I hunted in Namibia in 1993 with a buddy. We where there to hunt plains game animals, but if a Leopard showed up, we where more then happy to try for it. On a neighboring ranch, a leopard had killed a calf and dragged it into a dry creekbed. He had only ate a little bit of it, so we knew he would be back. We cleared a trail, built a blind and came back an hour before daylight the next morning. We got into position to watch for him, but didn't see him. One of the native trackers pointed behind us and there, laying low, under some brush was the leopard. He was about 20 feet away, just laying there, watching us. As luck would have it, I had second shot. As my buddy aimed at him, he growled at us. It was unreal how deep the sound was. Every hair stood up on the back of my neck and the sound of his growl felt like hot air hitting my face when walking outdoors on a hot day. He shot, it died and that was all it took. We figured that he was laying there when we walked by him in the dark, but nobody had a clue. Luckily the tracker looked behind us and spotted him. He blended into the rocky ground and dried bushes very well. We got lucky, it could have gone bad, or he could have just walked away and we would have never known.
