Sorry I missed you Sandy.
I am going to leave you with some parting advice for the next time this happens as I see this is not the first time Felix has had a low number at night.
You have 4 choices when you see a low number at pre-shot time:
1. Don't feed and wait 30 mins, then take another BG reading and see if it's going up or down. Then wait another 30 mins (don't feed yet) and repeat the BG to see if it's going up or down.
a. If it's going up, then you know to go ahead and give insulin.
b. If it's going down, you may want to skip. Especially if you don't have the ability to stay up and get more BG readings throughout the night.
2. You could go ahead and give the regular insulin dose but, once again, you'll need to stay up and retest every hour or so to make sure kitty is doing ok.
3. You could give a half dose of what you're normally giving (recommended by most people on this board). This way Felix doesn't miss a whole dose of insulin and his body is getting something to work with even though it's less than usual.
4. You can skip the dose all together.
Hope that helps. I'll try to keep an eye out for your posts so that I can help in the future right as you are posting.
