My mother has an ostomy. I realize that the procedure was done to save her life, which is dfferent from the situation with the cows. However, the ostomy does not hurt, nor is it cruel.

So that is not the reason I would be against this. There is no cruelty here in my mind since there should be no pain.

The reason I am against this is because we should not be testing on animals, period. The same as we should not be testing on humans.
