Donate now to protect animals from suffering in laboratories and from all forms of cruelty.

Every year, more than 100 million dogs, monkeys, rabbits, mice, and other animals undergo painful procedures in research and testing laboratories around the world. Their entire lives are spent in confinement, and they suffer tremendously. HSI is at the forefront of global efforts to end cruel, outdated and unnecessary animal tests—for good.

Your donation helps make our lifesaving work possible. Along with helping animals confined in labs, your support also helps protect all animals—including street dogs, those on factory farms and those abused in the wild.

You can help stop this cruelty. Please give today.
