For decades, countless cats have been imprisoned, cut into, and killed in cruel and useless "sound localization" experiments at the University of Wisconsin–Madison (UW).
The response from UW:
Allegations made today (Wednesday, Sept. 12) by People for the Ethical Treatment of Animals about sound localization studies at the University of Wisconsin-Madison are unsubstantiated. At best, they are a gross misrepresentation of the research and the care and treatment provided to the animals in the study.
In case you were wondering. For me, PETA's done enough harm to their own credibility that I immediately and almost uniformly discount their claims as soon as I see their logo.
