Re: 5/29 Max AMPS 389+4=327+6=262 Increase+new pen?
i don't think for a moment that Max is a high dose cat. 2.25u isn't much at all. really. not just saying this to make you feel better. If we thought he had some unusual problem, you know we'd tell you. I think he's bouncy.
it doesn't help to compare one cat to another, tina, but if you want to compare to Wendy or Marje's cats, you've got to look at the spreadsheets from their first year. they have worked hard to figure out what to tweak to get their cats into these good cycles. you can't look at the current spreadsheets, because those reflect literally YEARS of their efforts to get their cats regulated.
Elise, in Max's case, i look to his pancreatitis history. In that same PDF, there is a section about pancreatitis and how it makes regulation difficult. He's also got the high blood pressure. It just seems to me that many of the cats that are difficult to regulate (not impossible, but difficult) have a concurrent condition - Irritable bowel, asthma, some kind of virus, pancreatitis, hyperthyroid, the list goes on.
I read your comment from the other night about the vet saying that Max shows signs of being insulin resistant. I'm wondering what exactly he means by that. He doesn't have anything that says to me that he's got iaa (insulin auto-antibodies), cushing's disease or acromegaly. There is the possibility of glucose toxicity (there is a post on it on the NEw to the Group sticky, scroll to the bottom where there are single topic links). The "cure" for that is to get them into better numbers and keep the cat there - which you are trying to do.
I'm also wondering why he is suggesting a lower/no carb food. Sometimes cats here who are on lowest/no carb food are the best at diving. Especially with a bouncy cat, i wouldn't go that direction.
In Max's situation, I still think giving slightly higher carbs to raise his nadirs so you can give slightly more insulin might be helpful. Not sure if you're trying that anymore. I also think Lev is a good insulin and am not sure why the vet is rejecting it without trying it.
I think your new vial of Lantus is working fine - i see a green in there on the 25th after you increased. I'd go ahead and keep using that and give the increase as you planned.
It is frustrating - you have lots of good company. It just takes time and patience, and continuing to try things that might help - that's what i did with punkin.
