Tiny gray dwarf hamster with blue harness

I lost my tiny gray dwarf hamster yesterday around 4pm near the Target at EastChase Parkway in Montgomery. He's the size of a walnut, with soft gray fur, a white belly, and a faint white crescent on his right ear. He was last seen wearing a small blue plaid harness. If anyone found him, please email me at [email protected]; this little guy has sentimental value—my daughter saved up for him, and I really need him back.
