The previous record holder was another Maine Coon that measured 48 inches. It was owned by Frieda Ireland of Chicago.
Hendrickson says Maine Coons are one of the oldest natural breeds of cats and are known for their mellow, relaxed temperaments. She says they're known as "the gentle giants" of the cat world.
Hendrickson says she and Brandsness decided to try for the record after hearing countless people say they were amazed by Stewie's length.
