Eiro stood in the cave and proceeded to cut the boars' corpses up into the different parts properly. Of course, mainly he wanted to cut the meat off of the bones so that he could prepare it well, although there were some parts that were better when the bone was still attached.
When it came to the cuts that were meant for the children, however, Eiro made sure to remove all of the bones. Sure, they would probably be able to simply crush the bones into pieces, but it should be more pleasant for them this way.
