I'm lost. Can't figure out WHERE to type the introduction. Maybe I did this right? I hope. This forum is hard to figure out taking time where research can be done. I'll try a bit more. I'm sure it is because I'm not someone under 30 yrs.
Welcome.
Yes, treating diabetes can be intimidating at first but it does get easier.
Good insulins are the human Lantus and Levemir and the pet insulins ProZinc and BCP PZI. For those two human insulin it is best to get the 5 pack of 3 ml disposable pens via a 10 ml vial. Although per ml the vial is less expensive most cats will not use up a 10 ml vial before the insulin goes bad/becomes ineffective. The human insulin N/NPH is sometimes prescribed but only lasts 8-10 hours. Same for the pet insulin Vetsulin/Caninisulin.
Most of us here test or cats blood glucose at home using a human meter. We test before each shot and periodically between shots. We record our reading and other info in a spreadsheet. See: http://www.felinediabetes.com/FDMB/threads/fdmb-spreadsheet-instructions.130337/
