Hello. My name is Sharon. I am new to the message board. As I said in my introduction, my cat, Sunny, has just been diagnosed with Diabetes. His first shot was last night. I was wondering if there is any wiggle room in the timing of giving insulin or does it have to be 12 hours exactly. I also was curious about the 8 hour glucose test. I'm going to try and do it at home. My understanding is that I will need to prick the very tip of his ear. Is this the best place to get the blood from? The insulin regimen seems to be going ok so far although I have only given him 2 shots. All of this is very overwhelming. My son is very supportive and that helps. I took care of my diabetic husband for many years before he recently passed away. That makes this especially difficult.
