I had a 10 day old kitten that was on death's door. She had pneumonia and hypothermia and was dying in my hands when I rushed her to the vet. He said that she was too far gone and we could either euthanize her or take her home to make her comfortable, but she would probably not make it through the night. I took her home and I sat with her wrapped in a towel with a heated pad for two days while taking her temperature ever hour. She eventually did pull though and the vet said she was a miracle kitten.
