There are many small marsupials (mammals) in Australia that are predated on by feral and domestic cats. https://en.wikipedia.org/wiki/Cats_in_Australia https://en.wikipedia.org/wiki/Cats_in_Australia We have a cat that was rescued from a neglectful neighbour. We were shocked one night when it turned up at our back door with a live pet rabbit is had nabbed from a house a few doors away. Thankfully the cat mostly has since caught non-native mice and grasshoppers since (that we are aware of). The best conservation efforts at restoring native animal populations in Australia have been achieved through cat and fox proof fencing followed by trapping, baiting and shooting programs: https://www.australianwildlife.org/sanctuaries/mt-gibson/ https://www.australianwildlife.org/sanctuaries/mt-gibson/
