Australia is the only island in the world that has all types of climates, and because of that the fox has established itself rather solidly. The animals that are native to this country have not evolved to defend themselves against this environmental demon, due to the circumstances under which the fox was introduced. The introduction of the fox was so sudden that native animals were slaughtered in order to feed the young of this carnivorous, feral fiend. So naturally, with all the rabbits around to help sustain the population of foxes, this prime predator has become the top of the food chain.
Like feral cats, the fox is a territorial animal, but these pests do have a social structure that concentrates on the dominant female. The boundaries, just like a feral cat, are marked with the foxes wastes. Foxes are seasonal breeders. This means that the species doesn’t breed all year round. They only breed for a short period if time in mid-winter (Australian winters are from June-August). This is generally from early July-late August.
