Hi Almur
My cat also has CRF, after she was diagnosed I put her on Wellness canned Chicken, Beef & Chicken and Turkey as those 3 varieties have the lowest phosphorus levels. That is what your kitty needs more than low protein. Cats being obligate carnivores need protein, when you reduce the amount of protein they are eating the body doesn't function as well.
The debate over whether low protein is beneficial to kidney cats is ongoing with more people choosing high quality protein over low levels. Alot of the low protein foods are unappetizing to cats, who will eat mostly based on what smells & tastes good, just because a food is low protein/low phosphorus & says it is for kidney health it won't be of any benefit if the cat won't eat it.
What you want to look for in catfood is as close to 1% or lower in dry matter basis for phosphorus, but keep in mind you want natural healthy non-chemical ingredients such as those in Wellness.
