Cats in Australia

Feral cats are an invasive species in Australia. Because they are not native to Australia and were only introduced by European colonists as pets in the early 1800s, native Australian animals did not co-evolve with them.[1] As of 2016, some 3.8 million domestic cats and up to 6.3 million feral cats continue to live in Australia.[2][3][needs update]

The Invasive Species Council has estimated that each year domestic and feral cats in Australia kill 1,067 million mammals, 399 million birds, 609 million reptiles, 93 million frogs, and 1.8 billion invertebrates.[4] As one of the most ecologically damaging and the most costly invasive species in Australia, predation by both domestic and feral cats has played a role in the extinction of many of Australia's indigenous animals. For instance, cats are found to have significantly contributed to the extinction of at least 22 endemic Australian mammals since the arrival of Europeans.[5]

For biosecurity reasons, any cats that are imported into Australia must meet conditions set by the Department of Agriculture, Fisheries and Forestry.
