Oh, I am so glad this ended happily. And thrilled you were willing to help.
My little story about Buster in January, the YHR foster... He got out of our yard while I was having lunch with friends. (My husband let him out on the deck with Piccolo and Vivi, while he went to the garage for a couple of minutes.) I came home and I cannot tell you how upset I was about Buster being lost.
Fortunately, I have the best neighbors and friends in the world. They dropped everything and we had about 20 people looking for over 3 hours. Honestly, I will never forget their time and trouble and love them so much for that. So hugs to you and I bet your Facebook friend feels the same way about you, because you were willing to search.
