The saying goes that not all heroes wear capes. This one, however, certainly does.
Austin first became passionate about helping the homeless after he watched a TV show about a young panda who was left without a place to live after being abandoned by his mother.
His dad, TJ Perine, told CBS news how after discovering the plight of the hungry and homeless, little Austin decided he wanted to spend all of his spare money that would otherwise have spent on toys on "chicken sandwiches for the homeless instead".
Since fighting for the cause, Austin has already set up a PayPal account, where people can donate to help the homeless, as well as a GoFundMe page.
After appearing on CBS News, he now has followers on Twitter from high profile accounts such as Burger King and Fight Hunger, who have pledged to support him in his quest.
