I am sure she is acting strangly because of the after effects of the operation and she will feel the operation site. The vet must feel there is some hope if he is willing to operate twice to try and get her well. Keep her nice and quiet. Make sure she gets plenty rest and lots of tender loving care. I am so sorry she has gotten this as she does not deserve this especially when she is just a youngster. Fingers toes and everything is crossed for her to have a speedy and full recovery. Hugs to you both
