There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.
To be honest, I think the whole male cubkilling thing is more based on learned pragmatism than an actual instinct or anything like that to bring the lionesses into esterus.
They are only a small group so food likely isnt much of an issue and the subadults are female so they are more potential mating oportunities than direct rivals.
