We're all sending our thoughts and prayers from here!! I had a dog missing once for several hours and it was the worst feeling. It's good you saw her this morning. At least you know she hasn't been out all night.
Putting up signs on lightposts and street signs in your neighborhood is a good idea. My dad recently saw a sign several blocks from his house about a missing cat and recognized it asa cat that has been coming to his yard at night for the past few days. So he called the people and now they are both watching for her. So, you never know.
Try to keep your spirits up and know that we are all thinking of you! Was Buddy still in his cage and she slipped out somehow??
