Its acctually not that big a deal. Lions, despite how they may be shown on all the nature films while hunting are actually quite mellow creatures. The only time a lion is really agressive is when it is Hunting, under threat or defending young. Any other time they could really not give a rats ass. The Female lion is actually the agressive one when it comes to lions so i doubt that this would be able to be replicated on a female. All the males do is eat sleep and have sex really.
