See if you can cadge some little bottles of saline, like you get the insulin in. Maybe the bio dept has some if it the college has some sort of nursing or nurse-tech type program. Or maybe your clinic will have some. I got them for mixing with powdered fertility drugs. And an empty one that just has air if possible, otherwise you'll need to pitch half the stuff. Anyway, then you can then mix your insulin 1:3 with saline and be able to happily measure what looks like 2 units on the syringe and is really 1/2 unit. It made my life with a barely-diabetic cat much happier. You'll need some much larger syringes for doing the transfer. Cadge these from the vet as well.
