Keith Walker is a hero.  

A homeless man risked his life to save several cats and dogs trapped at an Atlanta animal shelter after it caught fire, the facility's founder said.

Keith Walker, 53, rushed into the W-Underdogs shelter on December 18 after a fire engulfed its kitchen.
"I was nervous as hell, I'm not going to lie. I was really scared to go in there with all that smoke. But God put me there to save those animals," Walker told CNN. "If you love a dog, you can love anyone in the world. My dog is my best friend, and I wouldn't be here without him, so I knew I had to save all those other
dogs."
While the shelter was not completely destroyed, the fire left it uninhabitable, according to W-Underdogs founder Gracie Hamlin."
