Drama at the fence

Last night while we were having our braai we heard a commotion at the fence, the Hyaenas were making a lot of noise, through the spot lights we saw the Hyaena feeding on something quite large, shortly after we heard some loud growls. What had happened is that a Leopard had made a kill and was dragging the kill to the nearest tree when the fence Hyaenas came across the Leopard and robbed him of his kill, we heard the Leopard growl several times. We could not identify what the kill was and in the morning there was nothing left.
