Hi rbrumbaugh,
Welcome to the forum. Like you, I'm pretty new to this. I completely understand your stress, and wanting to do right by your kitty. ~hugs~ As I figured out today, testing is crucial!
See here:

And this is my original thread-you'll see I had some of the same concerns and questions that you have.
viewtopic.php?f=28&t=127242
From having dogs and using dogfoodadvisory.com I was under the impression that a good quality food couldn't be bought at a grocery store. Also, I knew raw feeding was best, but didn't feel I was going to be good enough at it to do it properly.
When my cat was diagnosed, his number was 555. And we were prescribed 2 units, twice a day. The very first time we successfully tested him (I gave him a shot in the morning, and he was tested later that night), he tested at 195. Being at the vet can really cause their number to go up.
What I figured out today is-being both high and low are bad, but being high is safer. This morning if I hadn't tested him (he was at 38) I probably would have killed him with that dose of insulin.
We've decided to lower his insulin amount down to 1.5 units twice a day. I think he'll do better at 1, but I'm worried it's too drastic of a change for now...so we'll take it slow.
There is a TON of information on this site. LOTS of resources. It can kind of run together once you start reading, and it may cause you to have questions. There's nothing wrong with that-in fact- it's awesome. It'll help you ask better questions.
The way that you figure outwhat the percentage of carbs are in a food is by doing this math:
100-(protein+fat+moisture+ash)
I'd start with that, and then go with a food you're comfortable with...and that your cat likes. And then, when you're ready-looking at that list of foods that is provided. Every cat is different, every situation is different and sometimes you can't do "the best". You can only do what you can do, and you shouldn't be faulted for that.
I really want to reiterate what has already been said about dosing and feeding a different food. I thought I was doing both slow enough, and this morning I found out I was wrong (we'd moved our cats completely off of the dry food). Based on the calculations given on this board, my vet prescribed too much insulin at each dose. You really have to be careful to find a balance that works for you. If I were in your shoes...and as a side note, I have no business telling you what to do, I'm not a vet or a professional, and I really don't have that much knowledge about all of this, as I'm sure you can tell...I'd switch my cat to canned food and keep monitoring his levels...before giving any more insulin. I've read that changing food can lower it by up to 100. Doing that, plus removing the stress of your vet...might put your kitty at normal/acceptable numbers. It should also be noted that from what I understand it is not a good idea to just stop the insulin altogether. You've got to wean them off to do it safely...so again, find your balance.
Also, if you have other cats, you may want to switch their diet now to canned food...so that in the long run you can hopefully avoid them becoming diabetic.
Best of luck to you!
