A whistleblower at Shin Nippon Biomedical Laboratories (SNBL), an animal testing conglomerate, got in touch with PETA and brought them undercover video of the horrible cruelty and mistreatment of monkeys at the testing lab.
The monkeys live almost their entire lives in fear and pain until they are killed through the course of experiments.
Check out the above video taken from inside the lab of the poor test monkeys.
It is comforting to know that at least someone in the lab had the heart to risk their job for the suffering animals.
