Cats are scientifically, objectively, monumentally terrible for the planet. In the US alone, free-ranging domestic cats kill up to 3.7 billion birds and 20.7 billion mammals a year, to say nothing of reptiles and amphibians. They are a scourge of the highest order.

Now felines are poised to exacerbate the ecological crisis unfolding in Australia as an unprecedented fire season rips across the continent. Scientists have previously shown that feral cats hunt surviving animals across recently burned lands in Australia, exploiting many of the victims’ injured or weakened state. One study found that a feral cat journeyed 19 miles to a burn scar. Roaming cats might stay away for up to 50 days, massacring helpless locals on a now barren landscape. (They’re likely using a combination of sight and smell to pinpoint bushfires by their smoke.)
