So Jude’s dental was 9 months ago and needs another! And you use those cloth finger wipes on his teeth daily? I am sorry about his FIC. How do you manage that? It looks like it can be idiopathic. I know pred can cause diabetes but if you already have diabetes and pred can reduce inflammation from other things I wonder if it can be appropriate course of action.
I am, in fact, NOT using those finger wipes daily because I'm a bad mommy, and I forget to do their teeth daily (bad mommy). I did just purchase a toothpaste that is supposed to help with the gums; I'll TRY to remember to use it going forward, once I get Jude through this inappetence issue. The vet didn't seem too worried about twice a year dentals; he said diabetic cats have bad teeth, and it's just a common issue he runs into with them.
Jude has both UTIs and FIC flares. Every time he has a flare, which has been about four times this year, I have to take him to the vet for a cysto/culture/sensitivity to the tune of ~$400 per test. But, it's important to try to determine what we are dealing with: UTI, which gets an ab, or FIC, which doesn't. The very strange thing is this: the times he hasn't had a bacteria (the test came back negative yesterday), his numbers continue to rise gradually, like they would if an infection were present, and while the vet is waiting for the culture/sensitivty to come back they start him on an ab, which almost immediately begins to result in lower bg numbers. So, the vet is somewhat confused about this, and said it's possible that the test is not picking up some infection. It is also completely possible that this is simply FIC, which flares are often one week in duration, and the ab action could simply be coinciding with the waning of the FIC flare

So last Monday, when he reached the 300s, the vet did a cysto/culture/sensitivity and put him on two weeks of Clavamox--one week longer than normal this time to see if we can knock out any recurring infection, if that is, in fact, the cause of the rising numbers. Sadly, the Clavamox is giving Jude an upset tummy and inappetence, so we're battling with that and with giving him an anti-nausea med and an appetite stimulant. In terms of ongoing, daily treatment of the FIC issue, he takes supplements to try to keep the inflammation down in the bladder, we use Feliway dispensers, I am in the process of moving him to a non-clumping litter, and when he has a flare, he goes on Gaba and Prozacin.

I'd like to say it's exhausting, but then I think of others on this forum who have MUCH more complicated issues, and I tell myself to shush.
