This reminds me of a story I heard a few years ago about some animal rights activists opening the cages at a slaughterhouse and getting trampled to death by the pigs.

Anyway, as far as necessary research goes, I'd rather it be done on humans who've given consent. They're a far better indicator of human reactions and stuff, given the fact that they are humans.

However, I find animals rather tasty, so, I guess PETA still hates me.
