0005674: Can prefer to eat non-butcherable vermin

Notes

(0021561) NW_Kohaku (reporter) 2012-03-18 13:53	That depends - are they capable of eating live vermin if they have a preference for them before running out of all other types of food? Are they preferring some sort of prepared vermin that is not possible to eat, like fly brains, because those vermin cannot be normally prepared? Those would be bugs. If someone prefers eating cave spiders, that should mean they will go out and eat a live cave spider whenever possible. And frankly, that sounds like something that should be REALLY rare and weird, if it ever occurs at all, and could still be considered a bug. Likewise, there is always the problem of dwarves preferring things they should never have come into contact with in the first place - why should dwarves prefer acorn flies if they've never been in a savage biome in their life, and never would have had the chance to encounter one? Do vermin fish get properly considered for preferences while other types of vermin you don't normally hunt, like worms, are not, by the way?
