God bless those people for what they did. Unfortunately, after the experience they've had, some of those cats will have to be euthanized. They will likely never be suitable for adoption.
I sure hope I'm wrong.
A couple years ago I saw a video and pictures of live DOGS in a Korean market. Dozens if not hundreds of dogs, mostly small ones jammed into wire cages.
Dog meat in Korea, apparently like cat meat in China, is a delicacy. And the preferred prep method: {{STOP READING NOW IF YOU HAVE A WEAK STOMACH}}
They use a blow torch and cook them
ALIVE. 
Apparently the fear and pain create adrenalin and other body chems that tenderize and "sweeten" the meat. I still have nightmares over this one.
This is the kind of crap that has to be STOPPED. We don't even inflict this kind of cruelty on vicious murderers and child molesters.
