One big reason for that is the removal of free-roaming cats and dogs from human habitats. Free roaming cats and dogs have been a part of our society for as long as we've been forming cities, we only recently decided to remove them. Of course it's going to have the knock on effects we're now starting to see, * vermin * food waste * wild animals venturing into cities * etc.
