Lost dwarf hamster with white patch near Ukiah Safeway

I lost my tiny dwarf hamster, Miso, yesterday around 3pm near the Safeway on North State Street in Ukiah. He's a soft grey with a white belly, about the size of a large grape, and he has a distinctive white patch on his right flank. He often carries a tiny blue chew-toy bone in his mouth and sports a faint scar on one ear from a past tumble. He loves sunflower seeds and squeaks when he hears crinkling bags. This little guy is a beloved family pet with sentimental value, and I'm really hoping someone spotted him.
