I know exactly how you feel, I went in and removed over 175 cats and kittens from a cat collector's house and the smell was sickening and it was dark and all the animals were silver or black or Siamese and very few were altered, but I had to remain calm to get all the cats out before the county stepped in to euthanize them. It is sickness with some people. keep up the good work the kitty's need you.
