Your posts are coming through. I (and a couple other people) responded to your post about your first successful test. You also asked about low phosphorus foods, and there were a couple of links to lists of foods in the replies in case you haven't seen them yet.
Those numbers are really great! You said in the other thread that she wouldn't eat the M/D after the first day. Unfortunately, that is pretty common. It must taste terrible! My cat Bob did the same thing, and I ended up returning the cans to the vet for a refund. Is it the canned or the dry m/d that you are using? Neither is really great in terms of carbs, and if you can look at the low phosphorus lists and find anything with lower carbs, her numbers would drop even lower.
M/D canned is 14% kcal from carbs, and the dry is 13%. If you can find anything less than 10% on the lists, she'd be better off.
