From what I heard about KC (the author) is that Mamono are willing to indulge in almost any fetish (though probably depending on species), as long as that fetish is not "guro". Which mostly means gore and mutilation fetishes.

While I'm not sure what KC himself counts as guro, the setting makes it clear that, as long as nobody is truly hurt in any way, the setting allows for it. Though I'm not sure if scat or fart or pee fetishes are honestly considered very appealing to them, even if Mamono have no moral objections to it.

And I think that things like vore might be allowed, as long as it remains non-lethal. And, depending on the kind of vore, if the body isn't horribly deformed.
