RE: Red foxes (Vulpes vulpes) were introduced to Australia for sport hunting in the 19th century, but ended up being responsible for the extinction of several native species, including the desert rat-kangaroo (Caloprymnus campestris)

It's important to remember that the small species who get eaten by the foxes also have a right to live. And the red fox species as a whole does not really belong in Australia, but species such as kangaroos and koalas do, so I prefer the latter one to stay alive more than the red fox :) Thanks for the comment!
