I test Skooter from his ear....
A lot of people on here will suggest doing it slowly....making sure you test your kitty in the same area each time....bring him over to the area, and snuggle with him, rub his ears and have him associate that with a positive feedback....I have not had to use a rice sock yet, but I will be as I want to try to get his left ear to bleed well for me.... so fill a toddler sock with dry rice and put it in the microwave for 10-15 seconds and then place it by his ear, that will help warm things up and make the blood easier to get....
Right now Skooter can't have treats, so after we test (successful or not) he gets love of love and attention.....
I try to remain as calm as I can and Skooter is getting much better at just sitting there and tolerating it....he sometimes squirms, but I notice that is when I am a bit stressed myself.
I do it solo as it is just me and Skoots....but perhaps it might help if one of you calms and soothes him while the other does the quick prick....I have also picked up the trick of using some neosporain with pain medication, which apparently helps the blood bead up better.....plus it gives a little pain relief and helps heal...
Personally, the videos I googled did not help me that much, I went into my vet's office and they showed me how to do it and then took some of the advice I have listed above from all the fine folks here and made it work for us...
I know that some of the people who have been here awhile will have links to some videos and information as well, but thought I would throw my two cents in there
I swore up and down that I would never home test because it scared me too much, now, if you look at Skooter's spreadsheet I am testing all the time, to the point where I have had to promise to not test as much and give his ear a break
Good luck in your quest to ear test!
