I just was watching one a couple of hrs. ago, and they rescued well over 200 cats out of a cat collectors house.... The man actually lived inside the house in there, when all the people rescuing them was about to pass out from the smell....not to mention all the feces all over the walls, caked on the floor, and etc.
Unfortunately all of the cats were very feral and aggressive and had to be put down...
That's one of the worst ones I've ever seen.
