I do not support animal testing at all. I don't believe animals were put on the planet to be used to mess up and play with, I find it to be cruel. Who would want a life like that I believe they deserve equal rights. Its an issue very close to my heart. Its a shame so many research dollars go into looking for non-natural solutions, when there are so many naturally occurring things that can heal. Its all about the money though.
Animals used for testing are kept in better conditions than most pets. Until they're tested on and killed, of course. But lab animals have a high standard of living and health for most of their lives. Many pets cannot say the same. Nor can many animals in the wild. If it were not for testing, many of these animals would have been killed ("pest control") or not born at all. And I would not want to take drugs that hadn't been trialled before. If they've been trialled on humans for over a decade, fine - but if they hadn't done animal testing first and it was a new drug then no WAY would I take that drug. (Cosmetics are fine for human trial only though.)

Lab animals are kept in infinitly better conditions than a lot of meat animals too. Same for a lot of wool-providers, egg-layers and milk-givers. Not that I'm saying these animals are always abused, just that lab animals HAVE to be better kept because lab animals can't have a secondary illness prior to testing.
