It sounds like it was used in your case to measure her levels during and after a serious illness - with the latter testing showing much better numbers? Am I correct in my understanding? In that case, I can understand the benefits of the testing.

I am not saying the test is not a valuable one. But, for Feeby, I don't think the vet thinks there is much point in testing her at her age, especially since she is not having any health issues aside from the H-T at this time. I personally think he feels that making dietary changes probably won't prolong her life by any measurable amount, and he really isn't a proponent of kidney food diets in terms of their actual overall benefits.

I do know he is up for other ideas I come across, so the H-T forum offered to provide me with some supplements that might be of benefit for Feeby, and I will look into those when they share them with me. As far as the phosphorus binders, I am still on the fence about whether or not to pursue them, even though the H-T forum thinks she should be on some. Another discussion for the vet and me to have somewhere down the line. Ditto for the SDMA.

What therapies did you give Lola?
Just wanted to add little more information about SDMA bloodwork from my own CKD, hyperthyroid kitty experience, in case it helps you, FeebysOwner FeebysOwner . My cat is probably around 9 years old, and she was diagnosed with CKD (IRIS stage II) based on her bloodwork after a period of illness that her vet believes was a CKD "crash". For kidney bloodwork, my vet always includes the SDMA as part of the monitoring. It's not something I even ask for. I do believe her practice uses IDEXX tests and labs as part of their regular diagnostics, and the SDMA test is proprietary to IDEXX. So, for Mumu's most recent bloodwork, her BUN and creatinine levels were quite good, in the middle of normal, but her SDMA was right at 14, the highest end of what is considered normal (her highest reading had been 20). So based on that, the vet is making sure that Mumu keeps drinking her water and other good things for kidney support. Having that SDMA reading is a nice additional piece of information for the vet to monitor for a fuller picture of the CKD progress, I think, but obviously there are other numbers that you and your vet already have also.

Since the two meds you mention above are prescription only, they will be added to my list of discussion items with the vet. Thanks for sharing with me your regimen for Lola! All will be added to my notes about potential treatments/care for Feeby!
In "my days" Fortekor didn't require a prescription... at least, I can't remember I would need it. It seems to me that I would just walk in the pharmacy and asked for it. I might be wrong, though. I see that now I would need it, I just checked.

All the rest are supplements, the Azodyl too is a supplement, and I'm sure supplements don't require a prescription, at least not here, but it might be different in the US.
I also found out that now the Azodyl is available in Europe too. Good to know that.

This information is probably only useful for those who have a cat with a high phosphorus count, like Feeby.

The low phosphorus food search has pretty much been a bust so far. But, I did find a more recent type of phosphorus control being used - niacinamide - a specific form of vitamin B3 that is not a binder but works by blocking the uptake of phosphorus instead. It seems it is starting to be thought of as a good alternative to the binders that have been more commonly used. One of the H-T forum members shared an article with me about it and I thought I would share it with all of you. Disregard the article's headline title that suggests the information is somehow related only to cats on raw food diets.

When I had to deal with the CKD in my cat Lola, one of the supplements I would give daily was a mix of Vitamins B, so the B3 was in the mix. I had read that this complex of Vitamins was good to reduce the absorption of toxins, but now I read that the phosphorus as well can be blocked, so I did a good thing.
I recently learnt that Vitamin B3 in the form of Nicotinamide, along with Chaga Mushroom powder, is suggested in the therapy for FIP during the administration of the GS drugs.

I haven't had the chance to have a full dialog with Feeby's primary vet, but did speak with her back up vet today. Feeby had tests done on Tuesday, and her BUN and Creatinine are increasing. The creatinine now 2.8 from 1.8 a month ago (range 0.6 - 2.4) which from what I can recall actually puts her in the upper range of Stage 2 of kidney disease, per felinecrf.com & IRIS. She could even be in Stage 3 according to IRIS if there were SDMA numbers available. But, the H-T forum members don't seem to think SDMA is all that reliable, and neither does my vet. As a side note, her phosphorus level is down a bit, but not within the range that the H-T forum folks think is more appropriate for her age.

What happens at this point? What do I need to investigate so I can be prepared to ask the right questions of her vet next week?

I guess I am a bit overwhelmed right at this moment, probably need to take a step back, and re-read information from the above referenced web site. I haven't even gone back through this thread to collect information.

I guess I am just kind of lost - none of this should be, nor really is it, a surprise, and yet I feel stunned.

I don't have any answers to your questions but I also talked to Carleton's vet this week regarding how long he can/should stay on the Methimazole. We will have to repeat bloodwork although not yet and check his urine. I go back and forth with my concerns too and the more I read the more questions I have. It sounds like you have a good relationship with your vet and back-up vet so I hope they can offer some guidance for Feeby. 🤗

Thanks. As far as I know the H-T is almost kind of a separate issue anymore. Going through radio-iodine won't resolve the kidney issue - from what I know at this point it wouldn't change or reverse the kidney problems. I just need to better understand when they say H-T masks kidney issues - do they mean that the kidney issues already exist but are hidden in test results because of what H-T does to the numbers. I don't know. I thought I knew more than I feel like I really know.
