Default U100 syringes

I started my fur baby on Novolin N and so far it is going well. My problem is with the U100 syringes. She was on 8 units of Vetsulin so I started her out with 6 units of Novolin N. I would like to increase her to 6.25 units but eyeballing it on the U100 syringe is next to impossible. After extensive searching, it appears I can not find a smaller U100 syringe than 30 units. I am tempted to use U40 syringes with the Novolin N (a U100 insulin) unless someone here explains to me why I can't. According to my math, since Novolin N is 2.5 times stronger than a U40 insulin, then 6.25 units of U100 insulin would be 2.5 units on the U40 syringe. This would be significantly easier to read on the U40 syringe. Is my math right? Do you agree? Or am I totally off in my reasoning or approach? Is this not a viable solution? Image:

I'm thinking of doing the same thing and looking at it the same way.

I would not use the U40 syringes with nph insulin

If you have the half unit markings on the 30 unit syringes its quite easy to get the quarter mark. its just midway between the half and full unit mark . I have to wear glasses to see those marks . There are members that said they could attain a 1/8 marking
Jesse-26 lbs - 15.5 years old - 10 years diabetic - one meal a day homemade and a vitabone snack - 3 shots of Novolin a day sometimes Novolog or r as a correction to higher sugar but that is rare. total insulin for a 24 hour period is between 8 and 10 units of NPH insulin depending on her fasting number

When you draw the insulin to the 6 mark, just have a little daylight showing below the line. I don't think being exact is necessary, as such slight variations probably won't have a significant impact.

It's generally not like a machine, where the body uses the insulin exactly the same each day.
Vets usually increase or decrease by 0.5 units at a time. I believe that much is probably necessary for a body to experience an adjustment.
Riley, 8 yr. old maltipoo, 25 lbs., diagnosed Feb 2017, taking thyroid meds, had pancreatitis and DKA mid March, eating Wellness Senior formula can food. NPH dosage now at 9.0 units Humulin N. Adding either pumpkin, spinach, blueberries, yams, or green beans to his food. Also omega-3 oil.
