Noneking how big is that property and how many animals? Guess they would have to remove some in the future as I see no big cats? 
Normally owners are not allowed to have dogs in a development like that. Apparantly scares the animals.
Not sure of the total size, but has to be a few hundred hectares. There are about 50 stands of roughly 2 hectares each and then also some open common property and dams. Pets have to be kept behind electric fence. Dogs get used to game fairly quickly.
Kudu, Nyala, Waterbuck, Zebra, Giraffe, Impala, Duiker etc on the property
Game caught and sold when necessary - keeps levy low compared to other estates in area
