Where do scientists get their laboratory animals?
The vast majority of laboratory animals are mice and rats that were bred specifically for research. Nearly half of the dogs and cats used in research were bred for that purpose as well. Animal dealers are the primary source for the rest. They must be licensed by the U.S. Department of Agriculture (USDA) and must adhere to Animal Welfare Act standards of care. Some research facilities do get dog and cats from shelters and pounds, but this is subject to much stricter regulation than it once was. In many cases, state laws and local policies prevent this. For a Humane Society (HSUS) statement against using animals from the pound for research purposes, go here. For the Foundation for Biomedical Research view of the pet theft issue, go here.
