I lost my cat one evening. I was sure she didn't get outside, but she was sneaky. She was gone all night and not anywhere the following day. I looked in all the cupboards and the refrigerator because she was once closed in there for hours! I called her, shook her treat container, and looked around outside. The secretary at the office put out an APB on her for all our residents. In the afternoon a neighbor stopped by, and I told her I believed my cat was gone for good. Then we heard a meow. We thought it was outside under the window, but nothing was there. We looked at each other wondering if we heard that or not. She left. I went back into the kitchen and heard a meow again! Finally, I started opening drawers in the area where I heard her, and she was lying in an empty drawer where she had been all along. At least 20 hours without making a peep! She looked at me like I was disturbing her, then ran to her litter box :-)
