Is Weruva cat food okay for my cat with high kidney numbers?

In looking over Weruva's website, I see that they claim their food to be very low in phosphorous level. That's good, as phosphorous levels in the food should be low in cats with kidney problems. The problem that I see with the food is that is does not state if it is high in protein or not. The website says it has high quality protein, but does not provide if there is a restricted protein or not in the food. In cats with high renal numbers, it is recommended to have restricted protein levels in the food. That's because many of the toxic products that accumulated in the blood due to kidney problems are due to protein breakdown, so it's important to have reduced levels of protein in the diet. Because cats are obligate carnivores, however, this protein restriction has to be done with care. Given I cannot find any information about this food being low in protein, I would not recommend feeding it to Twitchy. It would be better to feed her a kidney formulated diet, such as Hill k/d or Royal Canin renal. I would feed her a wet food instead of a dry kibble.
