Dena,
I do hear some positive in your post now, maybe even a glimmer of hope. I do hope that you give it a tiny, tiny, tiny bit more time to see if Zoie is finally making it through the storm. I know that you want her to be healthy and happy and to be apart of your family. I also know that you've spent so much already, it would just really suck if she was really starting to get better and you had already given her to the rescue. The decision is ultimately yours, I know you are trying to do the best, and I hope you know that we all are behind you, whatever happens.
