AFI frontman Davey Havok has partnered with People for the Ethical Treatment of Animals (PETA) for a new ad, in which he speaks out against animal testing.“In animal testing that still occurs today, millions and millions of rats and rodents are destroyed for no good reason whatsoever,” Havok says during a video posted on World Rat Day (April 4).With a rescued rat named Wee Man resting on his shoulder, Havok specifically targets a rodent behavioural experiment called “the forced swim test”. Also known as “the despair test”, it is typically used for the evaluation of antidepressant drugs.“They take a little guy like Wee Man and they throw him in water to measure depression,” Havok explains during the ad.
