Yes, fire fighters are rough and tough. They charge in to burning buildings, they're always in harm's way, but their main goal is to save lives. Even if that life is that of kitten only weeks old.  

Take a look at this video and check out the dedication it took from Fireman Cory Kalanick and his crew to rescue an unconscious kitten from a burning house filled with smoke. Oh, one word of caution for any guys watching.  It's okay for you to cry too.

Sadly, we learned that the kitten later died, which makes this rescue video even harder to watch.
