Gray and white hamster, pink nose, lost

I lost my gray-and-white hamster named Niko yesterday around 3pm. We were near the Santa Fe Railyard Park, walking along 1st Street by Cerrillos Road, when he slipped from his light-blue travel cage. He’s small, about the size of a lemon, with a soft gray coat, a white belly patch, and a tiny pink nose. There’s a barely visible scar on his left ear and a small white patch on his belly that should help ID him. He’s been with me for years and losing him has me really worried—he was a gift from my grandmother and means the world to me. If anyone spots him, please message me right away.
