Feral Cats Are An Invasive Species in North America (and elsewhere)

10,000 Birds

I once knew a guy who kept and raised cats. You can make a similar map for the small carnivores, the Mustelids, such as minks, ermines, otters, etc. Dogs are similarly dispersed across size ranges, with Foxes, Coyotes, and Wolves taking prey across different parts of the size range. But they don’t live in North America.
