So what are this kid's thoughts? I haven't looked at too many demon resumes lately.
Babies eat from their mommy's breast. Actually, I suspect they simply don't eat at all, but I'm not sure. I'm pretty sure they don't eat normal food, though. I suspect if it did transform, it would happily eat from the community stocks. Or rather, just from the community.
Yes, an unconscious dwarf in a tile with a cage trap gets caught. Handy at times, annoying at others. To get it out you need to build the cage (b->j, select location, then hit x to select the specific cage with the dwarf), then link it to a lever and pull the lever. The dwarf, cage, and one mechanism all pop loose. To recover the other mechanism you have to deconstruct the lever.
No, getting bit won't always result in a knockout. But if the were keeps biting and shaking the dwarf, it will probably give in to the pain and get caged eventually. But it could still bleed to death in the cage before you can get it out, especially if the were rips any limbs off. Of course, the were could bite him on the head and shake, ripping the head off, helm or no helm. As Quartz_Mace said, there is a certain amount of risk to this process. Expect to lose a few. Just keep reminding yourself what Stalin said about eggs and omelettes.
But any that survive until the next full moon will have those missing limbs restored. \o/
