I don’t really think the rabbits would have Nature. They aren’t “still only mice (in this case rabbits)” like MG. They are rational, emotional, and organized, whereas the people are monsters and cruel abominations that gas and imprison their friends. Its a constant battle, but you never see the rabbits revert to being, well, rabbits.
But hey, I’m just glad somebody recognized what I was talking about. If I have to add nature, so be it.
I’d say the rabbits are as much rabbits as the mice are mice. They’re not real-world rabbits, obviously; they speak, they think, they organize. But they’re rabbits all the same.
