I had the same reaction as you but apparently here is the explanation about all these stuffed animals, my good friend Jay, explained it to me:

“They need to cull the animals in game reserves to prevent over population and depletion of natural food sources. You need a permit to hunt and you can only hunt what your permit allows.
Only 1 animal at a time. If you don’t find one, sorry ka nalang. When they kill an animal like zebra, kudu or oryx, nothing goes to waste. They eat the meat, use the skin, horns, etc.”
