Thank you so much for the link. It was very informative. Now, I'm really questioning the U/D food. I hated it from the time he was put on it and I'm really hoping the vet takes him off it permanently and allows him to go back to his old organic food supplementing him with I think potassium citrate medication. There's no guarantee with any diet that the stones won't return at some point. First this scary condition has to clear up and I sure hope there's no recurrence!
