My cat is dying of kidney problems?

What is the best non-prescription cat food for a cat with kidney problems?

• My cats are happily switching over to Evo (and loving it) and my mother wants to put hers on something better too. But one of their cats has kidney problems so the protein content in Evo would be too much for him and there's no way to keep them out of each other's food. He rejected numerous prescription foods so now he's eating Purina One (boo!), a mix of urinary tract and sensitive systems. He's doing alright but he's fairly skinny and one of the other kitties is a little chubby. I want to help find a good high quality food that will work for them all. They get some wet food. I was wondering about the Evo wet, since the protein content is much lower but they do need some hard food left out too. So if anyone has experience with kitties with kidney problems, please share what seemed to be the best foods for them to help me with my research. Thank you!

  I ran into this problem years ago... unemployed & the cost of Rx food was through the roof. Nutro-Max had just come out w/ their Senior formula... the silver bag striped like a bumble bee. My vet ran the formula percentages & told me that they were close enough to the Rx formula that I would be safe feeding the Nutro-Max formula instead. My other cats (even kittens) liked the senior formula as well, perfectly safe for all to eat.
