The Impact of Feral Cats on Wildlife

Feral cats pose a considerable threat to Australian wildlife, with astonishing statistics indicating that they consume twelve birds every second. This dramatically impacts biodiversity, leading to a significant decline in bird populations. The life expectancy of feral cats is notably shorter than that of domestic cats, with only two years in the wild, pushing them to exploit various food sources, including native fauna. Research shows that removing feral cats from certain outback regions can lead to a resurgence in biodiversity, restoring ecosystems that were once rich in different species.
