The Johns Hopkins Center for Alternatives to Animal Testing (CAAT) is a small, non-profit center. As part of the Johns Hopkins Bloomberg School of Public Health, CAAT is dedicated to improve the health of both people and animals.

CAAT's mission is to promote humane science by supporting the creation, development, validation, and use of alternatives to animals in research, product safety testing, and education. They seek to effect change by working with scientists in industry, government, and academia to find new ways to replace animals with non-animal methods, reduce the numbers of animals necessary, or refine methods to make them less painful or stressful to the animals involved.

CAAT also has a website, Altweb (the Alternatives to Animal Testing Web Site) devoted to 3Rs and alternatives news and information. Altweb is the U.S. home of the journal ALTEX: Alternatives to Animal Experimentation, which is the official publication of CAAT.
