My 4-year-old F4 male is currently hospitalized with a kidney and bladder infection. They were able to catheterize him and remove the blockage, so he's doing well. They have him on a special urinary tract diet. I just spoke with the vet tech and she said that he will need to stay on that diet. I asked her if the food contained grain because he cannot properly digest grain. She said that it does and does not know of any urinary tract foods that don't contain grain. I asked if he had diarrhea. She said he did, but they were attributing that to the antibiotics he's taking. I told her it was probably the food. Does anyone know of any urinary tract support foods that Savannahs can digest? I'm at a catch 22 here. Please help!
