I am wondering if it is some permanent damage from the poison before? Seems to me if your vet pulled her through before, he would be more informative towards you, he has a lot of his time invested in her already and should be more sensitive to your need for answers.. I Hope she can overcome this and get better to live the long happy life she should have.. ((((HUGS)))) to you for all you have been through and what you are going trhough right now. All of us here know what a blessing these babies are in our lives and feel your pain and worry.
