Hi, and (((hugs))) to you. We all know how hard it is to start caring for a diabetic cat. It's such a steep learning curve.
This (see quote above) really jumped out at me from your post... I'm really sorry but if you have a diabetic cat in your household you really should NOT have dry food available for him to eat. This could push your cat's BG levels much higher than they'd otherwise be and could totally negate the valiant efforts you are making to try to regulate him.
I do understand how hard it is to change a feeding routine. I've been there. I have a multi-cat household (5 cats at present), one of whom was diagnosed with diabetes five and a half years ago. I was feeding all the cats Science Diet because I thought it was good for them, and because it's so clean to use, and no waste! I thought it was fantastic! But I had to switch all the cats to the food that was best for my diabetic cat - low carb canned food. It wasn't easy. They protested. A lot. And I felt really mean not giving them what they wanted. But I kept some dry food on hand and sneaked the non-diabetics a few pieces now and then while I weaned them off the stuff. I still have some available - but I use it only for emergencies when my diabetic cat's BG is dropping too low. I still give the cats treats, but only those that are made out of pure chicken (no carb).
NOTE!: Taking the dry food away might make a significant difference to a diabetic cat's BG levels. So, for cats on insulin, it's vitally important that you monitor the BG levels carefully during the switchover to (only) canned low carb. Don't remove all the dry food at once. Phase it out gently for safety's sake. But be firm; once it's gone, it's gone for good...
Re your meter readings (on the two different meters) being SO different, well, yes that is really odd. Did you do the two meter readings one straight after the other? If so, then something is clearly amiss. Does the meter you bought have test solution with it? If so you can use it on one of your test strips to see whether it is working correctly.
Re your insulin dosage: I have no experience of the type of insulin that you are using, but please be guided by others on this site who do have that experience. The consensus is that the dosage is way too high to start out with. And his insulin needs could decrease further if/when you remove the dry food. Too much insulin could cause your cat to hypo and you really don't want to be dealing with that at this stage of the game. You have quite enough to deal with already! There's a saying often quoted on this site regarding cat's BG levels; "Better high for a day than low for a minute." Memorize it. I've lost count of the times that bearing that quote in mind has prevented me from making bad choices...
You've only just begun this journey with your newly diagnosed diabetic cat. Slow down. It's a marathon, not a sprint. And it does get easier. I promise.
All good wishes to you,
Elizabeth
