Hello there! Welcome to the LB&L group. I just have to share that we too had a very difficult time getting started with the testing.
Luci was diagnosed by our vet who said she was so difficult that it would be best to euthanize her - that she wouldn't come to us for shots and most certainly would not allow any testing. What a dire guy he was!
So I started searching the web and found this wonderful group of people who encouraged me to try several things. At first DH had to hold on to Luci to keep her from escaping and fighting with us but after a while she sorta got used to the idea. I found it especially helpful to call to her and put her on the testing towel in the same place every day - several times a day - without doing any poking at all. I'd just pick her up, set her on the towel, pet her a bit and talk to her and then she got a treat! No poking involved...we did that over and over and over...and every now and then - well she did get a poke...but soon she started to come more willingly and the next thing I knew she was SITTING on the towel WAITING FOR ME! I was stunned! I thought it was so funny I took a picture of her laying there like a queen - waiting for her servant to come and provide the necessary routine in order for her to get that treat.
I use a warm rice filled sock to stroke her head, neck and shoulders a bit - she seems to love that warm massage - and then I place it under her ear, and do the poke while I support her ear with it.
It does take time, but she doesn't object at all now...in fact some times she purrs through the whole process..
So, be patient with your Yuki...try some of these tricks...and please get those pre-shot tests - they are so critical. You'd never want to give insulin should that number be too low.
Please post again tomorrow! We'll be looking for you to see how you and Yuki are doing. Nice job with setting up your first post in the LB&L forum!
