Checked in a bit earlier and saw that 61! WOW! At that time I really thought he would bounce up higher so seeing that 152 now is really a very pleasant surprise. Now that said, as wonderful as those numbers are, I know exactly what you are feeling when you can't be there to monitor closely.
Stalling - If you test Bear and his BG is below 200 at pre-shot, don't feed him and wait 15-20 minutes and test again to see if he is rising on his own without any food in the picture. You can stall up to an hour total or 3 stalls keeping in mind what that stalling is going to do to your schedule going forward. This is when you have to balance out both Bear's needs with what you are able to do.
Given the cycle he's had so far, I don't see the need for any increase in his insulin. Right now his cycle is beautiful. Now we just have to see what he does between +10 and pre-shot.
OHOHOHOH! just saw your last post ...well I guess I'll eat my words now! Well some of them. He has bounced and he's quite the trampoline master. I still wouldn't increase his dose. He's bouncing from that drop of 171 points. Better to let him run a bit flatter to bring those pre-shots down so I think I'd hold the dose for now. I might even try dropping it to 1.5u as long as he is still negative for ketones to see if that keeps the drop a little more moderate as that should bring down the pre-shot numbers.
The change from high carb to a mix of high and low which would be equivalent to medium probably had something to do with those numbers. With the DKA you don't want kitty going low because it's hard to get enough food into them to keep them from crashing. As long as Bear is eating, that is not such a concern. But if you won't be able to monitor as closely in the next week or so, then keeping him at reasonable levels is still an important consideration.
Let's see what he does at pre-shot because he's been known to pull some fast ones on us!
