One small step for morality....

A kicker to this. Some years ago the U.S. passed the Animal Welfare Act, which controlled the kinds of tests that could be done on animals. However, the act defines 'animal' as not referring to rats, mice, or birds. In other words, testing on animals is still allowed, but within limits. Testing on mice, birds and rats can be done without regard to pain and suffering. What kind of an act is that?
