Hello and welcome to you and to Matilda.

For 6 years Matilda's diabetes has been under excellent control. At the end of last year she was diagnosed with an over active thyroid and is now on 5mg Felimazole twice daily.
...Her insulin has been increased from 2 units of caninsulin twice daily to 4 units. This has made no difference.
Her fructosomine level now reads good which it is not. I have tested her urine for glucose and that reads the highest.
The fact that Matilda's fructosamine test was "good" and yet her urine glucose test was "the highest" suggests to me that Matilda's blood glucose levels may be fluctuating.
A fructosamine test gives a sort of average blood glucose level over the preceeding couple of weeks.
A urine glucose test shows how much glucose is being excreted in the urine (since the cat last peed).
So, I'm just
wondering if your urine test just happened to be at a time when her glucose was high. But
maybe it's the case that her glucose isn't
always high..?
There are lots of reasons for blood glucose levels to fluctuate. And the hyperthyroid may be causing fluctuations.
Other things that commonly cause increases in blood glucose include:
Infection (dental and urinary tract infections are common).
Diet (higher carb foods increase glucose levels, lower carb foods can reduce glucose levels.)
Too much insulin. When the insulin dose is too high this can cause the blood glucose to plummet, which in turn can trigger the liver to release glucose and counter-regulatory hormones into the system. It's a protection measure, the aim of which is to raise the blood glucose level and
keep it raised for a time. Sometimes the care-giver assumes the blood glucose is always high, because they're not aware of the times when the blood glucose is low.
What are you feeding Matilda at the moment? Have there been any changes to her diet?
If you could consider learning to test Matilda's blood glucose at home that could give you tremendous insights into what is going on with her.
Hometesting isn't that hard to learn and shouldn't hurt Matilda.
Most of us use glucose meters made for humans. And testing basically involves pricking the outer edge of the kitty's ear to get a droplet of blood; transferring that droplet onto a test strip in a glucose meter; waiting for the meter to count down and give a result; and rewarding said kitty with a treat or a cuddle. cat_pet_icon
Here is a link to a page of pics and basic info about 'hometesting' a cat. But do please ask any and all questions you want to.
