We ALL have experience like that!! I had a neighbor who was convienced that her cat had gotten out, she said he ALWAYS come when he is called. We had a major search going on outside and couldn't find him and went inside for a break... Here he comes strutting up the hall, looking like he had just woke up and giving all of us that "WHAT?" look.... I knew he was inside her house somewhere sleeping all the time, she just had moved and she had boxes everywhere but she was frantic so I did the helping neighbor thing to make her feel better..

Chester did about the same thing to Rie one time and had her in tears!
