Hi Goeril,
Good to hear you skipped a shot, to get yourself back on schedule and back to your normal sleeping and awake times.
I'm thinking, could it be better to keep him a bit high, like in yellow/top blue in nadir time - then its not this big panic of him dropping too low and all the close monitoring that is then needed - what's your thoughts about this?
Ideally, you don't really want Panter's nadir BG to be above renal threshold, where excess glucose is dumped into the urine. That can result in frequent UTI's (urinary tract infections) but more importantly there will be slow but steady damage to his other organs.
Plus, our diabetic cats rarely cooperate on keeping their BG levels up at nadir. If only they would be so accommodating!
So somewhere above 180-250 mg/dL ( 10-13.8 mmol/L) is too high, above renal threshold for most cats. Each cat is different, and they do not have the same renal threshold. But it takes time to get cats BG's down lower. So don't worry too much about that at this point in time.
I think you have to let Panter be Panter. And not worry too much about his BG levels and what might happen one day in the future. Panter is being a typical cat, and you have to go along with what he is doing.
If he feels trapped, when you try to keep him inside, you'll simply have to let him indulge his wanderlust tendencies. So sometimes you don't get those tests. So sometimes his BG might drop lower at mid-cycle than is ideal. Many cats will naturally seek out food, when they feel their bodies blood glucose drop lower. Panter may come home for a bite to eat when that happens. Panter is too much of a free spirit to keep confined, especially now that late spring is here and summer is just around the corner. Let him wander to his heart's content, and love him when he comes home for those "pick the ticks off" sessions.
You'll probably get off schedule with the shots again. But now you know what to do next time.
I skipped the am shot and I'm starting over at 7 pm. Thinking - I will try to give him a 85g bag/box at +12 after shooting, then a big meal 150g just before nadir closing in +5 - the idea is that he will have some food in his stomach when nadir 'kicks in'), then put out a snack 50g daytime (maybe 100g at night as he is more active) +8, maybe even from +7 (6/7 is the nadir) ...but not too much food here though, then he want show up for his shots... Does this sound like an idea?
Your plan sounds reasonable Goeril.
You know he is going to catch more mice, and dine out at his favorite restaurant on his catches. You do what is possible for you and Panter, not some idealized feeding schedule, such as feeding only every 12 hours, that many vets suggest. I fed Wink 4 times a day, 2 breakfasts, 2 dinners, but he was strictly an indoor cat.
I haven't had a diabetic cat in 3+ years, since Wink died. So no suggestions from me on changes to your suggested feeding schedule.
