I think it might have been @Wendy&Neko who wrote this in one of the many posts I have been reading, that large cats do better on Levemir? Catman has been 16 to 17 lbs since he was a year old! He's the one who's been super bouncy and is now showing signs of neuropathy. Just trying to see if we're on the right path. (I'm not sharing my spreadsheet openly because either a bot or a person is using it, no matter where I put it or how I rename it, to tunnel in, activate my phone's keyboard and make changes like formatting or adding periods after the numbers or an inserting emojis. I did a factory reset and it still happened. I am working with Google on figuring out how. For now if anybody wants to see my spreadsheet I will either add you or upload screenshots.)
Tigger is a large cat, he has also been very large from a young age. Not overweight, just big. Currently, he is 18 pounds. 20 at his heaviest. We recently got on levemir. I don't think it's necessarily because of his size we are not responding to other insulins. We have some things to rule out, like acro or insulin resistance (iaa). But if you take a peek at my spreadsheet you can see where we've been so far. However, I wanted to also comment about your spreadsheet. I constantly have issues with mine saying I do not have permission to edit it and I am the creator! I have to make copies all the time and then it works for a while and then gives me issues again. So let me know if you figure anything out!
It's cats who are on larger doses (not size) that we often recommend switch to Levemir. Size of cat doesn't matter when suggesting someone try Levemir. I've also seen small cats with tiny doses do better on it. There isn't a correlation between size of dose and size of cat. With one caveat, cats with acromegaly have excess growth hormone which can cause them to be bigger. A number of those cats need larger doses. Lantus's acid base can sting at higher doses, so we suggest Levemir in those cases.
Just a thought ... are you clicking your signature link when this happens, or always going directly to your google spreadsheets? Mine won't let me edit it if I just click the shared link.
DH and I thought that was it at first, so we created shortcuts to the file directly from sheets onto our home screens. Sometimes we would go in through drive. Ultimately it didn't matter something was changing the permissions in my file and that escalated to editing the file by activating the keyboard on my phone. I've started a separate thread about this under the spreadsheets forum here https://www.felinediabetes.com/FDMB/threads/ss-being-hacked-on-my-phone.235304/
