Dear Editor: After seeing PETA?s photos of cats being experimented on at UW-Madison, with steel coils in their heads and other extreme cruelty, I organized a petition to have these experiments stopped. So far it has been signed by people from all over the USA and the world, from Brazil and Australia to Greece and France. I hope others will support this petition and end this totally unacceptable torture of cats. Universities should be places of advancement and non-animal research.
