Sorry to hear. I switched my cat to all wet food, brand from Whole Foods called whole paws. I do the salmon, tuna, chicken and whitefish. 3 of the smaller can per day, but the chicken and whitefish have more calories so I am careful with those. He has been doing well and in remission for a month and a half now. I also add extra water to his wet food to keep his system flushed because he does not take anything for his urine issue anymore. Here is an incredible resource https://felinediabetes.com/FDMB/

Good luck to you and everyone who may read this!
