Thanks everyone for their replies.
I calmed down today, Zarley is acting fine (almost annoyed that I'm fussing so much over him), but his PMPS have freaked me out a bit (I freak at high numbers, I freak at low numbers). Tested for ketones. He just got a Lantus dose of .75. From mid-afternoon on, all he's pretty much had is fresh chicken (I felt bad for him and wanted to give him a special treat) so it's not like the food was carb-y. Tomorrow is another day.
They are calling for ANOTHER huge storm on Friday (we've had more snow this year than the past 5 years combined). Accumulations of up to 20" are expected (we got that much right before Christmas, too). Tomorrow before work and at lunch I'll have to do some more major stocking up. I'm fine with food food me but I want "more than enough" for the cats. I'm terrified I'll run out of testing strips (even though I just bought a back up for a second monitor) so I guess I'll get more of those, too.
