I really like the ideas c:
But one thing about the dragging food part.
From what I know, wolves (not sure about lions) do not drag their food back. They sometimes bury food in random places to come back to for later but do not bring the rest of the prey with them. They only take what their tummies can hold.
Anyways, this is just me ranting. c: It would be a good idea, but just not as realistic, you see?
Overall I'm liking the way you think, though. C;
