A goat ate a full pack of Camel filters I left on some blocks while I climbed up to help put a roof on a garage. Tobacco, filters, package, foil, ... everything. I freaked out and told the guy who owned the goat, thinking I might have killed it for him. He just laughed and said "sorry about your cigarettes but they won't hurt my goat. He'll eat anything."
Now that I think about it I should have charged him for worming his goat! ;^)
Sheep are always just looking for a place to die. Not very hardy creatures.
