I assume you've had your cat's blood work done.
My cat has CRF has well. In fact, she's had it for about 3 years or so.
She was diagnosed by accident when the local vet said she needed her teeth cleaned (for $865.00!!) and I said ok and the first thing they did was blood work. Her urea and creatinin levels were higher than normal.
The local vet said she had a year or so left to live, but that I could help her by feeding her special Vet prescription diet KD (Kidney Disease) cat food and 2 kinds of narcs. As luck would have it, they sold both, imagine that.
I was quite taken aback at the time and called a friend of mine who is an animal nut and she suggested that I take my cat to a "naturalpathic vet" outside of Guelph whom she had a lot of respect for.
I figured what the hell, I wasn't getting a warm fuzzy feeling from my local vet for sure.
I packed the cat up and headed off for Guelph. The lady in question is a certified vet, but she's also a big believer in doing the right thing by way of lifestyle for the animal.
The first thing she asked me was what I was feeding the cat. Answer, Diet Eukanuba. She told me in no uncertain terms to stop feeding the cat ALL processed cat food. Including the vet sold gourmet cat food.
She (the natural vet) told me that ALL pet food, regardless of how they dress up the bag, is poisonous for our four footed friends. It's all crap, made from crap, made to be convienient for humans. Imagine food that doesn't rot - how's that possible?
Anyway, she had a convincing arguement - that vets make more money selling food and narcs than they do being vets. Hardly unbiased. We use pet foods to get rid of the bottom of the barrel rotting food, mix it with anything to fill the animal up and package it to be convienient to the human owners.
My cat was supposed to be dead two years ago. I have been making her chicken and veggies, or fish and veggies for 3 years now and she has lost weight (holding at 9 pounds) and is asleep right now in the other room.
The multi billion dollar pet food industry would like you to believe that pets somehow require some secret food that only they can make. Nothng could be a bigger pile of steaming horseshit. Well, your animal would probably be better off eating fresh horseshit than it would be eating anything by IAMS or Eukanuba (Proctor and Gamble and Colgate Palmolive)
Believe me, I am not a birkenstock wearing tree hugging hippie, but I do work in the corporate world and I know how they operate. If they could sell us cotton dipped in chocolate and get us to eat it for lunch, they would. Animals can't voice their concerns. So just ask yourself - Would you want to eat what you are feeding your cat or dog?
If the answser is no, then your cat or dog probably feels the same way. How'd you like to eat cheerios every day, three times a day, for the rest of your life?
I have had her blood tested 2 other times since the first time and her levels are increasing, but slowly.
I attribute this to the proper diet I am feeding her.
I have also taken her to the Cat Clinic in Hamilton where the lady who owns that clinic (Dr. Obrien) is a cat expert extraordinaire.
She is one of only 4 board certified cat practioners in Canada.

I highly recommend them and her. In fact, if you want to take your cat to see her, you need to specifically request her because she is so in demand.
I gave up on my local vet here in Toronto. I owe them for finding the problem early, but they are only interested in the upsell, not what's truly best for the animal.
I have been lucky and found that in my vet in Guelph and the cat clinic in Hamilton.
Perhaps you might want to consider a second opinion.
Feel free to PM me for my home made cat food recipe.
(BTW, after that last pet food scare - menu foods, I am more convinced than ever that feeding your cat or dog a sound diet is money spent wisely.)
