Calico cat with green collar and bell

I lost my calico cat yesterday around 3pm near the Walmart on West Main Street in Tupelo, North Mississippi. She's about 9 pounds, has a white bib, orange and black patches, and wears a bright green collar with a tiny bell. She sometimes limps a bit on her right hind leg and has a small white scar on her left ear from a past scratch. She's friendly once she trusts you but will bolt if you hear loud noises, and this cat means the world to me—she's a rescue I nursed back to health and I really need her back.
