Vielleicht kommst du weiter, wenn du dir das Plugin "Passive Healthy Wildlife" besorgst und im CS schaust, was der Autor gemacht hat.

Auszug aus der README:

This mod changes the attack setting of MOST non-diseased animals into a
much more PASSIVE state in which they DO NOT attack unless attacked first or "bothered."

This mod is different from other animal pacifying mods in that the healthy animals WILL
attack if you "bother" them. In other words - come up to them for too long and they will attack you.
