Each center breeds and experiments on thousands of monkeys, mostly macaques. You’ve likely seen the images of monkeys warehoused in small, barren stainless steel cages for experiments that can last months or even years.
Monkeys confined at NPRCs have been deprived of companionship—and knowing who their friends are and whom they can look to for support is of the utmost importance to monkeys, as is the opportunity to make decisions for themselves. They have no control over their lives, and they don’t get to raise the babies they’re forcibly bred to have.
While a couple of the NPRCs have outdoor spaces where “breeders” are kept, the babies and juveniles are removed from their mothers within the first year, causing unbearable anguish. The continual movement of monkeys in and out of these laboratory breeding corrals often leads to horrific injuries and even infant deaths. Once removed, the young monkeys are used in experiments that are invasive, painful, distressing, and very often deadly.
