Those are all the foods I feed her exactly. So food shouldn't be the problem.
There were a lot of other foods that you list on your SS. I went through, and checked them against the catinfo.org food chart to find the ones that were the lowest carb. If you can try to concentrate on feeding just those I listed, we may find out if it makes a difference in Suki's numbers, feeding only these limited foods.
What I was saying, was to limit the particular foods you feed to only a select few. So for now, no Authority Salmon or Whitefish, no Newman's Turkey, no Hi Tor Neo, no Halo Salmon, none of the others I did not list as the <= 6% carbs. Some of the foods you feed were at the higher end of the <10% carb limit, up around 7% and I thought some of them were even up around 13% carbs.
So try to feed
only the Halo Spot's Pate Chicken, Wellness Grain free Chicken, Wellness Grain free Turkey, Authority Chicken. This will let us test for some carb sensitivity and see if it makes a difference in Suki's numbers.
Believe it or not, it can make a difference in some cats, to lower the carb percent even a few points.
