Gray tabby cat with green collar missing near Castillo de San Marcos

I lost my gray tabby cat in St. Augustine yesterday around 3pm. She's a medium-sized girl with a soft gray coat, white chest, and tiny white paws. She wears a green fabric collar with a small blue tag that reads 'Mochi'. There's a little notch in her left ear and a faint orange freckle above her right whisker—one of her few distinguishing quirks. I last saw her outside our apartment near Castillo de San Marcos on King Street, wandering toward the waterfront by the Bridge of Lions. She's shy with strangers but incredibly affectionate with me; this cat means the world to my family. If you spot her, text me and any info would help. Rewards offered for safe return.
