Blue-ribbon brown-and-white long-haired guinea pig

I lost my blue-ribbon brown-and-white long-haired guinea pig yesterday around 3pm. He’s Abyssinian-type, about the size of a small orange, with tan and white fur and a white patch on his chest. He wears a bright blue satin ribbon tied around his neck and has a tiny crescent-shaped scar behind his left ear from a vet visit. I last saw him near Rosa Parks Circle downtown Grand Rapids, around the Monroe Ave NW bus stop by the Grand River, and he slipped into a narrow alley behind the Meijer on Pearl Street. This little guy is super social and has sentimental value—he's been with me for 2 years since my grandmother passed. If you find him, reply here or email me at [email protected].
