Thank-you Ry and Julia.
Jinx currently weighs 16.5lbs. Three months ago, he weighed 21lbs. Unfortunately, I didn't notice the loss until it was at 4lbs. That's when I brought him in to the vet at which time he was diagnosed. He is a large-framed Applehead Siamese but his ideal weight is probably somewhere between 12-14lbs.
Julia, I updated my signature block with a spreadsheet for the glucose curve I took the other day and BG readings I just took within the past 12 hours or so. I know the recommendation is to get him on 1u and I'm leaning towards starting that tonight. When I talked to my vet yesterday, he recommended bumping him up to 3u based on the high readings on his Apr. 30 curve. At that time, he had been on 2u twice daily for a week. Instead of going up a full unit, I increased it by .5u and took 3 readings. I was not expecting to see such a significant drop. I'm going to check his BG again in another hour or so.
Please let me know if you think those numbers further indicate that I should start him off on 1u. Also, considering that's he was on 2u for awhile and now 2.5u, is it ok to drop him down to 1u right away or should it be gradual? Thank-you again. I can't emphasize how much I appreciate all of you help.
Yes,
please drop down to 1u, twice a day. Especially since you're changing his diet! You may not think that going from 14%ish carbs down to 3-5% carbs might make a difference, but it most certainly can make a huge difference in insulin need, especially considering the source of the carbs in the M/D. It is possible that 1u is not enough, but we have no way of knowing this until we test it for a few days. That's why we gradually increase the dose in .25u-.5u increments according to the protocol. Again,
I would not listen to your vet's dosing advice. He has already given you dangerous advice that could have killed your cat. Did he provide the dosing information for you that he used to determine his starting dose? I really bet you he won't because based on what you told me I think he made an error with the starting dose formula and multiplied .25u per
lb of actual weight instead of .25u per
kg of ideal weight like he was supposed to. That's straight up carelessness.
As explained earlier, too high a dose can keep numbers just as high as too low a dose. The only way to insure that you hit your cat's ideal dose is to start at the beginning of the dosing ladder. Bandit is also an Applehead Siamese, and his ideal weight is 13-14 lbs. That's average for a male traditional Siamese, so I'm guessing Jinx should about the same based on what you've described. Bandit was also 21 lbs and obese at one point, so he and Jinx sound strikingly similar! Bandit never needed more than 1u the entire time he was on insulin the first time (he was on it for about a year), and he never needed more than 1.25u the second time (he was on it for about a month).
So based on his ideal weight, Jinx's starting dose should have been 1.25u (12 lbs=5.4kg x .25u). We usually round that starting dose down to 1u, because most cats on a low carb diet never need much more than that. Like I said, if you start out
above the right dose, you've already missed the spot where the insulin is going to most effectively lower his blood sugar. Overdosing is dangerous and counterproductive. Lantus is a depot insulin, which means it needs time and consistent dosing in order to effectively lower blood glucose. So if you're overdosing and then skipping shots because his BG is too low, you're not going to get anywhere. You must come
underneath the right dose in order to adequately control his blood glucose. That's why 1u is a good place to begin. You should
always err on the side of the lower dose. I understand that those high numbers seem scary, but high blood sugar can kills slowly over a long period of time, and low blood sugar can kill in a second.
Control is the key word here...managing his diabetes and getting him into remission isn't about
lowering his blood glucose, it's about
controlling it. And that takes time. Like Ry said, this is not a sprint--it's a marathon. He will be high for a while, until he settles on the right dose and then you'll see improvement. But you can't rush the process by starting high and then raising the dose too quickly without enough data, like you're doing. Or you'll get nowhere.
Extra lbs can keep BG slightly higher than you'd like, so he really should slowly lose the rest of his extra weight. However, when a cat has clinical diabetes you don't want to restrict food while his diabetes is uncontrolled. If you can, I would feed as much as he wants of a high protein, low fat, low carb food, as that will best help him lose weight without having to restrict his calories. Once his BG gets under control, then you can worry about portioning so that he
loses the weight safely and healthily. I would highly recommend Merrick's Cowboy Cookout, Merrick's Surf and Turf, and Merrick's Grammy's Pot Pie. They are all very high protein, low fat, and lower carb (the Grammy's is 8% carbs which is a tad higher than some people like, but Bandit handles them fine. You just might want to keep an eye out on that one). Bandit has had outstanding success on these foods losing fat, gaining muscle, and maintaining a healthy weight.

And I hope none of that comes off as harsh, because you ARE doing an amazing job educating yourself and helping out Jinx! If you dose as recommended by the Queensland protocol (and you can get lots of advice and help with that here:
http://felinediabetes.com/FDMB/viewforum.php?f=9), and you feed a low carb canned diet, Jinx has an 84% chance of remission. When proper treatment and dosing is started close to diagnosis, and there are no complicating secondary conditions, that number goes up to nearly 100%.
