Gray dwarf hamster with white belly near Brighton Dome

Hey, I lost my gray dwarf hamster yesterday around 3pm in Brighton. He’s a tiny fluffball, about the size of a ping-pong ball, with soft gray fur and a white belly, and he has a small white patch on his right ear plus a tiny nick on his left front paw—easy to spot if you find him. Last I saw him, he was near the Brighton Dome on Church Street, just off New Road, darting into the alley behind the souvenir stalls. He looked a bit dusty and startled, but he’s otherwise healthy and loves sunflower seeds. I’m really worried—this little guy means a lot to me, and I’d be forever grateful if you text me if you’ve seen him.
