‘Marmoset’ Victims to Protest Deadly UMass Monkey Experiments at Psychologists’ Conference

For Immediate Release:

Washington – While University of Massachusetts–Amherst (UMass) marmoset experimenter Agnès Lacreuse speaks at the American Psychological Association (APA) conference on Saturday, PETA “monkeys” holding giant photos of victims from her laboratory will clamor outside the convention and call for an end to the school’s cruel and deadly menopause experiments.

When:    Saturday, August 5, 2 p.m.

Where:    Outside the Walter E. Washington Convention Center, 801 Mt. Vernon Pl. N.W. (at the intersection with Seventh Street N.W.), Washington, D.C.

Lacreuse cuts into and screws electrodes onto monkeys’ skulls, cuts into their necks, deprives them of water, restrains them for hours at a time, and torments them in various other ways, purportedly to study menopause, which marmosets don’t even experience. To simulate menopause, Lacreuse cuts out their ovaries and uses hand warmers on their bodies to mimic hot flashes. She has squandered $5 million in taxpayer funds on this farce.

“Conference attendees should know that Lacreuse’s experiments bring shame to their organization,” says PETA Vice President Dr. Alka Chandna. “PETA urges members of the APA to be leaders in science and condemn the torment of monkeys at UMass.”

PETA—whose motto reads, in part, that “animals are not ours to experiment on”—opposes speciesism, a human-supremacist worldview.

“Almost all of us grew up eating meat, wearing leather, and going to circuses and zoos. We never considered the impact of these actions on the animals involved. For whatever reason, you are now asking the question: Why should animals have rights?” READ MORE
