One thing you could do, if you really want to know cat numbers, is buy a pet meter and use it occasionally to see the number. What you can’t do with it, however, is try to correlate those readings with any you get on a human meter even if same blood drop. As Wendy said, there is no conversion factor. Each meter works with an electrochemical reaction that takes place in the strip and transmits the electric reading to the meter, where algorithms based *on species specific criteria that is quite different between cat and man* translates it to a displayed number.
It is not a mini lab in your pocket but an approximation of what a lab would say, again based on math that applies only to a single species. Because of variation in accuracy and precision, on circumstances such as temperature, anemia, etc and the species difference in how glucose is stored it’s impossible to translate one to the other. In general in a non-anemic cat the human meter reading using cat blood will give a falsely lower number. But not always and how much lower has huge variation.
Anyone who says they have figured out a conversion factor doesn’t understand how these meters work.
