I just think that in a addition to how amazing this game is, I feel it might be missing the interaction side of the social unit that is a pride. I would love to see a section (maybe called "The Pride") where players can see the whole pride together and interact with the individuals, including the cubs.
This is could also contribute to the mood of lionesses. This should also change when lionesses are out on hunts and sub males are out patrolling, so you can't see them when you click on the pride section. Maybe these pride members could be in front of the den. (players can choose between a selection of dens and customise these dens with trees, bushes etc.

Oh and before I forget, maybe more of a selection of lion pictures. ( for lions, lionesses, cubs and adolescents)

So yeah this is my idea, hope everyone can support !! :)
