Hey, Ramen is good! Seriously Lyss, the important thing is the testing. I would not say that because the pet meter is more expensive that it's better quality. People with diabetes use the human monitors..and many many use the ReliOn Prime, and it's just as critical to know human BG as it is cat BG. We started out with the AlphaTrak2 as vet suggested, but just couldn't keep up with the cost. So, it was down to go without testing consistently, or use a human meter with affordable strips.
Here is some info from my "files":
Meters: you can use a meter calibrated for humans-- the numbers won't match pet meters your vet might use, but all you really need to know is what is "too low" (50 and below on a human meter), what is "normal" (approx 50-120), and then your own cat's relative numbers (going up? going down?). The big expense on supplies will be the strips, so shop around before choosing a meter to figure out what works for you. Many in the US use one of the Walmart ReliOn meters because strips are pretty cheap and Walmarts are open all the time for emergency buys, but you can also often get good deals on strips for other meters on Amazon or eBay.
Human meters do read lower than pet meters, and BG range in the dosing protocols are adjusted accordingly. For example, a normal range on a human meter is 50-120, while on a pet meter it is 68-150. You cannot compare numbers from a human to a pet meter because you're using a different point of reference for them. It's more important that a meter be consistent, (we are generally looking for trends in data to adjust the dose, not single, exact numbers). There is also a +/- 20% variable allowed in any glucose meter, including pet meters.
You can’t translate numbers from a human meter to what they would be on a pet meter. Then are no studies which provide a correlation between the two. However, it’s equally important to note that 50 on a human meter does not equal 68 on a pet meter. Those are the numbers which have been determined to provide a safety net.
