I have a Relion Micro, and I freak out too! I bought 2 boxes (200 count total) alcohol wipes and I found at first I might not need them, but then when I started I found.... I NEED THEM. I wash my hands before testing but I have to pet, love, scritch, groom soooo much... my hands start to feel abit ichy even though Fena had been bathed and she's clean. So I use the wipe on my hands once I have her calm and relaxed - or if it doesn't take much for her, I'll use one on my supplies. Outside of bottles, kit bag, etc.
So long as I don't waft the smell by her face, she doesn't care - she's starting to learn, "Oh okay my Mom's nervous and this is the smell, eh, whatever" - I swear that's the look on her face. I do 2 pokes because I'm still really new at this and.... Fena doesn't care. Literally. She's more interested in my hands or what I'm holding, than the "sticks" - which has its own problems, believe me! Same thing for her insulin shot - bright eyes, happy face/ears/whiskers, she just.. goes with it, but I'm messing with her, so she's happy.
Course I have problems... that happy can mean paws, etc. as she thinks I'm playing or it's a game, etc. for testing especially - not shot, surprisingly.
One weird trick I've learned? Does your cat like ear cleaning wipes? Fena LOVES the hell out of them - if I use one of those, her eyes close, she drifts off in this weird daze.. and I can test, no problem! Maybe buy ear cleaning wipes? Anything I do with her ears, she loves - kisses, lipping, nibbling, finger rubbing - if I do it long enough I can put her to sleep, I don't know why. Mao is getting to that point to and I'm SOOOO happy since he's the "sensitive" one, just in case.
Speaking of which I need to update my damn spreadsheet, grrrrr - I forget that! I have my results in my notebook, but forget to update online.
PS - point of note! For Fena I've noticed, if I finger the edge of her ear enough I can FEEL the vein - most say to warm the ear and poke but I think they leave off the FEEL part sometimes. If she won't hold still for my small flashlight, I "feel" her vein - where I feel her heart beat after a lot of rubbing, I go to the edge and less than 1/2 inch of where I felt the pulse - usually above where I've been rubbing. Human nurses say the same - watch what fingers you use to test pulse/blood/vein. It's true!
