Austin's mom, Mari Brooks, works at the Humane Society of Genesee County, Michigan. For the last two years, Austin has spent much of his free time there, too, volunteering to take the shelter's dogs on walks and socialize with the kitties.
Earlier last month, however, something sad happened at home.
"Our cat passed away," Brooks told The Dodo.
Despite being understandably heartbroken over the loss, Austin still continued to help other pets in need.
