We won't know for sure until tomorrow when the last results come in, but the vet is pretty sure that it is a liver shunt.:( It explains why even though I was feeding more than enough he was so skinny, and why he drinks so much water. If the results confirm a shunt I have to start looking into surgery to correct it.:( and the cost is going to hurt. I will most likely have to travel to A&M college station for the surgery, since they will let me make payments. I can see this getting very expensive very fast:( I'm so sad, and worried about my little boy. He is my world, they all are. Hopefully everything will turn out ok.
