ABBY IS HOME!! My thanks to all the people who posted suggestions and gave support. Without your advice, I am sure that she would still be missing. A special shout out to Diana who gave great advice along with others. We put Abby's cat condo, a familiar blanket, food and water on the back porch. She appeared deep in the backyard and was very tentative exploring skittishly. After about 1/2 hour she came up on the back porch. We had opened the door a bit and eventually she walked in. She raced to the next room and we closed the door. I burst into tears.
