I disagree, experimenting on animals is not the only way to find cures, test drugs or chemicals. The caregiver is the one that tends to the animals, he is the one that sees the pain and suffering. But he/she is only a caregiver and is either too emotional or too stupid. The researcher can not say how the animal feels, they can't talk, often animals suffer in silence, or some of them whimper.
The next decade will be exciting, several countries are not going to use chimpanzees any more. It will be interesting what happens from here.
There were quite a few GREAT scientists that did not approve of vivisection...., their career never suffered, nor their new discoveries.
