Thanks to many of you for checking up on Sophie. We have spent a little time each day at the vet, and she appears to be improving. Her mobility is increasing (including the wagging of her long, bushy tail -- something we had missed terribly) but we still are confused about her condition. We'll take this, along with the rest of life, one day at a time and wait to see what happens. And Sophie will enjoy the privilege that comes with her illness - sleeping next to my daughter, sitting on the furniture, and being crooned over by us all.
