If you got that this morning, test him again. Give him 1-2 teaspoons of high carb food. Although you don't see any symptoms, he could be dangerously low.
With test numbers like that, I would act as if the cat was nearing a hypo situation and start feeding. I'd rather be wrong about that and elevate the glucose unnecessarily, than assume everything was OK because I tested OK and do nothing.

How to Handle a Hypo
Whenever you get a wonky test, retest. Make sure your hands are clean and dry. Make sure the test strips haven't expired or been sitting out too long, amd have been stored in a dry place (moisture deteriorates them).
The FDA allows meters to read within 20% of what a lab would get. So take your test numbers and add and subtract 20% (or multiply the number by 0.8 and 1.2 - you'll get the same thing.) If h\the ranges for 2 tests, taken at the same time, on the same blood drop overlap, they may be considered the same.
0.8 * 32 = 25.6
1.2 * 32 = 38.4
0.8 * 34 = 27.2
1.2 * 34 = 40.8
The 38.4 is higher than the 27.2, so the ranges overlap and the values may be considered the same.
Also, human glucometers are normed for human blood, so the results will be somewhat different for the cat.
