The discussion is as regarding dogs. But the only diet work as re: protein amounts in cats with CKD that I'm familiar with is the Finco 1998 study, that indicates protein restriction does not impact progression of the disease: http://www.ncbi.nlm.nih.gov/pubmed/9582959?dopt=Abstract
This is not to say that phosphorus shouldn't be restricted - but phosphorus loads can be reduced and still feed a diet with appropriate amounts of protein for a cat.
