A grim video shows lab monkeys being “driven mad” in tiny metal cages where the animals are allegedly kept for years at a time.
PETA, an animal rights group, shared the video after suing The University of Massachusetts–Amherst where some of the animals were caged.
Footage shows rhesus macaques spinning on the spot, stuck in repetitive patterns, pulling out their hair, rocking back and forth, and banging on the metal doors.
One monkey even pushes its fingers into the corners of its eyes.
In its press statement, PETA says: “Imprisonment in laboratories is so stressful that monkeys are driven mad, their immune systems are compromised, and data from any experiments done on them is virtually useless.
“Stripped of everything that makes life worth living, gentle monkeys are not ‘housed’ or even ‘caged’ in laboratories so much as they are stowed like luggage or stored as if they were merely beakers or test tubes.”
PETA said the experiments happened at four National Primate Research Centers – Oregon National Primate Research Center, Southwest National Primate Research Center, Washington National Primate Research Center, and New England National Primate Research Center – who were part-funded by the US government.
The video has been watched more than 5,000 times since it was uploaded on PETA’s YouTube channel, with many viewers saying it was distressing to watch.
One person commented: “I can’t bear to even watch this torture.
“In their eyes we humans are all monsters.”
“This is horrific these poor monkeys don’t deserve any of this I will try to do everything I can to help stop this,” said another upset viewer.
A third wrote: “They keep doing these experiments that don’t prove anything I think the scientists are just sadistic psychopaths.”
This comes after a group of villages hung a monkey to death from a tree while clapping and cheering after complaining that it was stealing their food.
And a monkey survived a liver transplant from a pig in a groundbreaking experimental surgery.
