Hi,
We're going to need more information to go on so we can start really helping you and Louie out.
Your insulin is Lantus, and the vet has him on 3u BID, right?
I saw in an earlier thread that Lori told you about "newbie kits" so you can start hometesting Louie's BG. Have you contacted her about getting one? If so, have you started testing yet?
What sort of BG numbers have you gotten, or has the vet gotten?
Has anyone asked about or showed you where to go in order to set up a spreadsheet?
You've also been trying to transition 5 kitties to wet food.... how is that going?
You said that his numbers are all over the place, but what are they?
Depending on the numbers, it could be that 3 units is too much, in spite of what your vet says, but we need numbers to see if that is the case.
Have you seen signs in Louie that he is doing any better? Less peeing and drinking? Good appetite? Is he moving around okay, any signs of mobility problems?
The more we know, the easier it will be for us to help you out with this. Also, where abouts are you located? There may be another member close by that can suggest a different vet, one that is more familiar with feline diabetes and basically just a nicer person! A vet who gets annoyed by questions is a vet asking to lose a customer. Not cool with me either!
You don't have to figure this out yourself. That's why all of us come here every day. To help people, just like we were helped the day we showed up lost, confused and overwhelmed. You're part of a really great, large, wonderful community now.
Carl
