I think you are correct that you'd measure U100 insulin to the .6 mark in a U40 syringe to give you 1.5 units of U100 insulin. But I am so used to using this chart the other way round, that I would really appreciate you hearing from somebody else first before administering insulin! Sorry if that sounds daft, just want your kitty to be safe (my brain is a bit foggy today...)...
