:hugs Kerry, I'm very sorry for your loss.
You are so sweet bringing her home and caring for her like she was your own. You did the best you could, I know it must have been hard to lose her.
Thank you for hanging in there and keeping us posted.
Sorry, I disagree, I would not dunk her, that's likely to send her into more shock. If she's still really hot, then put her feet in cool water as previously suggested.
Do what you can to get her hydrated. Don't worry about food.
It would be good if you can examine her to see if she has any...
