Gray tabby cat with white paws, lost in Salem

Hi, I lost my gray tabby cat, Mochi, yesterday around 7:45pm. He's a medium-sized cat with gray fur, white paws, and a small black dot on his left ear; he wears a blue collar with a tiny silver bell and a name tag that says Mochi. Last I saw him, he was near the Salem Public Library on Liberty Street SE by Riverfront Park, but he tends to wander. This cat means a lot to us—it's been a tough week, and Mochi is a gift to my kid; any sighting helps, and I’d be incredibly grateful to have him back.
