Gregory Andrews, Australia's first Threatened Species Commissioner says Environment Minister Greg Hunt is leading the charge.
"Of the 29 mammals that we've lost to extinction, feral cats are implicated in 28 out of those 29 extinctions, and over 120 Australian animals are at risk of extinction from feral cats," Andrews told the Australian Broadcasting Corporation. "It's very important to emphasise too that we don't hate cats. We just can't tolerate the damage that they're doing anymore to our wildlife."

Researchers have found that much of the Australian species' decline coincided with the introduction of two animals: the feral cat, which sailors brought to Australia on ships as a means of pest control, and red foxes, brought to the continent for hunting.

In this Feb. 6, 2013 photo, a feral cat eats cat food from a box left by a cat lover behind a grocery store in Key Largo, Fla. While hunters stalked the elusive Burmese python through large swaths of Florida's Everglades over the last month, state and federal wildlife officials set traps for other animals menacing native wildlife in a fragile ecosystem. The python gets all the attention in Florida's sometimes weird animal kingdom and it's accused of decimating the populations of native mammals in the Everglades, but wildlife officials say feral cats, black-and-white tegu lizards and Cuban tree frogs are some of the other invasive species that pose equally serious threats to imperiled native wildlife in the swamplands and neighboring habitats.

According to the Washington Post, feral cats are the biggest threat to endangered mammals in Australia, a country that has one of the worst extinction records in the world. Some of the mammals on the verge of extinction include the greater bilby, eastern bettong, western quoll, and the numbat.
The government is asking Australian cat owners to contain, desex, and microchip their pets to aid the initiative.
