Lost & found small mammals in Inland Empire

Tan-and-white dwarf hamster found near Victoria Gardens, Rancho Cucamonga

I found a tan-and-white dwarf hamster this afternoon around 3:45 pm behind the Victoria Gardens parking structure in Rancho Cucamonga, in the Inland Empire. It's tiny, about the size of a ping-pong ball when curled up, with a soft coat, pink nose, and a small white crescent patch on its chest plus a little notch on the left ear. It was wandering near the pet store in the Victoria Gardens area and seemed stressed but cooperative when I offered a treat. There's no collar or ID, and I’d love to reunite him with his owner—if you recognize him, send a note through this listing and we can arrange a safe meetup.
