I agree. My boy, Cruz, seemed to be getting pickier and picker about his food and then I read a thread someone had posted about renal disease and poor appetite and decided to take him in for labwork. Turns out he a bad UTI (with no symptoms at all) and has serious renal disease. I'm not saying this is the case with your girl, but it was something I didn't know anything about and I never suspected he had a UTI. Sending good thoughts for Diana.
