Mice are intensely social animals who love to play together and curl up next to each other at night. They even sing to their friends at frequencies humans can't hear.

They're also among the most abused animals on Earth, and despite the current historic public health crisis, the National Institutes of Health (NIH) is pouring tens of millions in taxpayer dollars into crude and cruel experiments on them.

For six months, a PETA investigator went undercover at the Cleveland Clinic—an institution that received more than $100 million from NIH in 2019 alone. Inside the clinic's laboratories, they found that experimenters injected mice with a chemical that caused an inflammatory disease of the central nervous system, leaving them struggling to walk and dragging their hind legs. In addition to gluing glass plates onto the skulls of mice, workers cut into other mice's backs and separated their muscles from their vertebrae in order to take pictures of their spinal cords.

To give you some idea of how little concern experimenters had for the animals, when veterinary technicians told one experimenter that mice used in a kidney disease experiment were in pain, the experimenter apparently replied that they wanted to "kill" the mice "just because they're ugly."

And it's not just mice who are suffering at the facility—monkeys, rabbits, rats, pigs, and other animals are being routinely experimented on there, too. No animal—no matter their size—should ever have to experience such abuse.

Please donate right now to power our vital work to expose—and stop—cruel and deadly experiments and promote modern test methods that save lives.

Today, we're ramping up pressure on NIH to stop wasting billions of U.S. taxpayer dollars on experiments on animals like those at the Cleveland Clinic—experiments whose failure to provide human-relevant results even the agency itself acknowledges.

The innovative work of PETA scientists is helping more and more researchers around the world embrace sophisticated, non-animal methods, like the team of engineers and physicians in Bolivia who—with our guidance—recently developed a lifesaving new ventilator for COVID-19 patients without testing it on animals. NIH has now begun an investigation based on our findings at the Cleveland Clinic, and already tens of thousands of our supporters have joined our call for the agency to stop funding such hellish experiments on animals.

But as long as sensitive animals are still being tormented in laboratories like the ones revealed in our new investigation, we must do more. Are you with us?

For the mice like Daisy, there's simply no time left to lose.
