Susan, I am so sorry and understand completely what you're going through. We have had three cats disappear over the years, and all were "special". They were all microchipped, too. I spent months looking for each of them, and finally had to give up. We never found any of them. I just hope that they found a wonderful new home. You have to believe that Squeek is tougher than you think, and smart enough to find a safe, warm spot to hide. She may still turn up, even weeks later. Prepare yourself for the worst, but keep hoping for the best. Prayers from here. ((HUGS))
