I'm taking a fairly relaxed attitude to the foxes too. I severely doubt that something the size of a fox is going to attack something the size of an adult human unless it's cornered, defending its cubs, or rabid (and the UK is still a rabies-free zone). I expect that foxes are mostly a threat to dustbins (which I can live with), and possibly small unattended children (which are not something we have to worry about).
