threat to over 200 nationally threatened species and 37 listed migratory species.
Feral cats have contributed to the extinction of more than 20 Australian mammal species, including the pig-footed bandicoot, lesser bilby, and broad-faced potoroo. They are also a major cause of the decline of many land-based threatened animals, such as the bilby, bandicoot, bettong, and numbat. They are extremely adaptable and opportunistic predators, and their diet consists of a wide range of wildlife species, including small mammals, birds, reptiles, amphibians, fish, and insects.
Feral cats have a particular impact on threatened reptile species, with studies showing that they eat over a million lizards a day, and are pushing some species to the brink of extinction. They are also a threat to birds, with estimates suggesting that they kill 272 million to 316 million birds in Australia annually.
The Australian government has recognised the threat posed by feral cats and has implemented various control methods, including shooting, trapping, fencing, and baiting. The government has also invested in the development of humane toxins to target feral cats specifically, such as the Curiosity® bait, which contains a hard plastic pellet with a toxin that minimises the risk of native animals being poisoned.
Feral cats are a significant problem in Australia, and their impact on native wildlife, particularly threatened species, is devastating. The government's efforts to control their population and protect vulnerable species are ongoing.

They have contributed to the extinction of over 20 mammal species
Feral cats in Australia have contributed to the extinction of over 20 mammal species. They are a highly successful invasive pest in Australia and are considered one of the most threatening invasive species worldwide. They are the same species as domestic cats but survive in the wild without human contact or reliance. They are a declared species under the Biosecurity and Agriculture Management Act 2007 (BAM Act) and are considered pests in Western Australia under the BAM Act.
Feral cats are medium-sized predators that have a significant impact on the environment and native wildlife. They are ambush predators and carnivores, requiring meat to survive as they cannot digest plant carbohydrates. They prefer to hunt for their food rather than eat carrion and will target anything smaller than themselves. Their prey includes small- to medium-sized mammals, birds, lizards, insects, and fish. In pastoral regions, they primarily feed on young rabbits, while in other areas, they prey on native animals.
Feral cats are opportunistic and adaptable, allowing them to spread rapidly across Australia. They are present across 99.8% of the continent and can weigh up to nine kilograms. They breed successfully, with each female producing two to three litters per year, each consisting of three to four kittens. Their reproductive success is driven by food abundance, and they can produce up to six kittens per litter.
The impact of feral cats on native species is severe. They are recognised as a key threatening process under the Environmental Protection and Biodiversity Conservation Act 1999. Predation by feral cats has been linked to the extinction of over 20 mammal species in Australia, including the pig-footed bandicoot, lesser bilby, and broad-faced potoroo. They continue to drive population decline in Australian native animal species, endangering 147 Australian mammals, birds, reptiles, and frogs. Overall, they kill over 1.5 billion native mammals, birds, reptiles, and frogs annually, with a single feral cat consuming, on average, 791 of these animals each year.
To mitigate the impact of feral cats, the Australian government has implemented various control methods including exclusion fencing, baiting, trapping, and shooting. The government also led a $7 million project to develop the Curiosity® bait, a humane toxin-containing meat-based sausage designed to minimise the risk of native animal poisoning. Additionally, the Australian Wildlife Conservancy activated a 27-mile-long electric cat-proof fence to create a 23,000-acre cat-free preserve in Central Australia.
