Advancing Science without Harming Animals
The National Anti-Vivisection Society (NAVS) is dedicated to ending the exploitation of animals used in science.
One Purpose, Many Paths
Is it possible to stop animal experimentation and the use of animals in research and education? Absolutely yes. Momentum is shifting away from flawed assumptions, making way for more innovative and effective models and methodologies.
Advancing Humane Science
We are against animal experimentation and for relevant and effective testing protocols.
Ending Classroom Dissections
We promote the latest innovations in anatomical modeling for richer learning experiences.
Supporting Sanctuaries
We bring hope and peace to animals who have been cruelly subjected to experimentation.
Advocating for Policy Change
We drive legislation to stop the exploitation of animals in the name of science.
