I am on my third diabetic cat. One died at 12 because I was out of town and he was not given proper dosage and he spiraled. Second lived to be 17. My latest is 6 and just diagnosed a month ago. In my experience feeding them lower carb food is affordable, high protein for dry, pates for canned. I bought the glucose Rx food from the vet on day of diagnosis just because I didn’t want to argue with her. That was $80 for an 8 lb bag, I just cannot afford that plus I have another cat at home and can’t separate their food. I have read if you can afford to give them a 100% diet you can wean them off insulin. Take that with a grain of salt. The $20 Brandzig needles on Amazon are good and “pain free”. We tried the cheaper ones and they seemed more painful to the cat. The vet on my recently diagnosed cat wanted me on the “better” insulin that is twice as much. I’m starting with the “proven” Vetsulin for now. You’ll do great, they all act like normal when properly medicated. 😻
