I dont know what the answer is for the urinary and kidney problems. My other cat Toby had the cystitus and was on the urinary food. Perhaps there is a food that will deal with both. If not, maybe doing half and half will help, Dillon only ate the kidney food half of the time, maybe trying to balance the diet to help both problems will help. I was supposed to give Dillon another tablet along with the bp tablet, one to help his kidneys. I knew I would never get both down him in a day without stressing him out. Plus I had read that the other tablet could send the creatine up before it came down, I decided against it. I think you have to balance it out in your mind and the cat being happy and not stressed. As long as the worst symptoms are controlled for coco and he is happy, that is the main thing.
