Animal testing has also been traditionally used to test pharmaceuticals that aren't yet known to be safe for humans. Many life-saving inventions have reached the public through approvals and 'comfort levels' garnered from the results of animal testing.

I like animals. A lot. I live with two of them and my parents have my cat. However, I also would just once like those folks that advocate the boycotting of products tested on animals to also apply this criteria to medicines created this way as well. And no, I don't stand to profit in any way from these...except, maybe, to live longer and in less pain.
