Okay everyone before we all get our undies in a bunch.
How is Silver eating? Appetite still good? And what is he testing at BG wise?
Granted the reference range is for humans but since normal for a cat on a human meter and normal for a human are fairly close here is what Jolin's has to say about the circumstances in which it is important to test for them (full article
here)
When should I test for ketones?
Anytime your blood glucose is over 250 mg/dl for two tests in a row.
When you are ill. Often illness, infections, or injuries will cause sudden high blood glucose and this is an especially important time to check for ketones.
When you are planning to exercise and the blood glucose is over 250 mg/dl.
If you are pregnant, you should test for ketones each morning before breakfast and any time the blood glucose is over 250 mg/dl.
While I would grab another test as soon as possible given Silver's readings I really suspect it is just you waited too long to read the strip as they will darken over time
