I'm so sorry to hear this. Hopefully she's still close by. I would also try to go door to door and talk to neighbors to alert them about her. Maybe one of them has seen her. If she didn't have a collar on someone may think that she's lost or a stray and may even take her home with them. Sometimes cats will also get locked up in sheds or garages so you may also want to check these things out. I sure hope that she comes home soon. I'll keep her in my thoughts and prayers.
