Yes, there is. But that's not the point here - when you slaughter animals professionally and according to civilized standards, you reduce their suffering to an acceptable minimum. On TV, I saw how this festival is "celebrated" in Libya. A father with his son buy a sheep. It's legs are tied so it can't walk, and they load it on a wheelbarrow as if it was a sack of grain. They take it home, where they slit its throat and leave it to bleed to death. Very civilized - if kids see that all the time, no wonder they grow up desensitized to killing.
