JustMe--do you know if those Wellness numbers were adjusted for dry weight?  Since they are grainless, they will be higher in phosphorous.  I suspect the numbers still need to go through the calculations to get true phosphorous levels.

Skeptic--My 7 year old kitty was also just diagnosed.  I'm feeding canned Felidae Platinum because it has lower phosphorous levels & she's doing well so far on it (actually gaining too much weight).  A lot of cats don't seem to like it that well though.  Maybe mix it with another flavor.  It's not canned at any of big companies & not involved in the recall.  

I was feeding Wellness canned because of it's grainless & higher protein, but am staying away from the products produced by canneries with recalls.  I haven't seen any problems with it on the forums, but the high meat formulas do tend to be higher in Phosporous.  Felidae Platinum is listed with .125% P compared to the .3% average for Wellness.  Dry weight calcs for the Felidae came to around .9%, I think you want to keep it under 1% for the CRF kitties.  You CAN use Phosphorous binders though to keep P levels down in blood, that lets you feed more types of foods to a kitty that isn't eating.  I will not feed the vet diets, which my vet wants me to do.

Check out the forum called 'What to feed my CRF kitty' here on itchmo too, it shows dry weight calcs & food suggestions.  CA Naturals chicken & rice dry cat food is listed as low P if you want a dry food.

The Wellness numbers do need to be adjusted for dry matter, and will come in a little high for CRF (the turkey, for example, is 1.27%). AAFCO minimum phosphorus level for adult maintenance is 0.5% DMB, so anytime you see a number lower than that you'll know it's not been adjusted. As for why it's not always on the packaging, there are only a few things that are required to be listed and phosphorus isn't one of them. I tend to look for foods that make this kind of "optional" information easily available.

But I agree with the consensus that making sure the cat eats something is more important than what they eat. That's why you'll hear a lot of CRF cat parents talking about Fancy Feast. Not because it's a good healthy food (IMO it isn't), but because it's very palatable and sometimes it's the only thing a sick cat will eat. I wouldn't feed it as a main diet, but if your cat likes it then keep some around in case you need to get food into them.

Personally I feed California Natural chicken and rice dry, and have not yet settled on a wet food though I plan to try Felidae. It is lower phosphorus than most but contains cranberries, which are not that great for CRF cats. This is my main problem with the better foods on the market: most of them have a whole lot of unnecessary ingredients in tiny quantities that serve more of a marketing purpose than anything. I put up with them in order to get the better quality protein and absence of garbage ingredients, but I prefer simpler foods.

OF - Thanks for figuring out the dry % phos for Wellness.  I forgot about the cranberries in the Felidae--I was concerned about this when I first started feeding it to Tessa because I had read it can be too acid, but she's been staying about the same for several months now so guess i just put it out of my mind.  It might be a concern for cats with higher numbers. 

I did calculate the other 2 Felidae formulas & they both come in below 1% too, they are both at .25% on the can, & they don't have cranberry, so those might also be an option--I feed them several times a week to give the cats variety, hate to feed the same formula all the time. 

The California Naturals canned is totally simple (almost too few ingredients), don't know it's numbers but since the dry is low, that might work too.  Since it's Menu made, I won't use it but a lot of people feel safe if the company hasn't had any recalls.

Orange Fuzzball,
Can you direct me to the formula for calculating the phosphorus content adjusted for dry matter?  I didn't realize I had to do further calculations on the figures Wellness gave me.  Guess I'll have to restart phosphorus binders.  Thanks for any help.

JustMe: No problem, here's one site: http://www.thepetcenter.com/imtop/dm.html. Someone here pointed it out to me, and it's a lifesaver.  Smiley

petslave: I had looked into the CalNat wet formulas but they all came in a little high. I'm not too worried about the Menu connection since Natura tests their own foods and the plant they use hasn't had any recalls, but it'll be much better when they get their own cannery. It seems to be harder to find a low phosphorus wet food that's safe - I still have no idea what I'll use as an alternative if the Felidae doesn't work out.

I must be going blind.  LOL.  I used that site to figure protein, but I don't see anything about phosphorus.  Thanks anyway.

It works for anything - protein is just the example they used. The calculation is exactly the same.

 Huh I am horrid at math. Can one of you kind math scholars tell me how much phosphorus is in the Wellness canned series? Or direct me to a website. The site I saw stopped giving the numbers for Wellness. Sad Another site I saw had the phosphorus in mg which makes me even more confused.  Huh

KimS--here are some general numbers you can use.  Look at the % moisture on back of can to see which one is closer to yours.

If it says 80% moisture on can:
0.1% phosphorous (or anything else) listed on can = 0.5% dry matter
0.2% = 1% dry
0.3% = 1.5% dry
0.4% = 2% dry

78% moisture (Felidae has this %)
0.1% listed on can = 0.45% dry matter
0.2% = 0.9% dry
0.3% = 1.36% dry
0.4% = 1.81% dry

This is how I calculated the first example where the back of the can says 80% mositure & 0.1% phosphorous in case you want to try--just 3 steps:
Subtract the moisture number from 100:  100-80 = 20
Divide phosphorous nimber by this number:  0.1/20 = 0.005
Mulitply this number by 100:  0.005 x 100 = 0.5     
            Voila!  This is your Percent dry weight!

Most canned food is between 75-80% moisture so if it doesn't list it you have to make a guess.  Gooier formulas more towards 80%, crumbly formulas towards 75%.

I have a story to share about food that made a difference to the kidney health of my cat. 

I had used Science Diet's Nature's Best Adult Cat Food with Real Chicken/ Science Diet's Feline Adult for a few years til last March.  Back in March, I had blood and urine test done on my cat (14 years old) and the vet said he has protein leaking through the kidney wall (sounded bad) and advised low protein diet. 

So, I have been feeding Fromm's Salmon a La Veg for a few months now.  I also feed my cat wellness canned food.  With this combination (roughly half each), I was able to improve the kidney test result of my cat.  With the change of diet, my vet was impressed that the the test result from last week looked real good.  There is no trace of protein leak.

I am grateful that I use Fromm and wellness.  I would not go back to any Science Diet product again with the food contents they use.  I do think high quality protein made a big difference.  I chose Fromm's Salmon a La Veg as the phosphorus level is lower than other food.  Other dry food with lower phosphorus level that I will try are Fromm Senior Gold and Wellness Indoor.

Hope this helps
