The most important thing is that she eats. It doesn't matter how perfectly
formulated a special diet is if the cat won't eat it. Sometimes we must
make compromises and choose the lesser of the evils. Several regular
maintenance diets are low in phosphorus but unfortunately most are
acidified- which isn't very good for a renal cat. There are ways to counter
this effect but playing with a formulated diet can be very dangerous unless
you know exactly what you're doing.
If your cat won't eat any of the commercially available kidney diets
(several manufacturers make renal diets), the next best thing is a diet that
contains the lowest phosphorus and sodium you can find.
Best of luck,
