It's already "shared" in you "Signature" (the stuff you see below our comments) You should add some other information to yours when you have a chance like:

Your name/Cat's name, age, sex, date of diagnosis, type of insulin, type of meter, type of food, any other health issues or meds? and of course, your spreadsheet link which is already there!

1.5 dropped him a little lower than we like on Caninsulin so I'd try the 1U dose if he's above 10
