I am glad she is back inside. I am sure that one of the above ideas will be your answer. I too needed to use diapers on my diabetic cat who simply could not hold it long enough to get to the box. Indoor/outdoor combined with some plastic covering might just make a diference. I now have plastic on my furniture covered by inexpensive sheets or blankets. That way only the sheet or blanket needs washing in case of accident, but the upholstery is safe.
