I'm so glad you found her. Kittens can hide in the strangest places. When I was a young girl and I had a kitten named Puff, I thought I lost her too. She was in the bathroom and the door was closed so I knew she had to be in there somewhere. She had manged to crawl under the cabinet into one of the bathroom drawers. After spending some time searching for her, I just happened to open up one of the bathroom drawers and she was inside of it sleeping. That's how little she was.
