You've probably seen a commercial or two of animals behind cages with a sad song playing in the background begging you to cry a long with them...and sure enough you do.

After all, few things are sadder in this world than an innocent animal going through pain and suffering. What you are about to experience may not be as sad as these commercials (unless you’re really, really, really sensitive) because, except for a few genuinely depressing fact, these aren't that bad.
