Well, Boo made it through the night. Her temperature is normal and her glucose returned to normal after shooting up quite high early this morning. Basically, she is sleeping a lot and eating/drinking when she feels like it. That is how she has been at home for the past few months - a very sporadic eater. She is still receiving IV fluids to help hydrate her.
I am not expecting a miracle. She is 15 years old and I know that even if they are able to stabilize her, she might not have much time. I guess I feel like I want to get her through this critical period and see how she is doing at home. They said it might be 4 or 5 days in the hospital. We know it is going to be quite expensive to treat her, but she's family, and I could never let her suffer at home.
This is a blurry picture, but it's the Boo sleeping all curled up on an IKEA chair pad for our outdoor furniture:
