Matetsi, Zimbabwe, 2010. I shot a good sized tom from about 60 yards just before last light. Fell from the tree like a sack of potatoes. We waited for the truck, got some lights and a shotgun, had a brief discussion about not shooting each other, and then began to walk slowly towards the tree, flashlights on. Pitch black by now. Two Zim PH's (one a friend) - one with a .458, me with a .375 and the other with the 12 gauge semi with 00 buckshot. We expected to see the leopard at the bottom of the tree. Once we could see the base of the tree - about 7 yards away from us - no leopard. I recall saying "what now" and at that instant the leopard came at us from a gully about 10 feet in front of us. Shotgun was emptied - no time for any other shots. Dirt, dust and powder everywhere. The leopard ran into a bush about 12 yards away.
That led to a discussion about coming back in the morning, but could hear hyenas not far away. I was worried about finding nothing left of my trophy (second attempt at leopard). We discussed leaving the trackers there with a fire for the night, but that didn't seem fair. PH decided to give it one last try - throw something in the bush and see if we can get him out. Some rocks, then a large piece of wood, and out he came, once again at full speed and full roar. This time the shotgun got him, I got him, and the .458 got him.
Next morning, after the skin came off, we could see that it was shredded by the shotgun. He had also lost an eye - couldn't tell which time. No matter. I have no doubt that if he had gotten one of us, he would have done some serious damage either time. My first shot would have killed him if we'd left him a bit longer - well placed but inadequate penetration from a lousy bullet.
However you look at it, a seriously wounded cat came at us twice with the strength and more important the will to do us some real damage.
I would never underestimate a wounded leopard.
