I think you should research more. I know that cats can come off of being diabetics, dogs haven't proven thus far to be able to.. I have a diabetic dog.
The thing that worrys me is why you are asking.. Love is love .. You have to do what you have to do.
Whilst I am lucky 6.30am and 6.30pm, some "people" and "animals" require three shots per day which means 12am.
I hope you are standing by her and I encourage you to learn more about it to help her ease the tension and fear.. At 55 it is difficult to deal with something like that, needles and checking the levels with more "needles"..
Take care.
