ARGH. i just wrote a post out and it didn't post! so annoying.
let's see - basically i said it's good that you increased the dose, and the increase is in line with the protocol but it's a big increase. that's 50% more insulin that she's getting, so i want to encourage you to get in more tests to make sure she doesn't tank with it.
also, i fed punkin and anya some of Newman's Own because punkin needed low phosphorus for his kidneys, but with Mom Mom's numbers being so high, i would stick to the Fancy Feast you were giving her before. Those run in the 4-5% range. Newman's adds rice to the food and the rice is a source of carbs, which Mom Mom definitely doesn't need in her regular meals.
Hope you're having a good day!
