PU leather, aka Bycast Leather, is Reconstituted Leather (small leather scraps) or Bonded Leather that is layered with thick Polyurethane to give it a sheen like real leather. The image of such a process that comes to my mind is like gluing scraps of wood together and pack it really tight to look & feel like real wood. Since it is synthetic material, it doesn't last as long as real leather. However, for a handbag, I personally think it is ok to use. For shoes, I wouldn't recommend it though, as shoes tend to wear out faster and Polyurethane is not a breathable material like leather. As for sheep skin....well, within the accessories industry (bags, belts, shoes, planners, etc), they classify any animal skin (cow, calf, lamb, sheep, even pig) as "leather."
