Cream-gray hamster with blue collar missing

I lost my cream-gray dwarf hamster yesterday around 3pm. I last saw him near the kitchen, but he slipped out and vanished around Maple Street by the Chautauqua Public Library on Main Street. He’s tiny, about the size of a thumb, with a cream patch on his left ear and a blue collar with a small silver bell that jingles when he runs. This little guy means a lot to me—he was a gift from my sister and has sentimental value. If anyone spots him around Riverside Park or near the library, I’d be forever grateful to get him back.
