Ivy League universities hype themselves as elite institutions with high research standards—so why do they all experiment on animals?
For decades, these universities have claimed they’re committed to reducing animal use, replacing animals with animal-free methods, and refining experiments on animals so they’re less cruel, something known as the 3Rs principle—all while quietly brain-damaging pigs, punching holes in rabbits’ jaws, and more. 😡 Here are just a few examples:
- Cornell University experimenters gave week-old female rats boob jobs by cutting open their backs before killing and dissecting them.
- Yale University experimenters irradiated pregnant monkeys and their developing babies, separated the two after birth, and subjected the babies to years of tests before killing them and cutting out their brains.
- Columbia University experimenters cut open pigs, removed their organs, and transplanted them into other pigs and baboons before killing the animals.

At Columbia University, intelligent, social baboons are confined to barren metal boxes barely larger than their bodies.
- Brown University experimenters cut into pigs’ chests, implanted posts onto monkeys’ skulls, and cut off baby rats’ testicles.
- Dartmouth College experimenters injected tumor cells into the heads of months-old pigs to cause brain cancer and injected chemicals into newborn rats’ brains to mimic schizophrenia.
- Harvard experimenters cut mice’s skin open, exposed their muscle, and froze it with a cold metal rod.
- Princeton University experimenters drilled holes and screwed implants into monkeys’ skulls, causing brain damage.
- University of Pennsylvania experimenters cut open pigs’ skulls, damaged their brains by jamming a rod into them, and killed them.
Experiments on animals are bad science and have no place at universities. Studies show that 90% of basic research, most of which involves animals, fails to lead to treatments for humans, while 95% of new drugs that test safe and effective in animals later fail in humans. 🤦
Please urge Ivy League universities to prove their commitment to the 3Rs principle and move toward compassionate and effective non-animal research!
