Thanks to all for the prayers and good vibes. Little Spooky is still missing

We've checked our local shelters and gotten on their lists, and with PetHarbor - need to call area vets still. We've gotten the word out to a few neighbors, but many have not been home this week (our neighborhood is always busy with people, cats - this week has been like a ghost town!) I had planned to put up posters today, but we are having a bad wind storm now (didn't work so well). Spooky doesn't really go up to people and doesn't wander - it's all just strange and very sad! He came to us as a stray kitten and made our front porch his home. There is another black cat that we suspect is a litter mate still in our area. He/She came visiting last week, but Spooky doesn't really seem to care for him/her. Maybe he ran off with him/her? We don't know where it lives, though. We do have a large apartment complex on our block that needs to be searched completely. Spooky LOVES our other cats (especially Winky and Faylene). In fact, we think he loves them and tolerates us!!!! Spooky is their little shadow!! And they miss him so much!! It's sooooooo sad for all of us!!!
