Missing Small Black Cat, No Collar

Last seen yesterday evening 12/1/13 around 5pm on Dunnell Rd. She has no collar although she is microchipped, indoor cat who escaped. She  is approximately 4 years old, small, lightweight, spayed, solid black shorthair cat. Her name is Mischa, she is very friendly, but may be scared outside in unfamiliar surroundings. Please email allisonot@gmail.com if you see her or have taken her in, we are very worried!  Many thanks.
