Feral cats kill more than one million reptiles every day in Australia, a new study showed today, with the staggering slaughter threatening many species.
Cats have wiped out entire populations of some animals in Australia since being introduced by Europeans settlers two centuries ago, with efforts to cull or sterilise them so far failing to slow their march.
The new findings are based on more than 10,000 cat dietary samples contributed by environmental scientists across the country.
In total, around 650 million lizards and snakes fall victim to feral and pet cats annually, they found.
"On average each feral cat kills 225 reptiles per year," said lead researcher John Woinarski, from Charles Darwin University, adding that feral cats consume more reptiles in Australia than in the United States or Europe. "Some cats eat staggering numbers of reptiles. We found many examples of single cats bingeing on lizards, with a record of 40 individual lizards in a single cat stomach."
