My third leg sensor, like the first, ripped out. I hadn't cut the hair on my leg first, and all the hair seems to want to stick to the sensor- static electricity, I guess- and it didn't stick well. After a few days it ripped out. I'll try another leg sensor another time. I went about a day without a sensor. I was feeling kind of discouraged about the usefulness of the sensors.
I went to get a free A1c done at a Minute Clinic (special runs til tomorrow, for diabetic adults only) and since it was a Bayer A1c now, I don't know how accurate it was, but it said 6.1%, which is the lowest A1c result I've ever gotten. The nurse practitioner got kind of defensive when I questioned the veracity of the test, but in a good way. She read to me from the study of the test, and I'm not sure I understood it. Either their math was inconsistant or I misunderstood, and I think I misunderstood. But she said it showed the A1c was only accurate to plus minus a percent- like a 6.1 could be a 5.1-7.1 - and that the venous blood draws were almost as inaccurate. I doubt it was right but in case it was, I went home and had my father put in another sensor. I'm very proud of him for putting in these last two. He is kind of cute and nervous doing anything with my diabetes but he did just fine.
I'm getting my A1c done by venous draw in another couple weeks so we'll see how closely it matches. I hope it matches. 6.1 would be ace.

I can't state for a fact that all mammals have pancreases because I haven't got a source for that; but I believe it's true. Birds have pancreases too.
Dogs are even more likely than humans to get diabetes; in addition to an autoimmune diabetes that's like type 1, old dogs tend to get pancreatitis, which is an incredibly painful disease that can cause diabetes. Cats also tend to get insulin resistant as they get older, and also sometimes get pancreatitis.
Cats and dogs have about the same normal range for blood sugar that humans do.

Pigs, on the other hand, have a normal blood sugar range of 20-80. That's right, folks; a pig with a blood sugar of 25 is happy as a pig in a sty.
I learned this fact while reading about development of an artificial pancreas being tried in a pig where the authors were wondering about the issue of maintaining pig blood sugar in human range even though that's not where pig blood sugar is supposed to be.
