At 9:09 this morning, Deb & Wink gave you a whole bunch of information on why you wanted to change insulin.
Did you present any of this information to the vet when you talked with her? Did you read and understand that information before talking to your vet?
Here is one more reason:
According to the University of Queensland dosing protocol for NPH types of insulin states " if nadir blood glucose concentration occurs within 3 hours of insulin administration, or blood glucose returns to baseline within 8 hours then change to longer acting insulin (i.e. Glargine, detemir, PZI) "
Your nadirs the last two days have been around +3 and your +6 was up above baseline. Not enough duration with this insulin.
Why you want Lantus, a better insulin for Rags:
1. better chance of remission
2. longer duration
3. cheaper price with savings card
4. less harsh on a cat (i.e. does not plummet the numbers down quickly and shoot them up quickly.
5. avoid DKA (diabetic ketoacidosis)
You will get bouncing numbers on any insulin at first. That is very common. Not a good reason.
I sought back through the posts and some of the things you told us about your vets advice. From that I picked out these reasons why you do not listen to your vet:
1. initial high dose prescribed and sent cat into hypo
2. being told what to do by the receptionist, not a vet
3. when you contacted the vet office about the hypo, was told there was no one around to help you. they were all at lunch
4. after the hypo, told to still keep giving the 5 units of Novolin N 2 x a day
5. you feel they are endangering you kitty by insisting you keep giving him this high dose even though the protocol says " If nadir blood glucose concentration is < 54mg/dl (3mmol/L) then Dose should be reduced by 50%"
If you go back and reread through your posts, you can probably come up with some more reasons than I found.
By the way, the quotes in here are from the
University of Queensland Dosing protocol for cats on lente or NPH insulin. Here is the link again:
http://www.uq.edu.au/ccah/docs/diabetesinfo/link2.pdf This protocol is dated 2009 so is as current as I could find.
I would suggest that you open this link and print this out and give the copy to your vet. It would be a good idea to print a second copy for your diabetes quick reference information folder.
Trying to 'arm you with information'.
