It's only my 3rd day of testing BG, and my cats 6th day of caninsulin 2IU.

the last 2.5 days he has only <4gram carb fancy feast, and raw meat.

I'm really confused about the patterns in the numbers he is getting.

Thank you!

His preshot yesterday was better. What is confusing you specifically?

Do you feel he's not eating enough?
 
Natasha I would get some more tests in during the PM cycle if you can.

Yesterday MM dropped from 432 to 290 at +3. That is quite a drop and could trigger a bounce. A bounce can happen if the BG drops too fast, drops too low or drops lower than he has been used to in a while. He then dumps stored glucose and regulatory hormones into his system that shoot the BG up high for anything from 1 to 6 cycles. Bouncing is common in newly diagnosed diabetic cats..There is nothing you can do about bounces once they have happened but you can try and stop them by feeding him at around +1 or +1.5 to try and slow the drop. Vetsulin hits quite hard and fast. I would think about swapping over to Lantus.

Also if you get A drop from 432 to 290 in three hours I would test again to see if the BG is dropping lower.

Just not sure how to read if there is any progress with him. He is so visibly unwell when his numbers are high, ie today, just really don't want to miss a beat if there is a way I can help him. I have got the testing and logging down, and I have got his food fixed up, but am completely unsure what to look for in numbers. Thanks! I think he is eating ok, but when his numbers are high its hard to get him to eat anything unfortunately

Ok I will do the PM cycle tonight. I figured it may be some bouncing going on, I had let him graze during the day, he generally will wake up to have food 1.5 hours after his shot, so potentially it is just hitting him too hard despite this. Is lantus longer acting? It is hard watching him in those few hours where it spikes back up, he spends the whole time drinking and is very lethargic. Not sure what to think about the black number this morning either :/ I would guess his numbers have been in the 400's and 500's since around april, which is when I first took him in several times and they blamed his spine (subsequently xray showed perfect spine), I am wondering if this is maybe making him more likely to have the glucose dumps you described? In two more days I am meant to give the vet all my data so they can readdress his dose, I am anticipating them raising it unfortunately. Thank you!
 
Natasha, I would ask to be swapped over to Lantus. It is a much more suitable insulin for cats. It is longer lasting and more gentle and you should see an improvement in numbers with Lantus. Caninsulin is an insulin made for dogs which have a different metabolism to cats.
He is not going to be feeling great if his BGs are dropping 300 in a few hours and then back up again.

The black this morning Is most likely a bounce from lower numbers last night or just the fact that the caninsulin is not lasting long enough and he’s shouting back up high.
This morning he has dropped from 504 to 360 in one hour. That will cause a bounce and will make him feel lousy.
Are you waiting the 1/2 hour after feeding to give the dose? He may need some more food just after you give the dose to slow the drop.

When you go back to the vet I would press for the change over to Lantus.
 
We had a cat a few months ago (Kozmo) who started off on caninsulin and had high numbers. The vet did not want to swap over to Lantus but did relent. It took several days to settle done with the Lantus but then he started to get beautiful numbers and continued to do so. I tried to attach the SS so you could see the difference, but it looks like the share button is deactivated.
 
Hi Natasha,

Here's a graph showing an 'ideal' response of a cat to Caninsulin:

eADcxbPJ2JnNh2lSNJND0_wT4yz4A3Y71CrTNoDJfbWfCTH5m_LSx8bIqc_8XsNxdIIVibS6Rm5BUf37WIe3XPJwQjh4EPhui-nFcwaX6hNFLSfU3NpFvo8wwzZNTc1CUPzdzC--



As you can see from the red curve, it is typical for the blood glucose lowering effect of this insulin to have pretty much petered out by +8 hours after the dose was administered. In essence, for 6 out of every 12 hours the cat's blood glucose sits around about the current preshot range (i.e. insulin is providing no BG lowering benefit). From the available data for Meowmeows it is starting to look as though his response may be quite typical for this insulin.

Even with gradual dose adjustments to bring a kitty into a better range, Caninsulin cats will still typically have this bucket-shaped curve, and although the nadir might get into a good range the likelihood is that the preshots will still be significantly higher. Further attempts to increase the Caninsulin dose tend to result in the nadir getting pushed into dangerous territory but without bringing the PS BGs into a desirable range.

As Bron suggests above, it is very much worth considering a switch to an insulin with a gentler mode of action and greater duration of effect (e.g. Lantus/Basaglar, Prozinc).

Thanks Mogs for posting that graph, it’s great.:bighug:
Prozinc isn’t available in Australia and Levemir is relatively new here so Lantus would be the best option for Natasha, Mogs.
 
@Critter Mom I just looked up online and they were taking submission in 2016 for the use of Prozinc here in Aus. I looked a bit further and it looks like it is possibly available here but I have not heard of anyone using it, but I could be wrong

I would raise the dose to 2.5 and see how he is over the next few days.

I'm going to talk to the vet tomorrow and show all of his numbers and request a longer acting insulin. Waiting the half hour after eating to give the dose, and feeding an hour after too trying to avoid a bounce. Today he ate well through the day, less than 4 carbs and raw, and through the roof again now :( poor thing

Thank you for this detailed response. I asked the vet why the choice was caninsulin and I was told "cats usually respond best but we can change if it isn't suiting him". Given his numbers now, I'm thinking should I be upping the insulin in the mean time, he's so unhappy when it goes back up. I'm going to push for a longer acting insulin regardless, and I test him frequently so I don't believe there is any reason not to switch because I'll know if he is getting too low. That curve would be bearable if his numbers weren't in the 500s maybe..

Thank you!
 
Just spoke to the vet and he said don't raise the dose and he would like to do a curve himself on Thursday. He seemed to think it was OK for the numbers to be as they are, and it's not dangerous until its quite a bit higher than it is.. So not sure what to think :/
 
There is no point in doing the curve at the vets if you are doing them at home. It’s a waste of time and money and MM will be stressed and the numbers will probably be high.
Maybe he doesn’t know Lantus very well..
While the red numbers won’t hurt him short term, it’s unpleasant for MM having high then lower the high numbers over several hours and the longer he is in the high numbers the more insulin resistant he will be. Getting them into more normal numbers early on will give you a better chance at remission.
If your vet won’t swap over to Lantus I would think about looking for a vet who will work with you, not dictate to you. It is perfectly reasonable to ask to swap to Lantas.

What kind of meter are you using? Would you mind adding it to the spreadsheet? There's no point to him doing the curve. Obviously the clinical signs are still not good if he's still drinking excessively and the numbers are still high. Esp if you are using a human meter.... The numbers he would get would be even higher. I disagree and think anytime the cat is spreading a majority of the time in 350+ ranges the potential for developing ketones and organ damage (long term) increases.
 
Hi Natasha,

I also disagree with your vet's view that it's OK for Meowmeows to be spending the whole day in numbers above the renal threshold and approximately half the day in very high hyperglycaemic numbers without, at minimum, revisiting his dose. Meowmeows is, quite understandably, feeling bad when he's running in such a high range. (((Meowmeows)))

Running over the renal threshold all the time (c. 250-290mg/dL on a pet meter according to the online Merck Veterinary Manual) leaves a cat more vulnerable to developing UTIs due to the glucose in the urine. As others have commented, unregulated cats are at risk of developing neuropathy issues and damage to internal organs (including the kidneys, arguably where cats have a particular vulnerability). Also, unregulated cats are more at risk of developing ketosis/DKA.

If your vet won’t swap over to Lantus I would think about looking for a vet who will work with you, not dictate to you.
Agree strongly.

this is what I'm thinking. I'm worried about disagreeing with the vet and having resistance to what I'm asking for, because I do actually like my current vet, and he is quite old and very experienced (instantly knew what was wrong with MM where other vets failed to identify on 4 occasions). I think what I'll do is book him in for a curve for a month from now, and send my vet the spreadsheet to advise in the meantime, then just cancel the at vets curve. He did say to me that we can switch insulins in future if MM doesn't adjust, so I'm wondering if the vet is just thinking it's too early to say caninsulin is ineffective? (it's only been a week). If it doesn't start to balance out soon I'll ask for the switch. I wouldn't mind the cansulin curve if the numbers were more reasonable and I could effectively offset the bounces, but if it continues like this then definitely not. Thank you for your advice, I need to more confidently pursue what's in my cats best interests for quality of life

They actually sent me the wrong meter, so I'm using a human meter called "caresens dual". I agree there is little point doing a curve, I suspect maybe the vet meant we'll wait until Thursday to do a curve (a week since starting) where my cat was booked in, but he might be fine with me doing it myself I'm going to call them shortly. and I agree wholeheartedly, I'm seeing a daily increase of hind leg weakness, his coat deteriorating, and excessive thirst, he isn't in good shape at all, and at minimum a lot of stress on his organs and like you say potential for ketones and permanent damage

Thanks mogs. Exactly, I need to speak to my vet again to go over this, in retrospect maybe he meant he doesn't feel he is in exact immediate danger, and just wants to give it a week before adjusting the dose /switching insulin? I definitely won't leave it more than another few days without pressing the vet to make a call on dose at minimum. The hind leg weakness really concerns me. and I think neuropathy is definitely is a factor for him. Last tested at the vet he had high levels of glucose in the urine, just seems cruel to leave him surfing these kinds of numbers :(

Thank you so much for your advice and direction.

I mucked up my spreadsheet because I made a different one for my vet, just fixing it now. But would someone be able to have a look at this picture and advise?

Spoke to my vet who upped the dose, said we can switch insulin if he isn't leveling out within the month. I'm really confused by what's going on here :/

Thanks everyone!
