I'm surprised too. Animal research is the modern "food chain" with us humans using animals to prolong our lives. Food prolongs our lives, so does medical research.
Which doesn't mean that animals should be subjected to torturous testing without the use of pain reducing drugs. I'd be dead right now if they hadn't been able to test heart stents on pigs, etc. As for doing it on death row inmates, sure, that happens now. There aren't enough of those men willing to be test subjects to continue research.
So, I believe that animal testing is an OK thing, when properly monitored.
