not sure if you had a chance yet to read my post above about punkin's SRT. That goes through all the costs that we experienced or anticipated. It also goes through all the details of the SRT, and my thought process in deciding to have it for punkin.
It is a reasonable treatment approach to just give increasing amounts of insulin. That's the option many people choose. You can't achieve remission with acro in the same way a "regular" diabetic cat can heal and become diet-controlled. The tumor can shut down, but it can also turn back on. Even having the SRT isn't a guarantee of remission - some do, some don't. Even if they don't, though, SRT does stop the damage done by excessive growth hormone.
there are no meds successful at treating acro. the only treatment is to deal with the tumor on the pituitary gland - SRT is radiation. There is also a freezing/surgery called Cryohypophysectomy discussed here in this article: "Cryohypophysectomy used in the treatment of a case of feline acromegaly"

I'd encourage you to get a diagnosis first before you go too far down this road. She may or may not have acro. You don't need a specialist unless there is something more going on than "just" acro. A regular vet can prescribe the insulin, as you already are. We can help you with 90% of the rest of it, and you can get specialist help for specific things when you need them. For the overall treatment, though, a regular vet is fine.
Do you have fructosamine tests that confirm that her blood sugar has been really high? I ask that because we do occasionally see someone come in here that is on a high dose, and the blood sugar is high, but the cat is high because the doses were increased too quickly and/or by too big of increments.
I looked back through your previous post that Kay linked (thanks Kay!) When a cat's blood sugar is high, that alone can cause them to be starving, literally. The way we are nourished is that our food is converted to glucose, which then goes into our cells and "feeds" us. That's probably a lousy explanation, but you get the idea. When you measure high glucose in the blood, that means that the energy from the food Baby ate is floating about in her bloodstream and not getting into her cells. Any cat in high numbers will be starving, because they literally are. As the blood sugar comes down, that means the glucose is getting into the cells and feeding her. Her appetite should reduce some as well.
If it doesn't reduce when her blood sugar is in lower numbers, like less than 200, then it becomes more significant than when she's ravenous while in high numbers. Any diabetic cat is ravenous when their blood sugar is high.
When you say that the dose was increased in 1-2 units over a couple of weeks, can you give us the exact info? It makes a difference. Even for a high dose cat with a known acro/iaa condition, on a dose of less than 10u we wouldn't increase by more than 0.5u at a time. The reason this is significant is that if a cat is overdosed, and in danger of hypoglycemia, the cat's liver will put out counter-regulatory hormones & stored sugars to counteract the insulin overdose. Larry's comment about her curve showing a movement, and therefore it might not be from an overdose is probably right. Usually if they are overdosed it will usually be a constant high. But it would be helpful to see more data.
Blood sugar tests are so important. As we get data on a cat, it's just like putting in the pieces on a jigsaw puzzle. Data doesn't lie - and experienced people can tell a lot from looking at blood sugar tests. If you can look
here the second link down will help you create a spreadsheet. It's not as daunting as that might sound. There are great directions there. Any previous data you have, or can get from the vet on her blood sugar at diagnosis, dose she started at and any tests, the dose changes, etc., just as best as you can recreate it would be hugely helpful to us in figuring out what she might have going on.
To help her ears, get some Neosporin ointment with pain relief. The stuff is amazing. I slathered it on punkin's ears every night and they would look like new in the morning. If i had to poke him a lot during one day, i'd put more on. You have to wipe off the excess before you test, though, or it will goo up your strip.
You're in the right spot now :YMHUG: We are all volunteers, but live/breathe feline diabetes 24/7. we'll give you a hand - and we're free.

We all volunteer because others taught us and we know there isn't much help out there for diabetic cats.

ps - what can we call you?
