This doesn't compare with a big cat of course, but had a fox cub experience earlier on today which was pretty cool - no camera or even phone though.
So I was stood in a trackway when I spotted a young fox cub bimbling along further down and coming towards me, exploring the ground and smelling everything. Not sure how old it would have been but it was maybe a touch larger than the largest domestic cat you normally see out. Anyway it seemed quite young and spent a few moments worrying about a hogweed leaf blowing about in the middle of the way. I was in the middle of eating a banana at the time so I broke a few chunks off and threw them down the track about 30 feet away. It hadn't noticed me, but ate the banana when it came to it! It was only when it kept coming toward me and about 10 feet away that it saw me and legged it back without a backward glance. Saw an adult too in the vicinity wandering about a couple of times that afternoon too.
Nice one! Who doesn't like a banana? Certainly not an opportunistic omnivore like a fox.
That'll teach you to let your camera out of arms reach - clear breach of Rule 1! :-O
