Center for Alternatives to Animal Testing

The Johns Hopkins University Center for Alternatives to animal testing (CAAT ) has worked with scientists since 1981 to find new methods to replace the use of laboratory animals in experiments, reduce the number of animals tested, and improve the necessary tests to eliminate pain and anxiety. CAAT is an academic, science-based center affiliated to the Johns Hopkins Bloomberg School of Public Health.

CAAT promotes human sciences by supporting the creation, development, validation, and use of alternatives to animal testing, product testing and training. It is not an activist group; rather, want to effect change by working with scientists in industry, government and academia to find new ways to replace animals with animal experiments, reduce the number of animals required, or refine methods to make them less painful or stressful for the animals involved.

CAAT also operates Altweb, a global clearinghouse for information on alternatives to animal testing, and publishes a general animal news blog, a boundless ethics.
