My late Domino, the best girl ever, was a diabetic in her later years too. I'm extremely squeamish and afraid of sharp objects , but giving the injections was easy and she actually liked to get them, along with the healthy treat and loads of attention that went along with a shot. I found the Feline Diabetes web site mentioned by makbike really helpful, and also monitored her BG levels. With a new high-protein diet and more exercise, Domino stopped needing insulin after less than a year.
