Some good news! The owner in Texas found a friend on island here who will be traveling to Texas in a few weeks, and he came by and picked up Sophia to take care of her until then. He says he'll carry her onto the plane, and I'm so glad it worked out. I had actually had people ready to adopt her if I wound up leaving island before the owner figured something out, rather than sending her to the Humane Society, but I'm much happier knowing that the little girl will be home with her mommy soon. 🙂
Thanks to all who helped with advice on getting Paco and Sophia to at least tolerate each other!
