Xuxu is still yo-yoing, but not going quite as high. He hasn't hit 750 for nearly a week. Since that is the meter's limit, who knows how high he has actually been at that number. He is registering in the low 700's or high 600's though. And he is still going quite low on only a .75 dose. Most of the time he is asymptomatic, so I have learned to stop panicking and don't give glucose, just a couple of his fav, Iams kibble. I test in 15 min and if it's on the upswing, I don't worry about it. I have lowered the dose the last couple of days to .5. But I caught him at 49 yesterday because he was lethargic and not eating. I gave him fluids and some glucose (gel from those tubes in drug store for diabetics) and a a couple of kibble. I really knew he wasn't feeling well when he didn't gulp down the kibble. But in 15 min, he was up to 61, so didn't worry. Although in 30 min he did eat the kibble, it wasn't enthusiastic, and he seemed quiet the whole evening. He was up to 612 and started to eat some of his canned food again. Because he goes so low, I didn't give him a pm shot, worried he'd bottom out while I was asleep. This morning, he's down to 572. This has happened a couple of times, his BG lowering without a shot. He didn't eat much though the night. I decided to see what is naturally going on and didn't give his am shot. I saw BJ's response to Mimi and Loki, so perhaps that type of bounce is happening. Anyway, he's acting quite different from the last couple of weeks where he was happy, purring, and eating like there's no tomorrow. The UTI appears to have cleared up. I am checking his ketones while he's not getting a shot.
