I only found this thread today, but I know how your heart feels when one of your babies go missing. I've had that happen just lately. Sunny sneaked out the back door! The next day we went out and posted reward signs and got one call but it wasn't Sunny. Then two days later he just showed up at the back door. Hubby just happened to be in the room and heard him. Maybe he would have left again if nobody had heard him. There were alot of relieved tears from all of our family. But when I used to let cats outdoors, I had a few cats go missing for months. So DON'T GIVE UP. Your little Mystic is so beautiful that I am sure someone has him. If he gets a chance to away from where he is, I know he will find his way home.
