Last Monday, our office cat, Zachary got out and has not returned. He was only in the new place for about a week. I have spoken with the neighbors on either side, one is a home and one is a store. There is a junkyard beyond the hillside that he ran to, I spoke with a woman yesterday and she has a feral colony that she cares for. She is on the lookout for him as she has no black cats in her colony and a few blocks down there is a place that has another feral colony and their caretaker is watching out for him too. I have left his heated cat house and litterbox by the warehouse door and put a pillow with his scent tied to a tree. I will put his old shelter on the hillside in hopes he picks up on the scent in there. I am even going to the old office but I think it is too far for him to travel and I am worried about the traffic he would have to face. We are putting up signs with a reward offered. Is there anything else I could possibly do? We leave the warehouse door open all day long in hopes of his coming back. I don't know if a cat can find his way back to a place he was not familiar with-is that possible? I am more upset as each day goes by. We took so long to get him that I just can't believe he doesn't want to come back.
