Sounds like a good move. I'd be more concerned about restricting acidity
and phosphorus, right now, than restricting protein. Phosphorus restriction
is more important than protein restriction because phosphorus retention and
hyperparathyroidism can occur in renal cats *before* serum phosphorus
concentrations rise above normal.

Neither am I. The problem is k/d is energy-dense (477 kcal/cup) and
protein-poor (6.7 g/100 kcal). So, I don't know if he could eat the volume
of food necessary to take in enough protein before he reaches satiety.
Hill's should make two versions of k/d- one for stage 1-3 that contains a
little more protein and one for stage 3 and 4 CRF. Cats have a higher
protein requirement than dogs and can't adapt to a low protein intake. If
they can't get enough protein from their diet, cats will start to metabolize
body muscle proteins. That's why so many renal cats deteriorate and look
emaciated- because of muscle wasting. Protein deficiency also results in an
impaired immunological response and reduced resistance to infection and
reduced hemoglobin production that leads to anemia. Protein restriction in
cats is very tricky business.

Ever since Nutro went off fixed-formulation and onto least-cost formulation,
I haven't had a clue about the nutritional values of their diets because
they vary so much from batch to batch. The phosphorus and calcium levels in
all Nutro diets were rising steadily for a few years before Nutro pulled the
typical analyses from their website. High P and Ca contents in a cat food
are usually a sign of poor quality meat (more ground up bone-less actual
meat). Taking him off Nutro is one of the best things you can do for him!
Believe it or not, I was strong proponent of Nutro years ago- until they
changed their formulation.
Now with the

Actually, Iams Ocean Fish & Rice isn't too bad- about .75% phosphorus (DMB).

Could be. Cats generally eat to meet their energy needs- when they've met
them, cats usually stop eating- unless their satiety cues are overridden by
exceptionally palatable diets or some behavioral problem.
Best of luck,
