Behavior
Maybe you have noticed how each animal mentioned does not usually exhibit violent behaviors. That is to say these do not kick and maul each other in mating or in food as some others are wont. In all the animal kingdom there are a wide range of behaviors. For instance, a certain bird is well-known for eating or pushing the eggs out of other smaller bird's nests. Then in their place she lays her own. The unsuspecting mother bird then hatches and cares for these unusually large chicks as though they were her own. Then one day the chick that wasn't hers is all grown up and the cycle repeats itself. While the elephant, zebra, and giraffe inhabit grasslands, they prefer to live as nomads always on the run from danger or in search of greener pastures. You could almost say these are driven by a need to wander. That's to say nothing of the cats of course.
The Lord almost loves them, those little miniature versions of a house lion. But sometimes they be outside fighting tooth and nail while making the most hideous wailing. It can be over something silly too like the mouse that got away, the new cat on the block, because they looked at each other funny, felt threatened, or whatever. Seriously though, it's usually all for food, territory, and for funding a mate. Polar bears which live in the Artic are known to fight for territory and over any left-over food or for any reason at all really. Their small cousin, the brown or black bears prefer instead to forage for their food attacking only with their cubs nearby or when threatened. Monkeys too might look cute and innocent at first. Soon however, the air is filled with all sorts of chatter which sometimes gives way to loud arguments.
At these moments, all the animals converge in a troop and mimic the leader, who is usually unjust to its' other members in the troop. It's a real shame too because they almost could be representatives of animals forming a higher social order. Due to their frequent fighting and squabbles over next to nothing, they are not representatives of anything higher much less a social one at that. This in the event of a cataclysmic event their survival is not determined. Such an event was once faced by the dinosaurs with crippling effects. When was the last time you saw a dinosaur walking around outside of myth or legend?
And an highway shall be there, and a way, and it shall be called The way of holiness; the unclean shall not pass over it; but it shall be for those: the wayfaring men, though fools, shall not err
lion shall be there, nor any ravenous beast shall go up thereon, it shall not be found there; but the redeemed shall walk there:
Isaiah 35:8-9
