I just posted on your other thread for today and am directing everyone to post here. We encourage people to edit their subject line all day long to reflect any questions and to update with test results.
Here's what I put on your other thread:
Just to check some routine things - did you buy his insulin from a regular pharmacy? Are you using u-100 syringes?
As Chris said, some cats need more than others. You've got plenty of data to show that he needs more insulin rather than less. I think I would just stick with the guidelines for SLGS for now, increasing every week. When a kitty gets up to 6u we suggest that s/he is tested for the 2 most common high dose conditions, acromegaly and insulin auto-antibodies. Punkin had acro and got up to 15.5u per shot before we had it treated and his dose started to go down. The most recent research is that 1 in 4 diabetic cats has acromegaly. It's a benign tumor in the pituitary gland. Insulin auto-antibodies is less common, but we see it pretty regularly here. It means that the cat's body has begun making antibodies against the insulin that's being injected. The antibodies bind to the insulin and keep it from being usable by the body for a period of time.
I'm not saying that Lincoln has a high dose condition. I'm just saying that it isn't uncommon for us to see kitties that aren't responding to the usual dose and that need to go up in dose. There is nothing here to say that he is overdosed. From what I can see on his spreadsheet, I don't think he is. I think that it's a matter of going up in dose until his blood sugar levels improves. Every cat has a dose that will move him - it's just a matter of getting to it.
Hang in there Amber. It's hard having a kitty that isn't responding like you'd like them to.
