I have had Abraham a two year old adoption for about six months. He has been eating Blue Buffalo Indoor Cat food 1/4 cup dry 2X per day and 1/2 can of wet 1X per day since we got him. Recently he developed a UTI and the tests showed that he had bacteria and struvite crystals. I checked in with the vet today and the office staff suggested a low ash low magnesium food. Does this qualify? He looks so much healthier and his hair is more beautiful then when we first got him. He was also only 8 pounds when we got him and he is now a healthy 10.5 pounds. His litterbox is cleaned 2X or more per day. I am anxious to hear what the general opinion is on Blue Buffalo.
