Gray Syrian hamster with blue harness and bell

Hey— I lost my gray Syrian hamster yesterday around 3pm. It wears a tiny blue harness with a small silver bell that jingles when he runs. We were by the Main Library on University Blvd in Tucson, just outside the UA Student Union, and a gust of wind must have knocked the harness loose; he bolted into the shrubs near the fountain and disappeared. He’s the size of a ping-pong ball, with a white belly and a faint orange stripe along his back, plus a pink nose and a tiny scar on his left hind paw that you can feel if you touch him. This little guy is a gift from my daughter's grandfather, and we really need him back.
