Yeah, the last time we were at 2.5U it seems like results became apparent right away, with 5 very good days before be went too low. Maybe it hasn't been long enough to kick in, but I'm not seeing the same effect this time around. In fact, his PM numbers today are confusingly elevated.
As for his morning behavior, I think he is just being a pill because he can get away with it. I started other human off with testing on his rear pads because they're an easy enough target to start getting comfortable with the process before graduating to ear testing. So he'll scoot around, or kick with his other foot and smear a hard-earned bead of blood, get up and run away, or get aggravated by his civvies when they come sniffing around for the treats that are meant for him. Eventually, after 30 minutes or so of this, other human is exhausted and frustrated and admits defeat. So the goal for today is to isolate him from those distractions as test time approaches by putting him in a separate room to see if it calms him down from being so feisty.
