I think instead we should have a cull of humans. Foxes have every right to life, just as we do. They're doing what comes naturally, looking for food. As stated, one factor is the usual selfish slobbish and lazy actions of humans and their habits which increases the likelihood of fox/human interaction. Just because humans are (in some cases) more intelligent than animals, and some have better and more sophisticated (allegedly) methods of communication than animals doesn't mean humans have the right to kill animals who are an inconvenience or seen as 'vermin'. Humans don't have the ability to live in harmony with their surroundings, ever expanding and resource consuming. This is the problem.
We don't know the full facts, only what we hear on the 'news' and in the 'media', which is all designed to help control us anyway, but on the face of it, why the hell was a young baby left unsupervised with an open door/window in the house.
It's not too long ago there was a thread about the potential killing of sharks that had attacked swimmers and surfers, and IIRC the general jist of that thread was that the surfers etc had entered the sharks environment and a two foot wife razor sharp mouth biting them in half was to be expected. Rightly so. What's the difference with foxes? The habitat they once had and shared with all has been turned into a concrete jungle, so what are the foxes to do, migrate?
