Choy-Foong just gave me Meowzi's azodyl last week, Melissa. It is highly recommended on the CRF sites, and when Scruffy's oncologist was trying to find something that would help lower his phosphorus/calcium levels, the IM vets at the hospital told him to tell me to use it. I don't know what makes it appropriate for that problem.
It's a probiotic. Comes in a capsule, but Choy-Foong said that she gave it by pouring out the powder and mixing it with a little baby food. There were a couple of letters on the CRF site from people who said that they gave azodyl capsules to their cats and 12 hours later, the capsules showed up again in barf, seemingly untouched by feline digestion. (It's intended to only be available to the body after it's in the intestines...)
Scruffy is NOT enthused about azodyl.
Did anyone tell you to get Aluminum Hydroxide dried gel powder? Choy-Foong gave me that, too; it comes from Thriving Pets.com. You mix it into their food - it's a phosphorus binder. Dosage is determined, by the Dr. Nagode formula, by the phosphorus level of the cat. (need bloodwork to know that.) Supposedly tasteless and odorless. Scruffy's willing to eat food with AH in it. Not that it's done a bit of good, unfortunately.
There's also a list of all the assorted CRF/D foods on Tanya's site. That Solid Gold cat food we talked about, with the whole mess of different meats in it - is almost as low in phosphorus as the Purina NF canned food for renal failure (.55% to .52%). And it's a pate - Scruffy - after all these years of eating canned, no gravy, diabetic-appropriate foods, really isn't into the gravy/hunks of meaty stuff that seems to be how most lower phosphorus food come.
Isn't Epakatin for anemia? Or do I have the name confused with something else? I would think you'd need bloodwork and dosage instructions, etc. from a vet, if it is.
I take CoQ10, and my kidneys are functional. *shrugs shoulders*
