Looking for grey cat that was given away

About 4 years ago, my ex-girlfriend had given away our cat on Bismarck here to some farmer that lived close by 2 the Bismarck Mandan area. Her name was miss biggles. I know it's a long shot, but I'm hoping that somebody knows this farmer or that someone shares the add with him. My son and i are praying that she makes it back home to us. Ive been searching for her for awhile now please help somebody. She was given away on bisman for free and they lived down on santa fe ave.
