How can I stop nauseous animals from vomiting everywhere?

Solution 1:

If you just want to fix it (i.e., remove all the piles of vomit) you can download DFHack and use the "clean" subprogram to remove all contaminants on the map. Works on blood, dye, snow, vomit, and ichor, I think.

If you do that and your animals remain nauseous, you might have some underlying cause.

Solution 2:

I asked it on the bay12 forums here. I think Sphalerite was right about it being that FB's dust. (I can see Raven was thinking something like that too.) Every one of the nauseous animals just suffocated, almost simultaneously...I hope I can build 50 coffins fast, and keep a mega tantrum spiral from happening. O.O

EDIT: Oh, no it's starting! My legendary dining room better work it's magic!
