Have you been with D and Y Fox? They seem to be well regarded here.Definitely in Namibia, but I think the continent might be a stretch. Zambezi valley areas, Niassa, Southern Tanzania all have extremely high success rates on cats. A Namibian leopard might be much larger on average, but also much more educated by farmers and a lot more likely to be taken a night as opposed to daylight hours. I think it’s difficult to compare a Namibian Leopard hunt to Zimbabwe. They are two very different hunts.
Also, if going on first leopard hunt, would you recommend one of the cat specialist outfits?
