The weekend came and went with my concern for Thomas growing.  He just doesn't seem to be getting weight on his bones.  I am not sure how weight comes back on emaciated people/ dogs/ cats.  He has very little muscle left and I wonder if fat gets added back from the places it was depleted from last.  Anyone know?    The big mystery as to why he became this 5 pound cat might have been answered.  I truly believe that his left eye sight is limited or he is blind.  His pupil does not have any light response which might account for his inability to take care of himself.  Well, he has a vet appointment sometime this week, when I can get out of Parent/Teacher conferences to take him...might be Friday afternoon.
