Hi Lefties Rule
welcome to the forum.
As 14+ as posted for you the stickied thread at the top of the cat health forum is all about CRF.
How is Rusebud feeling overall physically and emotionally? Showing any symptoms?
Do you have Rosebud's lab values with refernce ranges?
Is she being treated with diet alone at this point or do you have her on fluids, antacids, or supplements?
To get to your food question what are you currently feeding and what were you feeding previously? Is Rosebud on canned only? If not what dry is she eating? Switching to a canned only will be the way to go once you get her eating reliably.
What pet food stores are available to you? A smaller local supply store that carries holistic foods will have a better selection of these foods or may be able to order in for you.
Here is a variety of good holistic low phos foods for you to start. Wellness, Innove, Evo are pate for the others check the label on the can
