In my headcanon, fluffies are generally stupid, but not suicidally so. They have low level problem solving skills, and understand basic cause and effect, but only to a certain point. Math wise, most can only count to four (number of legs) but can go to twenty if especially smart. Ferals will understand the need to stockpile and ration food, but that is a learned behavior. They can learn, but only to an extent.
Reasonable sorry sticking (foam/padding covered wooden stick, or full wooden for severe offenses), and sorry boxing, plus as much psychological abuse as you want. A full force hit from an average adult will shatter bone. If you deal enough damage, they will no longer think of you as a human, but consider you a monster wearing a human face, due to being incapable of seeing humans as evil. If you leave for a while and come back you can trick them into thinking you are not the same âmonsterâ who hurt them.
Fluffies recognize danger pretty well, as long as theyâve seen something cause pain they will avoid it. If they see road killed fluffies, they will not cross a road. They recognize temperatures as dangerous (I.e. extreme hot and cold) as well as lack of resources (they wonât willingly live in a place lacking food and water). Ferals are the accumulation of knowledge from watching dozens of other fluffies die, eventually learning how to survive. In a herd, if a fluffy dies from something the herd will take action to prevent that from happening to another fluffy (leaving if there are dangerous animals in an area, teaching not to eat poisonous berries, etc)
Wan die just involves them completely giving up. They will not move, drink, eat, or attempt to avoid anything. They will only repeat âwan dieâ. They wonât move to attempt suicide.
Toughies can be stripped of their position by the smarty, the smarty can only be stripped of their position by total herd collapse due to incompetence (their actions get more than half the herd killed) aging out, or being excessively cruel. Neither go chirpy or wan die, they will either accept it and sulk or throw a tantrum and become violent, either of which will be dealt with by the new smarty or the rebelling herd.
