The Large Grey Mongoose was kept as a pet in ancient Egypt to control rodent and snake numbers. Snakes do not form a major part of their diet, but they do kill and eat them when the opportunity arises. Their size, long fur and a resilience against snake venom makes the whole business a little saver for the mongoose.
They are mostly diurnal and prey largely on small mammals. They prefer well watered areas close to rivers, streams, ponds, etc.
Now, some of you might be thinking: "Wait! I've seen this mongoose on this blog before... It's clearly a Small Grey Mongoose!". Well, to that I would reply: "Aha, but look at the tail, especially the point...".
I was starting to think that I might be nearing the end of the mammal diversity at Tygerberg, but there might still be 2 or 3 species out there to find. I also still want to try for shrews sometime soon :)
