Grey tabby with white paws - lost in downtown Shreveport

I'm Priya Patel, and I'm really worried about my cat. I lost my grey tabby with white paws yesterday around 3pm, in downtown Shreveport near the Strand Theatre on Crockett Street. He's medium-sized, about 10 pounds, green eyes, a small white heart-shaped patch on his chest, and a pink collar with a tiny blue bell. He can be shy with strangers but he's friendly once he knows you; this cat has been part of our family for years, and I'd love to get him back home.
