There are a few things you could try - and I would tend to vary them from time to time. Human grade chicken, cooked, cooled and cut into small cubes would be good, high in good protein and low enough in phosphorus.
If its chronic renal failure, do you know how he developed it?

Unfortunately, it's chronic. However, the vet said he may live a year or two with a good quality of life, because it was diagnosed and special diet started before he had any symptoms except increased thirst and urination.
He's young enough to need behavior training, and we like to use treats to reinforce learning, but I don't want to give him treats that put stress on his kidneys.
Hi. Does your vet know whether this is acute renal failure or chronic (congenital) renal failure?
