It's so good to hear that little Willow is eating again!!!
I have just read the whole thread and was unaware of the situation until now. I know sometimes animals won't eat when they need the white blood cells, that would normally go to digestion, to heal with other things first. Plus the fact that your love has given her the will to survive and to eat.
Do you have a food processor?
Gosh, it must have been very difficult for you to watch her last night in this horrifying condition, not knowing if she was ever going to eat. God bless you for saving her life. I'm praying she makes it, and that you will take care of yourself, as well. I apologize for not knowing more about your situation, but have you considered keeping her?
