Also, it is confirmed (somewhere) that animals will fight and such, have wounds, after wounds heal then they will have scars.
So i am assuming and have high hopes that you can have a scenario like a wildlife park and the predators and prey roaming together and the preds would hunt prey as they would in the wild when need be (not for sport unless it has exhibited this behavior in the wild).
Random thought... - I wonder if you have new cubs in a pride and if you introduce a new male lion, (that beats the old male lion for his position), into it if he would kill the cubs as he would in the wild (same with dominant male zebras) as to start a family tree of his own? I surely hope we get that stuff because it is very important to know these kinds of things, although terrible, it is educational and would be detrimental to the conservation program in the zoo so you would think twice before you placed a new lion or other male animal into the exhibit if you had small cubs, foals, etc.
