My fat cat was diagnosed June 20, 2018 and was on ProZinc. On Aug. 25, I changed his diet to all canned food - Fancy Feast chicken feast pate. He hasn't had BG above 10.5, or 190, since Sept. 9, 2018. The last time he had insulin was Sept. 8. I just tested him an hour after he ate, and he was at 5. So two weeks after going on all wet food, he no longer needed insulin. I want to thank people on this forum for helping me when I started doing home testing. You helped calm me down and answer my questions. I am so pleased my boy doesn't need insulin anymore. He is playing more -- he even caught a couple of mice -- one outside and one inside our travel trailer. His coat is shiny and soft, he pees WAY less, he is putting weight on and sleeps less. I hope he continues this way. I will never again feed him dry food. I wish all of you the best, and thanks again.
