Hello all,
Wondering about the phosphorous levels as noted on the food chart. .thinking of switching/ adding in a food while Trying to keep her phos level on the lower side. I see on the chart there is a column for phosphorous mg per 100 k cals as well as a column for phos DM. Which number should I be looking at and what is considered a good level in either column or both? Some of the foods listed have phosphorous levels listed as high as 6-800 in the KCal column. That’s sounds really high to me but maybe I’m interpreting the chart incorrectly. If someone could help clear this up for me I’d be very grateful. Thank you-Lisa
 
This is pretty vague and I haven't read the entire article. Our dog had failing kidneys and was then fed Hills KD exclusively. He was half dead when we got him and along with some meds his numbers were perfect within two months.
This link is from a search of "Excess Phosphorous in the Blood in Cats" in PetMD. It's a start, good luck.

Sometimes prescription food actually works!
 
Cats with kidney disease need lower phosphorus foods. Otherwise, there is no reason you need to look for low phosphorus foods for your cat.

Yes, some of the foods with more fish are higher in phosphorus. Also, the foods with meat-by-products in the ingredients (you'll need to find and read the actual food label to see that) are higher in phosphorus.

So, what is your reason for looking for a lower phosphorus food?
 
Since my cat Billy doesn't have anything wrong with his kidney function, I personally just avoid the flavors that seem super high compared to other ones, and make sure I don't feed only fishy flavors. Maybe that can work for Little, or does she have other issues?
 
A food is considered low phosphorus if it's less than 250 MG/100 kcal. If your cat has kidney insufficiency or is a senior cat (since many seniors have some level of kidney insufficiency that may not be detectable in tests, although there is a new test that catches it much earlier), it's good to feed low phos food. Otherwise, I wouldn't worry about it.
