Yesterday morning we discovered what looks like a bite on his neck - not deep but quite extensive. We were puzzled and assumed it must have been from a passing dog or possibly a feral tom we know of. Thankfully it's healing well and doesn't appear to bother him at all.
Then this evening I found him hovering in front of his cat-flap (not like him). I wandered over to see what the problem was and saw a very skinny fox sitting against a wall watching him from directly, about 2 metres away. Now of course I'm convinced it was the fox (or another fox) that bit him and that it is purposefully stalking him and out to get him. It doesn't help that another cat who lived in this same house some 10 years ago is rumoured to have been eaten by a fox. We live in a rural area and the house is set back from the road, so there are no doubt plenty of them about.
We won't be letting him out after dark from now on but, other than that, what can we do to protect him? Is it likely that he would be seriously injured or do most domestic cats manage to fight foxes off?
