    First, 'door knockers' here is very informal (and not very accurate). Those would be some kind of printed paper that has a message against, or protesting, the testing of animals (or the testing of something -- like a drug -- when used on animals for experimental purposes). So these things are not really door knockers at all, but a paper message that is meant to fit OVER a door knocker, so that you can just walk to somebody's front porch, and hang the animal-testing-protest message ON the front door -- where it will be noticed by whoever lives there, the next time they enter the house or apartment, etc.
