To get an idea of what the latest viral video is all about, just read a few of the headlines that have been written about it around the web:

“This Fireman Saving a Kitten Is the Only Video You Need to See Today”

“It’s OK To Cry While You Watch This Fireman Rescue An Unconscious Kitten”

“Fireman rescuing kitten on GoPro camera warms our icy hearts”

As these reports say, the video shows a firefighter, Cory Kalanick, entering a smoke-filled building, finding an injured kitten on the floor, and attempting to revive the kitty outside with an oxygen mask and a wash of water. The kitten finally starts moving, and the video ends with Kalanick giving the cat a comforting hug.

The clip, which has garnered nearly 5 million views as of Friday morning, was shot using a camera worn on the fireman’s head (the video is part of a marketing campaign for camera company GoPro).

Sadly, the kitten, who had been named Lucky, was taken to an emergency vet later the day he was rescued, and passed away of lung damage caused by the smoke. Still, the firefighter’s valiant effort to save the cat makes this video worth a watch.
