Re: Newly diagnosed - wrong insulin???

Ah, low potassium can also be a cause of back leg weakness. When cats are peeing a lot potassium is easily lost from the system. It could be worth asking your vet about a potassium supplement. In the UK many folks (with potassium-deficient cats) use drops to put in the cat's food.
Sometimes the back leg weakness in diabetic kitties is caused by neuropathy
and potassium deficiency.
The B vitamin that helps with neuropathy is methyl B12/methylcobalamin.
But the symptoms should also resolve once your cat's blood glucose numbers get into a better range.

[regarding insulin shots]...I have lost confidence & get upset & worried before its due, hoping I don’t mess it up. On a couple occasions I have felt it is wet after the injection.... Since, I have given her a unit more on the next occasion it leaked...
It
can take a little while to feel confident about giving insulin shots. Don't worry, it's early days. (I was needle-phobic and had to practice on oranges at first!)
There are a number of techniques. Some folks pull up a 'tent' of loose skin on the scruff of the neck and then inject though an imaginary door in that tent, parallel to the spine. I give Bert his shot while he's eating on floor and I'm standing next to him, so I pull up some loose skin between my thumb and fingers, and then give the shot almost directly down into the skin I'm holding. (You can 'feel' that the needle has pierced through the skin and gone into a sort of empty space underneath.)
When some of the insulin ends up on the fur instead of inside the cat we call that a 'fur shot' here. And although it can be very
tempting to give more insulin when that happens we always advise against it. The reason is that there is no way of knowing how much insulin actually went into the cat. Therefore, we run the risk of overdosing the insulin if we add more (and too much insulin can cause hypoglycemia.)
However, in Alice's case, because of the high blood glucose levels at the moment, it doesn't look like it has caused harm
yet.
I do fully understand the frustration of seeing your cat in high blood glucose numbers coupled with the realisation of having done a 'fur shot'. It's an uncomfortable feeling. But at least, with Caninsulin, you could consider the option - if you want to - of giving the next shot early... Caninsulin is an 'in and out' insulin (it doesn't build up in the body like some insulins) and it has a fairly short duration. It can be 'done and dusted' in about 8 hours in some cats. (And some folks using Caninsulin do give shots every 8 hours. I did this for a long time (5am, 1pm and 9pm in my case). But not many people have a schedule that can accomodate 'TID' dosing.)

[Re possibility of too much insulin]...Is there a way of knowing this - can this be checked?
We do see some new cats here who are are too high an insulin dose. Sometimes the initial starting dose was just too high. Sometimes the dose was increased too quickly and the appropriate dose was missed.
Typically, we might see high 'flat' numbers, and possibly high numbers that are
continuing to get higher. If the care-giver is only testing before giving the insulin shot - and sees only high numbers - they could be forgiven for thinking that the numbers are always high. But in fact what may be happening is that the insulin is causing the blood glucose to drop too low (or too fast, or both) at some point in a cycle, and then the body is responding to this perceived threat by putting more glucose out into the system (sometimes also with counter-regulatory hormones that will keep the blood glucose high for a time.) We call this 'rebound' or 'bouncing'.
In the test results you've detailed in your post I can't see any evidence
there of low blood glucose results. There was quite a steep blood glucose drop on 17/3, but this doesn't seem to caused a bounce because she still dropped from the following insulin shot. (The following day though her numbers were high and flat (unmoving).
Many folks here enter their cats' blood glucose results onto Google spreadsheets so that everyone here has access to the data if necessary. If you're willing to set one up there are some smart techy people here who could help you with that (I am
not one of them! :lol: )
Seeing the data on a spreadsheet makes it much easier to spot patterns/trends.

...How long should I give the Caninsulin before asking for another insulin do you think?
If the Caninsulin doesn't appear to work for Alice then - unless your vet is pro-active and volunteers to prescribe a different insulin - you'll need to collect enough data to show that it's not working sufficiently well. Some people here have used the data to demonstrate that the Caninsulin only reduces their cat's blood glucose for a very short period during each cycle. Some people have used the data to show that Caninsulin causes very steep blood glucose drops in their cat.
However, Caninsulin does seem to work just fine for some cats. And quite a few cats on this forum have gone into remission while on it. ('Remission' means that the diabetes can be diet-controlled).
