My Levon is a difficult kitty! He has been in remission before, for over a year. Now, at 1 unit twice a day he goes too high. At 1.5 units twice a day he goes too low (56 last week on AlphaTrak.) Because of his history, our vet is reluctant to increase his dose, since he seems to be so sensitive to insulin. Not much wiggle room. I would try 1.25 units, but those markings on the syringe are just too small to read, and two different people give him his shots. I've read the recommendations here about using syringes with 1/2 unit markings, but I can't find any. Neither Walgreens nor Costco carries them. Where do you guys buy yours? I just want it all to be "just right."
