This would make it impossible to carry out any research. Criminal charges can be laid for contravention. Most medical research does not result in pain or significant distress to the animals. An example of such research is the study of pain itself. As a rule, valid and useful scientific findings are obtainable only when research animals are healthy and protected from undue stress.
Responsible researchers are concerned about the condition of the laboratory animals they study.
Such concern arises from both humane and scientific considerations. Good science and good animal care are inseparable. Scientists cannot afford to mistreat research animals, and accusations of animal abuse are rarely substantiated by the facts. To be a good research subject, the animal must be adequately fed and housed and kept free of any disease other than the one that may be under investigation. Poor care and treatment will reduce the reliability of the results of the study, something researchers must prevent.
