Hello everybody! I'll try to make this as brief as possible. Our 13 year old male cat "Picky" was diagnosed in February after a set of very stressful events at our home. Prior to that, he was already diagnosed with a slight arrhythmia that was controlled and medicated properly. We started to administrate him 1 unit twice a day of Caninsulin and a pill of Metformine twice a day, we also changed his meal to Royal Cannin's diabetic and got ourselves a BG meter to test him at home. His tests were never good, except for about a couple of times, they were always over the 500's. We started to gradually increase his insulin intake up to 8 units a day which is what we are giving him now and still his tests are over the 500 range. In the middle of all this odyssey we got him blood tested and noticed his kidneys were also failing so we started an intensive treatment that gave good results, but he is still under control. The vet changed his food again to half renal control, half diabetic (all dry kibble) which is the only "good" type of food I can get where I live. I also got him checked by a diabetes specialist last week and he wants to keep raising his insulin at least for a couple more units and see how it responds. I'm aware this is a hard case but I still wanted to have other views and insights. Thank you all in advance.
