Good news this morning! I had Gabby in my lap this morning while getting all of her meds in line to give to her. I felt something scratching my leg and when I looked down, she was trying to lift that leg up on to my lap as it had slipped off! First sign I have seen of any movement in her hind legs.
She also had a BM and it was not diarrhea! I have mastered expressing her bladder; so things are going pretty well.
