Humphrey's a handsome rough haired ginger guinea pig - with attitude. He's fearless, adventurous, accident prone, podgy due to an unquenchable appetite for carrots, broccoli and lettuce, and has an inquisitive nature that leads him into all sorts of trouble. Humphrey shares his large hutch with his rather timid companion, a smaller smooth haired black guinea pig named Sooty. They are devoted, enjoying a surprisingly inclusive social life with their human family.
