Save Henry,the amazing cat dog!

Henry is in the critical care unit fighting really hard to survive. He was on deaths door when he arrived here. After many tests the vet only guess as to what was wrong with him was a congenital condition that could not even be tested for unless he was able to recovery from being in a semi comatose state.(offering the option to be put down  immediately)After  visiting with him in the ICU I can see that he knew that I was there and was having facial movements. He had  undergone a plasma transfusion that morning along with many other treatments.The tech informed me he should have been showing improvement right away. I knew he needed time. Low and behold later that evening he began to eat!!! If he can continue to be in care and gain more strength he can proceed with a CT scan to find the issue that is directly affecting his condition. Anything you can do to help would be greatly appreciated.
