Tonya I'm so sorry you're going through this. I know the panic and fear and it just makes your mind think all kinds of crazy things. I just knew I would never see Leroy again and on day three his head popped up in the window!. We are pretty sure he got trapped in a garage or shed and couldn't get out until someone opened the door. If your neighbors have sheds or garages you may ask them to check for you. You know how cats hide and it would be easy to close them up and not even know they are there.
I think you have done everything else there is to do and the sad thing is now all you can do is keep calling her and praying. We are praying with you that Raven will get home soon!
