Why are there no Hyenas in any of the zoo's?++++++++++++++++++++++++…

Zoos kept them predominantly for educational reasons, in particular because of their role in the food chain and their interesting social behaviour. However, the number of zoos keeping this species is relatively low, as zoos tend to focus rather on the African wild dog, which has a similar distribution, plays a similar ecological role and is also organized in packs, but which, differently from the hyena, is Endangered in the wild .
