Eleanor Holmes answered on 13 Nov 2013:

I don’t do tests on animals so I do not know the procedure. However I am informed that any labs that carry out tests on animal subjects are held to extremely strict standards. Labs are better regulated than farms or even some zoos.

The majority of animal testing in science is carried out in Universities. These animals are taking part in serious, scientific research as opposed to product testing or other commercial pursuits.
