We had a feral cat at Gib when I was there in the early 80s. His name was "Nelson" - cos he only had one eye. Only the brave ever tried to feed Nelson because if he saw you with food, he would attack at once and was completely fearless. Such a good mouser was he that even the rats would not come out in day light. Having tried to make friends and had my right arm savaged more than once by Nelson, I decided to put him on a starvation diet for 48 hours to teach the bugger a lesson. So fearless was he that I saw him attack a Herring Gull bigger than him, only to be attacked by two others, despite being badly wounded, Nelson killed all three of them, dragging the biggest home for dinner. Dat's my boy!
