Don't know about the bedding, but damned sure odd they didn't eat at least the piglets. They are def cannabillistic. Learned that way back as a little kid when my GF raised hogs. Sows would eat their young down to one less than teats they had to nurse them. When a sow got to within two open teats, he would prowl, and as another one was dropped, he would deftly snatch one and move it to another sow with fewer piglets. He was one hellova hog farmer!
