The HSUS recognizes that: (a) animal research has produced data that have led to advances in biological knowledge and medical practice; (b) scientists and animal care staff are concerned about laboratory animal distress and death; and (c) like The HSUS, most scientists would prefer not to use animals in harmful procedures to develop new knowledge. In light of these considerations, The HSUS campaigns for: (a) the development and use of alternatives; (b) the elimination of laboratory animal pain and distress as a priority; and (c) an open dialogue and, when appropriate, joint action, among scientists, animal protectionists, regulators, educators, and other interested parties, to tackle the ethical and practical issues concerning laboratory animal welfare.
