Founded 1875, the National Anti-Vivisection Society (NAVS) is the world’s premier society working to end the suffering of animals in laboratories.

We educate and promote the replacement of animal experiments with sophisticated, non-animal methods. NAVS studies include legal and scientific research and critiques, investigations of laboratory practices, reports, videos.

NAVS supports the replacement of animals with advanced, non-animal, scientific and medical research.

Every year millions of animals suffer and die in cruel and unreliable experiments.

Please consider remembering the NAVS in your Will to end the suffering, and press for introduction of advanced techniques, relevant to people. Thank you.
