Tiny hamster found near Irvine Spectrum

I found a tiny hamster this afternoon around 2:20pm, wandering near the Irvine Spectrum Center entrance on Irvine Center Drive in Orange County. It's a gray-and-white Syrian hamster about the size of a golf ball, wearing a bright blue harness with a small silver bell, and a white patch behind its left ear. It seemed healthy and curious, nibbling on lettuce I offered, and I felt a little hopeful about finding its owner. I know losing a pet is stressful, so I’d love to help reunite them—meetups can be at the Spectrum security desk or the nearby Starbucks.
