Vet called today and said he believes Cass has turned the corner. She is finally eating and drinking every time they put it in front of her. She is wagging her tail and gets up when someone approaches her. She was very detached and lethargic until this morning. Her blood count is rising too. Internal bleeding is still a high risk and he is going to keep her under medical care for a little longer. She may be ready to come home this weekend. He sent my wife a video of her from this morning. I teared up when I watched it. I hope the worst is over. Thanks for all of the support.
