Help Vader

I am a volunteer in Greece and i try to help as many cats as possible, i foster over 20 cats and i have 8 at the clinic these days. A few days ago i found a kitten outside my home about two months old and i took it to the vet for a check up. Unfortunately the news are not good, he had a CT scan which showed congenital thoracic lordosis as a result of which the heart has moved to the right preventing the development of the right lung, one of his lungs does not inflate. The last thoracic vertebra is 5 millimeters from the xiphoid process of the sternum. At the moment he has no symptoms but at any time he may be paralysed or he may die. His expenses at the vet are alredy over 500 E due to x-rays and a CT scan. the total debt that i have is almost 10.000E so i need your help with Vader's expenses so i can continue trying to save more cats that need help.
