You've come to the right place. Look at the forums devoted strictly to different kinds of insulin, you won't find that anywhere else. Let your introduction sit here until tomorrow morning and then post in Feline Health with your cat's name, age, other medical conditions, type of insulin you're using and the dosage you're starting at. You'll meet a lot of interesting and caring people, some of whom know more than the techs at my vets office and some who know more than vets. Remember that no question is too stupid and being emotional is part of the package. Noah is my second diabetic cat and I've seen all the other "informative" sites, this is the place to be. Welcome.
