Gray dwarf hamster with white belly, Mochi

I lost my gray dwarf hamster Mochi yesterday around 3pm. He’s tiny, about the size of a ping-pong ball, with a soft gray coat and a small white belly. There’s a barely visible scar behind his left ear and a tiny patch of white on his chest, which makes him easy to spot if you know what to look for. I last saw him in the Tri-Cities area near the Columbia Center Mall in Kennewick, around the food court entrances, but he could have wandered toward the parkway by the AMC theatre and the Target. I’d be eternally grateful to anyone who brings him home; he’s my little buddy and he means a lot to me.
