Hi, sorry I don't personally know of any dry cat foods that are suitable (I'm in the UK), but another option could be that you add phosphorous binder to a dry food. The binder doesn't mix as easily as it would into a wet food, but if you mix it up well the binder may absorb (or stick to the food) if left overnight. I should say that I've only tried this with dry treats, not with dry food itself, but I'm guessing the principle is the same...
Many people with cats who have early stages of kidney disease feed our kitties foods with good protein content. The idea of feeding low protein diet is not considered as valid these days, as cats with kidney disease are prone to losing muscle mass, and so really do need decent protein in their diets to help counter that. This is not the case however with
late stage kidney disease, where it
may ultimately be necessary to feed lower protein.
Do you know about the Tanya CRF website, there is a fantastic amount of info there.

I do agree with Sharon (above) that it is well worth persisting with trying to get your kitty onto a wet food if at all possible. Water is
so important for kitties with kidney disease. (But just be aware that switching to a wet food would likely reduce the carb content of the diet, and any insulin dose may need to be reduced.)
Can you just confirm; is your kitty diabetic also?
Are you testing his blood glucose at home? Do you have any recent blood glucose test data?
If the diabetes can be well regulated that can really help a kitty with kidney disease, as there is less work for the kidneys to cope with.
