Calico cat, Luna, lost in Bakersfield

Hey, I'm really worried because my calico cat, Luna, disappeared yesterday around 3pm. She's about 9 months old, around 8 pounds, with orange and black patches and a white chest. She has a tiny pink collar with a small silver bell and a white heart-shaped patch on her chest. I last saw her near the Starbucks on 19th Street and California Ave in Bakersfield, and she darted into a little alley behind the shops, so she might be hiding. She's generally friendly but timid with strangers, so if you spot her please call softly and leave food near your door—she's my little shadow and I really need her back.
