Ok, now I'm catching up.
This is your condo/thread from yesterday:
https://felinediabetes.com/FDMB/threads/09-26-sulls-amps-326.235969/#post-2645293
When I clicked on your link it took me back to 9/24 and I didn't comment that day...thought for a minute there I was losing it!!
Anyway...vets often prescribe 2 units to start - it's just standard issue - what's good for every cat, is good enough for your cat - and that's what they go with. Even Luci who was about 8 pounds when we started - the vet said, start with 2 units and get a fructosamine test next week...right....
Needless to say that was a disaster as well...but in the meantime, you've got a lot of help, support and guidance here already - just like I got...
I think you may want to wait and see how the day goes as far as the numbers - then decide on a dose tonight.
What kind of food has Sulls been eating (this may have been discussed previously, but I can't recall what was said, if anything). I see from your signature that he's eating FF pate now...has that always been the case?
