Have you seen this excerpt from the Basics Sticky:
'What is Regulation?':
There are different definitions of regulation. As hometesting becomes more common, we've been getting a better understanding of what cats and their humans might be capable of. Janet & Fitzgerald propose the following "regulation continuum":
Not treated - blood glucose typically above 300 mg/dl (16.7 mmol/L), poor clinical signs
Treated, but not regulated - often above 300 (16.7) and rarely near 100 (5.6), poor clinical signs
Regulated - generally below 300 (16.7) with glucose nadir near 100 (5.6), good clinical signs, no hypoglycemia
Well regulated - generally below 200-250 (11.1-13.9) and often near 100 (5.6), no hypoglycemia
Tightly regulated - generally below 150 (8.3) and usually in the 60-120 (3.3-6.7) range, no hypoglycemia, still receiving insulin
Normalized - 60-120 (3.3-6.7) except perhaps directly after meals -- usually not receiving insulin
As Kit said, one of the "healthy" indicators is under renal threshold. That differs with each cat and also on each meter. For my Cleo, her renal threshold is 150ish on our Freestyle Lite meter. It tends to read lower in lower numbers. I stalked her every time she went to use the litterbox over the course of two weeks, and tested it with a urine strip. I compared the results of the urine strip to the previous 3-6 hours of BG readings.
At this point in our FD journey, I take her behavior as another indicator of her health. She's her best self in the 65-120 range (again on my meter) and most playful and kitten curious.
I also remind myself what others have said here over and over again for years. A cat is more than their numbers. I keep an eye on the 5 Ps.
Of course, it's important to get those annual checkups too. Semi-annual now that my Cleo is considering "senior" since she's 12 years old.
Not sure if I answered your question, JMHO from dancing the FD for almost 3 years.
