My grandad's big old house on the shore in Edinburgh has a large contingent of urban foxes. There seem to be two or three seperate families – the garden is big enough for them to all play nicely most of the time.
They have no problem with sunbathing in the middle of the lawn for half the day, just lolling about and play fighting. They also wander through many of the neighbouring gardens and disappear off down the old railway line at the back of the house. Not very timid really.
They're not too keen on my dog though, as he tends to want to kill them – he's had at least two fights with the foxes and had a big, nasty cut over his eye after the last one. He's not a big dog – lurcher / terrier cross and he doesn't even have any b@lls left, poor chap, but he does like a pagger with Mr Fox.
