My Fabby actually terrified grown adults in her heyday. She would be the first one out to greet guests, and meow for them to pay her attention. She allowed 2 pets then she'd smack. She has no fangs, and I keep her nails trimmed. So she's harmless, but grown people would change seats if she was staring at them. Lol. These were regular visitors...
She also would wait until I was looking at her then she would knock off my stuff from my nightstand so I'd have to get out of bed. My personal grumpy cat.
So when we started testing I would sit in the same spot, give her pets in my lap, rub her ears to warm them, lay out my supplies including her treat pouch. Then poke her ear. Sometimes she's grouchy about it. Flicks the blood off before I can get it I the strip, growl/meow, turn her ear... She's trying to see what I'll let her get away with, just like she enjoyed making visitors get out of their seats. So I just grab the other ear and poke. Generally, she didn't make me poke twice, but sometimes she gets in that mood.
(I once had to poke 3 times because she flicked off the blood.) But all is forgiven when she gets her treat after the number comes up. Generally if she sees the treat she won't act up. (Learned that part slowly, lol.)
Another person has said if you can prick and get the blood on your thumb nail quickly you can use that blood to test instead of trying to bring the strip to they're ear.
Good luck getting into your routine!
