NAVS: Taking Action for Animals

Vivisection (vi-və-ˈsek-shən)
n. The practice of cutting into or using invasive techniques on live animals. Derived from the Latin vivus, or alive, vivisection is commonly called animal experimentation, and includes the use of animals for research, testing and education.


Founded in 1929, the National Anti-Vivisection Society (NAVS) is a respected leader of advocates for animals and better, more humane science. NAVS has a proud history of promoting positive solutions to replace cruel, costly and flawed animal experiments with modern, innovative methods of research, safety testing and education.

NAVS works with scientists from academia, government and industry to develop and implement smarter, human-relevant research methods that replace the use of animals through funding of the International Foundation for Ethical Research (IFER) and other promising collaborations with the scientific community.

NAVS supports integrating today’s technology into science classrooms to make the life sciences more exciting as well as more humane by providing safer, cost-effective educational resources to replace animal dissection. By recognizing humane science achievements at science fairs, NAVS is providing positive incentives for future generations of researchers to advance science without harming animals.

NAVS empowers individuals to make a positive difference by providing timely information on pending legislation and ways animals are used in science so they can easily take action, spread the word, and make informed, compassionate choices.

NAVS’ Sanctuary Fund advances greater compassion for animals by providing emergency financial assistance to support animals retired from laboratories and those threatened by natural and man-made disasters.
