Welcome to the boards.
Could you give us bit more info on you and your cat?
What's your cat's name and age?
What food is he currently eating?
What symptoms did he have, if any?
Do you have any blood glucose numbers and did your vet dx on just 1 test or on a fructosamine test?
What type of insulin has been prescribed, ie. the name. The prefered ones are lantus, levemir and prozinc for cats.
Have you given insulin yet?
Sorry for the questions but it helps get a full picture of where you're at.
There is a lot of info on the site, start here:

Read as much as you can, particularly the stickies at the top of the forum.
And ask as many questions as you can - no question is too silly for us!!
