Needs little description, Feral Cats are common across the state. They are one of Wisconsin's worst invasive species, devastating to our population of birds and small mammals.
Statewide.
All habitats, often (but not always) near humans.
Huge range is size, averages about 18" without tail (tail length averages 12"). Some individuals in Australia have been recorded at 16' long with a 23" tail. This has never been recorded in North America but there is no reason it could not.
