Good morning. Just took a quick look at last night's thread. This BG is not hypo territory, but is probably why you've been getting such high numbers as it's low enough to cause him to try to "protect" himself.
If you're preparing to give him insulin this morning, don't do that yet. Test every 20-30 minutes until he has come up on his own (without food).
If he drops any lower, and you have some wet food with gravy see if he'll eat some of that - mostly gravy, if you can. You don't know where he is normally low in his cycle yet since you've just started home testing. This should be a safe number for him, he's just not used to it yet.
