Lost orange tabby near Broad Street Market

I lost my orange tabby cat, Milo, yesterday around 6pm near the Broad Street Market on Market Street in Harrisburg. He's about 11 pounds, with a white chest and paws, bright green eyes, and a blue breakaway collar with a tiny silver heart tag that reads Milo. He has a small white diamond patch on his left shoulder and a tiny notch in his right ear. If you spot him, please call me as soon as you can—I miss him terribly; he's been my companion since he was a kitten and the apartment feels empty without him.
