No they aren't. What's that have to do with anything?
A human can eat any animal. A human can't eat any vegetation. What point are you trying to make exactly?
That people don't kill wolves to eat them. So it makes no sense to compare killing wolves for sport to killing livestock.
The semantics is strong with this one. Livestock is a word, it doesn't change what it is. Killing for sport, population control, or any other reason is hunting.
