Just to put this out there, I'm not into poop, and I do understand the kiddies might make a whole lot of fun of this. But - Scat tracking is a very viable way of finding prey. And as DayZ is going for an unprecedented level or realism, it just feels to me like a good fit. Finding rabid dog scat and hearing distant dogs barking would scare the hell out of me personally. Edit: A note on longevity. I know we are starving to death now after only a couple of hours of not eating (I guess we are not in good shape to start with). As for scat, I think it would be a rare thing to a starving person. Three meals to one time-sensitive, necessary emote is a good guess - Unless you eat bad food that is.
