Animal Sacrifices or Something the Cat Dragged in?

A new study of burial cairns and brochs has led researchers to question whether animal remains found at the sites were offerings to the dead or merely "something the cat dragged in."

Emma Sanderson, of Caithness (Scotland) Archaeology Trust, found rabbit remains left by a cat in the replica of a burial cairn causing her to question earlier theories. Experts are also looking at previous theories about whether cairn openings were ceremonially closed or merely fell down with time.
