dosing and sugar level help

hei. my cat is on 2 unit moring and 1.5 units in the evening.
in the morning his number is about 22 mmol/l. if on 1.5 dose he will be about 15mmol/l after 6 hours ,on 2 dose he went down to 2mmol/l after 6 hours.
but after the 12 hours he will be back at 22mmol/l. or higher. with 2 dose he will bounce up to 25mmol/l.
he is on a no carb diet.
vet says try 2 dose longer, but am afraid of hypo.
not sure what to do.

 

Hi Trude, welcome. Sounds like you are home testing? If you would set up our spreadsheet it will help us help you see what's going on. If you need help, just ask and someone will do it for you.

In the meantime I'll tag @JanetNJ and @Kris & Teasel as they have experience with your insulin.
