On September 11, 2011 the worlds first glo-kitties were born. The cats genes were genetically modified with the fluorescent glowing genes found in jellyfish to make them glow. They're being used to study the AIDS virus and FIV (Feline Immunodeficiency Virus).
Eric Poeschla led the study in Rochester, Minn. His team is studying how the 2 viruses can be so tiny and still do so much harm.
Pros: more research on 2 deadly viruses, the cats look cool, we're learning more about the whole GMO ordeal, and saving the lives of many cats.
Cons: it's expensive, it's very controversial, the whole experiment could fail, and as of right now, we don't completely know what harm this could be causing.
Personally I think GMO's could be a good thing. We're doing research that we hope is beneficial to the lives of thousands of organisms out there so as long as it's being used for good then I think it's fine.
