I've heard, seen and read about cock fighting. It is absolutely illegal here in the UK and thank goodness for that.  Frankly speaking, its babaric IMO, pitting helpless cocks against each other all for the cheap fun of some.  I'm totally against any/all kinds of animal fight games for the fun of humans.  To me, its the same or at least similar category as those who kill animals (GAME) for the fun of it.
