About a month ago my cat was diagnosed with diabetes. Glucose readings were in the 500’s. After 5 glucose curves spread over two weeks we were set to 2 units of prozinc twice a day. About 2 weeks later I started home testing. First day I got 157 pre- shot and it continuously went up all day peaking around 430. Next day started at 168 and 3 hours later 38. He was fine and bounced right back after some food and reached 380 by that night. 3rd day after having those crazy results I took him to the vet for them to do another curve. Once again continuously went up all day to around 430. Today we started with 207 pre-shot and I decided to lower his dose to 1.5 but we still hit a low too low 47. He’s comfortable now around 150. I’m planning to lower again tonight to just 1. Am I right thinking he’s getting too much insulin? He’s being treated at a Japanese vet and they advise free feeding which I ignore, and have gradually moved him to a strict 2 meal per day wet food diet with a few pieces of dry diabetic as treats after tests. I’m hoping it’s the change in diet that is helping me to lower his dose so soon? It seems 2 units is putting him in this roller coaster one day too low one day too high too low too high. I don’t think we are near remission since approx 1/8 cup of diabetic dry brought him from 38 to 280 in less than 2 hours I think he definitely still needs it just maybe not so much? Also, this vet as I said wants me to free feed, but another told me absolutely not to. Free feeding isn’t really an option because he’ll just eat it all and I don’t know how long I can guarantee to feed other meals at the same time every day. I’m getting a lot of negative feedback on choosing to go to twice a day and looking for suggestions how to possibly space out food without causing even more crazy results. We obviously still haven’t found the right balance of anything and I worry making these changes again will set us back.
