Calico cat with blue collar near Garden of the Gods

I lost my calico cat yesterday around 3pm near the Garden of the Gods Visitor Center in Colorado Springs. She's about 9 pounds, white chest and orange/black patches, and bright green eyes. She wears a blue nylon collar with a tiny silver paw-print tag, and there's a small notch on her left ear from a past scuffle. She's very gentle but can be skittish around new people. Last I saw, she slipped under the fence near the parking area by the Visitor Center and headed toward the red-rock trail. I adopted her last year; she's my only companion and has huge sentimental value to me. If anyone finds her, please contact me immediately—I'm really hoping to bring her home.
