My best tip, the thing that worked for me, was to pull the cap off of the lancet pen and just use it with the lancet exposed. That allows me to see where I am pointing (I can be more precise). If you want to try this: cock the lancet pen; with the cap removed and the lancet exposed, hold the pen a millimeter or two away from the ear (don't touch the ear with the lancet tip); then hit the release button.
PS: To everyone who is having difficulty, this DOES get easier with time. See my spreadsheet below. I was the absolute WORST at getting readings initially. In fact, I may hold the FDMB record for "worst tester." At first, I had to chase my cat Ninja around the house, tried wrapping her in a towel and a blanket (she escaped); and when that no longer worked, I cried, gave up, tried again, cried some more, gave up again, thought about getting drunk (but didn't), and kept trying. I got ZERO readings the first week and maybe 1 the following week.
Associating the testing attempts with a treat, OVER TIME, was what finally worked. It didn't work the first day or even the first week for me -- my cat may be slow -- but over time, this association has worked and she now purrs during testing. Also, what worked for me was not traumatizing her by poking 10 times in one sitting. I decided that after a couple of pokes (successful or not) I would let her go, treat her, and try again later. That way, she would not be so fearful next time. Another point is that, over time, the cat's ears will start bleeding more freely (they grow additional capillaries I am told) if you continue to stick them daily -- so that within a few weeks, you will get blood on the same one or two pokes, where now you may be getting nothing.
So, keep trying -- but don't be too hard on yourself (or your cat) if it takes a little while to master this. FYI: Just because your meter came with 31 gauge lancets does not mean that's what you have to continue using in your lancet pens. Most pens accept other size lancets. I bought a box of 28 gauge and am using those in the pen that came with my Relion Micro.
