Larry, there is hope. My girl Sonya has a under devoloped kidney. They beleive that this will eventually lead to Renal disease. She does drink alot of water and throws up occasionally. There is a special food out there called Hi-Tor Neo diet wet and dry food it is really low in Protein but high in vitamins. I don't know how far along your little buddy is and to be honest with you we just adopted Sonya so I don't have all the answers but if theres anything I can do to help please PM me I've been researching this for the last 3 weeks. .........Russ
