We're using more and more animals in labs every year - contrary to what the industry claims.
A new report that used data on the biomedical research industry found that since 1997, there has been a 72 percent increase in the number of animals used in federally funded labs.
Published in the Journal of Medical Ethics, the study found that the total number of lab animals spiked from 1,566,994 in 1997 to 2,705,772 in 2012. While the use of cats, dogs and primates generally stayed the same or decreased slightly, the dramatic spike was mainly caused by the use of mice, who are often used in genetic modification experiments. Mice are also not covered under the Animal Welfare Act, meaning scientists need to meet fewer regulations to test on them.
