Lost black cat named Oliver with green eyes and a red collar with a bell, last seen near Maple Street in Fayetteville.

My black cat, Oliver, has gone missing since this morning. He was last seen near my house on Maple Street in Fayetteville. He is quite shy but very friendly once you earn his trust. He has striking green eyes and wears a red collar with a small bell. I've been searching the neighborhood and posting flyers, but no luck so far. Please help me find him!
