A bizarre video has emerged from Kruger National Park in South Africa of lions mating while killing a warthog.<br /><br />In the clip, which was filmed last month, the lioness has the warthog by the jugular when the male approaches and they begin to mate.<br /><br />Lions in the Kruger National Park are at times very active sexually, mating every 15 minutes for up to five days. However seeing them mate while a kill is in progress is extremely rare
