I have a newly diagnosed diabetic we are trying to regulate on ProZinc. He had DKA but did not stop eating or seem to feel bad like most DKAs. He was hospitalized for several days. He is the littermate of ANOTHER 14-year-old-diabetic who uses ProZinc. So I have my hands full! The newly diagnosed cat is wearing a FreeStyle Libre sensor, so I have a lot of info about trends. (Until the cursed thing stops working, which is another subject.) He is consistently dropping drastically by four hours. This morning at shot time he was at 360. Three hours later he was at 150, four hours later at 80. I fed him and he is going back up. He does not display any symptoms of a hypo. This is a recurring pattern, both day and night. Typically it takes an hour or more after feeding for him to get back up to around 150. Without being fed, I have seen him drop to 100 and then head back up (that was nice!), but I have also seen him drop into the 60s (at which point of course I was feeding and reaching for the syrup). His vet, which is a very highly regarded clinic, is not concerned. But I am, and I have learned to have the courage of my own convictions! I have already lowered his dose from the 2 units they recommended (that only lasted one day!) to only 1, and I am still seeing this. I would like to keep him on ProZinc if possible, so I don't have to deal with two diabetic cats using two different insulins. Any thoughts? SHOULD the regular drop to 80s scare me? I could reduce the dose to .5, I suppose, but at shot time he is consistently in the 300-400 range. I can't stay home forever to feed him at four hours post. Thanks for any thoughts.
