Join the fight to end cruelty to animalsThousands of animals are suffering right now in unreliable tests that we believe are unnecessary

Every year, hundreds of thousands of animals endure the horrors of what we believe are unnecessary 'second species' testing, and evidence shows much of it is completely pointless.

When initial tests on smaller animals like mice or rats don't produce enough evidence to guarantee safety in humans, other species like rabbits, dogs or primates, are made to suffer through the same tests. And not only that – it’s dangerous to humans too because the data it produces is unreliable.

With your support, we can end this cruelty. Your donation can help us get existing evidence in front of the right people, extend our own research even further, and rally more support against this cruelty. Together we can end second species testing.

Will you help us end this suffering today?
