I read an article on the Iams pet food company's animal testing today. Little disturbing.

I am usually for animal testing. Certain things are both potentially dangerous and potentially beneficial, and it is likely much better to work the kinks out on a mouse than a person.

That said, if your food or makeup is so potentially dangerous that you need to run clinical lab trials on animals before releasing it, maybe you should just focus a little more on making safer products than working out the issues with dangerous ones. Seems like it would not be hard to do, really.
