Missing Tortie Cat in Gainesville - Help Needed

Domestic short-haired female cat. She is tortie-colored. While she is allowed out for supervised daytime visits, she got out at 8PM on July 3. We are worried that she got scared by some early fireworks and is hiding. She is a small (7-lb) and rather timid cat, who will not do well on her own for long. She has some familiarity with her surrounding area, but being gone long or straying far is very outside her normal behavior.
