Gray Syrian hamster with white belly, lost yesterday

I lost my gray Syrian hamster yesterday around 3pm after I was cleaning his cage and let him roam briefly on the living room floor. He’s about 6 inches long, with soft gray fur and a white belly, a tiny dark patch on his left ear, and a faint tan stripe along his back. I last saw him dart under the couch near the Target on Madison Ave in Mankato, and I’ve been hoping he’d come out since. He’s pretty shy but curious, and I adopted him last year as a gift from my sister—he means a lot to me. If you’ve seen him or maybe brought him in, please get in touch; I can swing by to pick him up as soon as possible.
