    Hi all,

    so the fluid therapy works, I've been upping Galaxy's SQF to 5 times a day, and he's responding well, so much so that this morning at +11 he was 11.5 (yellow). I was at sixes and sevens dose-wise, but I gave a slim 10 anyway after stalling some and feeding. It being bank holiday Monday I felt safe and knew I was going to be around if the SHTF. So, we're at 2.5 at plus 6. he didn't display any symptoms whatsoever though! probably caught it just in time. Gave Kaminox (sugar-infused Potassium and B12 supplement I complained about earlier, but comes handy in hypo emergency). Tomorrow I have to go back to work and in no way can I come home at lunchtime to check.

    How does anyone think I should adjust the dose tonight and tomorrow morning? I mean, I get goosebumps at seeing these low numbers (yellow preshot?!?!), but it also baffles me as to what dose to give? I've looked around among high dose cat spreadsheets on the forum, but ECID.

    I put the 911 because I need information as soon as possible so I can make an informed decision tomorrow morning. Thank you :nailbiting:

    Hi Edy - I'll answer after lunch. You're doing a great job, and you are keeping him safe.
    @JanetNJ also has a similar situation where she can't come home at lunch.

    Direct advice, then discussion. Open to advice from others.

    I would dose on a sliding scale since PZI is a non-depot insulin, and the nadirs appear to be at +6 hrs.
    preshot -> dose
    400 -> 10.0 or back to 9.0
    300-400 -> 9.0 (10% reduction)
    250-300 -> 8.0 (20% reduction), etc
    200-250 -> 5.0 or 6.0
    under 200 -> no dose

    The problem with this advice is lack of data. Galaxy just recently starting giving low numbers. And there are not many test points. One thing is real clear to you now, the importance of preshot tests. If the preshot is 200, and you dosed 10.0 then you would now predict that Galaxy would go to at least 100, or below. Kittehs do not always exhibit symptoms at low BG until the very dire low values such as US. 20 - 30, or lower.

    Meal and feeding consistency is important. Since you won't be home tomorrow, I would be sure that Galaxy has plenty of food available, for all days you are not home. Let's say he goes low. He could eat some food to offset the low BG.

    Doing a "skinny 10.0 dose" is not effective. The skinny and fat doses are more effective at 1.0-3.0 units. For the 10.0, you need to take a percentage off, for the decrease to be noticeable. For example, 5% of 10.0 is 0.5 (a 1/2 unit) -> resulting in 9.5.

    Another issue we have, is that Galaxy seems to be responding now. Could be Acro tumor fluctuation or breakthru of insulin resistance.

    In summary, to be safe I would probably go to a 20% reduction. And if Galaxy has low preshot values like 150-250, then even a further reduction. More testing, including evening post-shot values would be really helpful to establish Galaxy's pattern.

    Look at JanetNJ's chart for C.C. - a sliding scale on a bouncy cat

    I've not dealt with acro but rather IAA which while a challenge not quite the same. I also used a depot insulin.

    I've been accused of being too conservative but if I were you, given that low today, I'd back off tonight by 25% (down to 7.5u) and see what he does and then make a decision about tomorrow AM depending on tonight's cycle and of course AMPS tomorrow. I'd definitely get some mid cycle tests in tonight even if only a before bed test if that's all you can manage.

    I'm pretty conservative too. That is probably good advice to go to a 75% dose = 7.5 units.

    Then you can build the dose back up after we see how Galaxy is responding.

    I think it's definitely that latter i.e. resistance breakthrough. I've been told on this forum before that it happens, one just has to be patient, and that nobody believes it first but it is true, the slow increases will eventually break the resistance. I think that's what happened here.
    Yes, I was going to test before going to bed tonight.

    Thank you for the advice, really appreciate it.

    I wonder if the human meter (SD code free) is giving me false results. I read somewhere that human meters are calibrated, well, obviously for human blood, and that the sugar in human blood is actually more in the plasma rather than in the blood cells (or the other way around, can't remember), but in feline blood it's the opposite, and that's why we get lower results with the human meter. And with me giving so much SQF (100+ ml a day), that surely dilutes the blood and the sugar in it, so these results might actually be a lot more off the readings I would get with the AT2 than we think? That is disconcerting. But then some say that it's the trend we need to look at, and that as long as it's under 15 (mmol) i.e. renal threshold, it is no biggie?
    So this is why I am going to get me another lot of AT2 strips, dunno, I'll ask my other half to get them for my birthday lol...

    Oooh, BTW, I had already given him the dose tonight before I saw your responses. But JeffJ, thank you for that reference you put about the numbers (how much to shoot when)

    Your hypothesis is logical and has merit. Cat's carry more glucose in their plasma than do humans so "diluting" the blood by having them well hydrated could effect readings. It's logical to assume that the AT2 readings would like wise be affected but just how much difference between human and AT2 meter readings could be attributed to the level of hydration is anybody's guess.

    Having given a full dose tonight after that low today, I think it's safe to assume some of that PMPS is probably from bouncing. A low can make kitty a little more sensitive to insulin so it would be a good idea to get an extra test or 2 in tonight just to be on the safe side.

    Please monitor him close tonight. If he broke through some resistance, then he could go low tonight. He has definitely earned a dose reduction. This is the time to be conservative with dosing. You can always go to a lower base value like dose=7.5 and build it back up. We do not want to see you lose Galaxy to a hypo event.

    Most of the people on the forum are using human meters. Freestyle meters seem popular. Yes, they do give lower results. I always used Alphatrak2 with strips for human meters. Typically strips were Freestyle Lite or Insulinx. And I got the strips off of Ebay. So that is an alternative if you want to continue using the AT meter. Typically I could get a deal for $0.33/strip.

    One last request....can you please take the "911" off your post title now? It always sends us into a bit of panic and I think you and Galaxy are OK now. Thanks! :)

    when you can't be there to test, definitely err on the side of caution. I've had a few instances where I had to drive 30 home from work, test, and quickly drive 30 back. man was I cutting it close. hahahahaha.

    Acro makes it hard to judge. my cat was really high for a WHILE. and only in the past 6 weeks or so is down to better numbers. for her the breakthrough dose was like 13... at the moment she's down to around 9ish... but I do adjust a bit depending on the preshot and whether or not I can be home. I'm home in the summer (teacher) so it's been so much less stressful. only have a week left! ughhhhhh...

    Hi Amy
    I don't have any special advice for you tonight. It looks like Galaxy is bouncing around. Definitely a challenge to dose. With luck, maybe his tumor will settle down a bit and respond to the ~10.0 dose. If not, then another small dose increase. I hope Galaxy can achieve some more blue numbers this week.

    Hi Amy - Galaxy is looking good. It is so nice to see some good blue and green nadirs on his chart. With continued low nadirs and B12, we can hope the neuropathy will slowly start to dissipate. Great job on the keeping your kitteh healthy.:bighug::bighug::bighug:

    WHOA! Galaxy is looking regulated the past two weeks. That is just stunning. Kudos to you for keeping up with it, and getting the mid-day nadirs. I suppose you are coming home at lunch for them.

    That full testing during his cycles really shows the effectiveness of the dose. Yay for Galaxy.:bighug::bighug::bighug:

    Jeffj thank you so much for your encouraging words. Yes we have made awesome progress. He's a lot perkier and got back into the habit of sleeping on the bed at our feet like he used to! Hadn't done that in the past 6-8 months. However, we keep getting these red numbers every third morning or so, I think that's either his pancreas flaring up or his acromegaly. THe night beforethe red numbers he always feels like dead weight, very quiet, like he's getting ready to die or like he's in pain,I can't tell. Either way, he still bounces back, amazingly.
    And you know what I think is making the difference here? The amount of subcutaneous fluid I give him every day - 100 ml!

    You bet Amy. It makes me real happy to see the history of a diabetic challenged cat get better over time. In the past, Galaxy had those regular black numbers all over his chart. And now you have him in much lower numbers in general.

    Some kittehs just bounce around. Leo did. And many other cats on the forum as well, such as JanetNJ's C.C.. You are probably right, that the subq fluid is helping him. Whatever you are doing - you are doing it right. I just updated Theresa about Galaxy, and she is happy to hear that he is doing better too.:bighug::bighug::bighug:

    Hi Amy - checking in again. I see some VERY LOW numbers on Galaxy's chart. And I looked through the health notes.

    Low lime-green numbers such as UK 1.5 or 1.9 can be very dangerous. The 1.5 from September 9 is dangerous. Such low numbers means there is generally insufficient glucose for the body's cells to process. Any lower than this, and permanent damage or death can occur. If the cat body does not get enough glucose, cells start dying. Please be careful. Some cats do not exhibit hypo symptoms until they cross a low sugar threshold. Each cat can be different.

    If you have dosing questions, please post them. It seems from your notes that you may think that 2/3 of an existing dose will only affect Galaxy by 2/3 of his previous numbers. Insulin doses don't really have that linear effect. Perhaps I have mis-read your notes.

    My general advice, whenever you hit a lime green number, you should reduce the dose. The nadirs on Sept 11 and Sept 12 look real good. Perhaps Galaxy likes doses of 6.0 or 7.0 now. I know how challenging this can be. You are doing a good job with Galaxy. I hope his neuropathy gets better over time.:bighug::bighug::bighug:

    Hi JeffJ,

    I am considering skipping tonights dose altogether - depending on how low he is at +12. He seems to hold the morning dose for a lot longer than the eve, and i have a feeling that every night he gets dangerously low. This has to stop i agree. I think i need to give him less in the morning, so the am and pm preshot numbers sort of even themselves out. Less, even if he's a bit high. That would bring up his pmps higher so that i can give him a dose closer to what i need to give him in the morning to bring him down into blue at least.

    Hi Edy - with Prozinc being an "in and out" insulin, it should have much lasting effects past the 12 hour mark. However, Galaxy might somehow have slow absorption. His chart sure shows low numbers after low PMPS doses.

    If Galaxy does have Acromegaly, this could be a bouncy tumor. I agree with you that a lower AM dose is probably safer. Then maybe you can level out the doses for him. You are keeping him safe, and that is the main goal.:bighug::bighug::bighug:

    The whole situation is MUCH better than the May-August numbers. Now Galaxy is probably feeling much better, out of those blacks. And you can see the incredible value of pretests and nadirs. One of your WellBeing notes is very correct
    ...to think that the vet told me to stick with 9.5 am and pm, and not to test!!! He'd be dead by now.
