Marsupial lions were believed to fill this gap in the food chain. Unfortunately, they died out 60,000 years ago. Now cats and foxes are hunting native species, some faster than is sustainable. Eventually an equilibrium will be found, where the wild cat and fox populations can’t be sustained due to over-hunting, but it will likely come at the cost of many native species disappearing.
