Animal testing and research
We're working around the globe to replace cruel, outdated animal experiments with innovative non-animal methods.
Taking suffering out of science
Animals don’t deserve to be used in experiments. Animal testing is a practice that belongs in the past. It’s time to prioritize animal testing alternatives that are safer, faster, and more reliable for humans—without causing animals to suffer.
90%
of drugs tested on animals
ultimately fail in human trials, according to the National Institutes of Health.
190
million animals
are estimated to be used in harmful experiments each year globally.
45
countries
have enacted full or partial bans on cosmetics animal testing.
The problem with animal testing
Millions of animals, including dogs, monkeys, rabbits, and mice, endure invasive and painful experiments every year. These procedures often occur without adequate pain relief and rarely predict how humans will respond to drugs or chemicals. Existing laws offer minimal protection for animals in laboratories.

Our global efforts to end animal testing
We’re leading efforts worldwide to promote humane research alternatives and eliminate animal testing.
Recently, Al and nine other chimpanzees were relocated from a New Mexico lab to the safety of Chimp Haven sanctuary.
By developing and integrating animal-free research methods, we’re helping scientists address major health challenges without harming animals.
We lead the Animal-Free Safety Assessment Collaboration (AFSA), a multi-sector initiative working to make animal-free safety science the global standard.
In a landmark case, Inotiv was fined over $35 million, the largest Animal Welfare Act fine in history, for violations at a Virginia facility that bred dogs for experiments.

Over 40,000 dogs are used in experiments annually in the U.S., enduring painful procedures and often resulting in euthanasia. Learn what happens and how you can help end this injustice.
Get the facts about cosmetics testing on animals and our fight to end this cruel and unnecessary practice worldwide.
Animal-free alternatives will one day completely replace experiments on animals—a game changer not just for animals, but for human health.
“Save Ralph” combines empathetic storytelling with the magic of stop-motion animation and performances by an A-list multinational cast as part of our global campaign to outlaw cosmetic animal testing.
We care for more than 60 chimpanzees at our sanctuary in Liberia. Most of the chimps at the sanctuary were used in invasive biomedical research, many of them for decades.

Help save more animals like Al
Al, a 51-year old chimpanzee previously used in biomedical research, sees his new sanctuary home for the first time. This is just one victory but so many dogs, monkeys, rats, and other animals are still suffering in labs. Act now and together, we can continue to help save animals from a horrific fate.
What I saw working in a monkey research facility
Kathleen Conlee recalls her past, working in a monkey research facility. The experience was only the beginning of her work with animals, and led to her leading the fight to alleviate and end the suffering of animals in laboratories. Hear her story.
