Unfortunately Bud isn't OTJ, you must have seen it in someone elses chart. Bud isn't even regulated yet, but I am switching to Levemir Friday, so I am really hoping that helps his numbers.
That is really awesome that you found a pharmacy to sell you one pen for $25! As far as the testing goes, what helped me the most in the beginning was to use a bigger gauge lancet, like 26 I think. They are made for alternate site testing. Now that I have the hang of testing, I switched to a 30 gauge lancet. Warming the ear with a rice sock helps tremendously too, and I still do that. Also he gets low carb treats after testing like freeze dried chicken or sometimes I'll bake plain chicken and shred it for him. Is your cat squirmy or is he tolerating it pretty well? I just wrap Bud's front paws up in a blanket as he does like to get feisty and try and get away sometimes. Checking every 2 hours is a perfect plan, but kitty might need some time to settle into that 2 unit dose before you will really know how it will effect his numbers since Lantus builds up a depot.
