In Minecraft, yes, you can feed sheep. Sheep can be fed wheat. When you feed a sheep some wheat, it becomes happy with you and has love heats floating around its head for a while. If you feed wheat to two sheep and bring them together, they will kiss for a few seconds, then a baby sheep will appear. This is breeding. Alternatively, if you hold wheat in your hand without feeding it to a sheep, the sheep will follow you. This is useful for herding sheep into a fenced farm. See the link in the related links below for more information.
