What happens to animals once an experiment is completed?
The majority of research animals must be euthanized so researchers can study their tissues and answer important questions about disease. Animals involved in experiments that do not require tissue for study may take part in additional experiments. However, except in rare circumstances, federal regulations do not allow an animal to be used in more than one major surgical procedure.
