The Johns Hopkins 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 refine necessary tests to eliminate pain and distress.

We are an academic, science-based center affiliated with the Johns Hopkins University Bloomberg School of Public Health. We believe the best science is humane science. Our programs seek to provide a better, safer, more humane future for people and animals.

We provide a variety of resources, including grants for scientists developing non-animal methods workshops on alternative methods, books, newsletters, and other publications.

We also manage Altweb, an international online clearinghouse of alternatives news and resources. (read less)
