Ive asked before but no one aswered, scat and that kind of things are avoidable?
Yes, scat and urine are off by default.
Kinda are and kinda aren't.You can turn it off in the game menu
Even with those two turned off, if you get Lona's orifices stretched out enough, you still get pee & poo counters in the corner, get the "events" that say filth is dripping and have all relevant descriptions. It's just the actual counters don't progress, so you don't actually see any pee and poo.
Also, I have no idea when or how, but you may still find yourself, after some time, with stats like "pee in vagina" or "pee in anus" even with the option off.
Personally I F10 cheated max values of anal_damage and urinary_damage below the threshold, so those states won't trigger, but hardly an elegant solution.
