When cats roam free, small wild animals die. And the body count in Australia exceeds 2 billion native animals per year.
Environmental researchers in Australia compiled the alarming figure by combing through hundreds of studies on the predatory habits of Australia's free-ranging pet cats as well as feral felines. The scientists documented cats' historic and ongoing toll on Australian wildlife in the book "Cats in Australia" (CSIRO Publishing, 2019).
