I ha started a thread and was directed to post here where the Pro Zinc experts would be. Linus was diagnosed 3 years ago and used Novolin N for the entire time, we had good success for the first 2 years, since then it has been a roller coaster ride. The vet finally switched him to ProZinc, but trying to get the dosage so he does not drop too low or get too high is difficult. We are cat people, we have 7, Linus is 14, his mother Abbey is 17, Frank Sinatra 11, Blondie 11, Molly 11, Cleopatra 11, Garfield 6, he was found in the back of a delivery truck at 3 weeks old, we got him through pneumonia, and he had mega colon so his colon has been removed. Our kids are grown and have families of their own, our cats are our family. We lived in the country for years, and plan to do so again soon, when we did, people were always dropping cats off , we would take them in , bring them to the vet to get fixed and healthy, inoculations, vitamins etc and adopt them out for free. We are not strangers to medical needs and hands on care, but this diabetes has thrown us for a loop. Linus has lost so much weight he is skin and bones, I fear for him right now and need help to get him healthy and managed. I will be providing a spread sheet when someone helps me make one. We started the ProZinc on Thursday Morning July 14th, this is the data I have compiled thus far... A couple questions first please, what is the idea number for his BS I am shooting for so he can gain some weight? The vet gave us some wet and dry W/D Digestive/weight management, would this not make him lose more weight? He is not a big eater per meal, but grazes every couple hours per day. I do have open feeding with 7 cats with dry food, I have Cat Naturals and Kitten Chow as those were the higher protein foods I could find in our price range. Linus eats mostly wet food, Fancy feast chicken, turkey and giblets, chicken and liver, and some Friskies turkey and giblets. He will eat a bit of dry but not more than a couple times per day, and approximately 5 to 6 pieces per time. Here is the data: Blood sugar morning 376, gave him 1 UN Prozinc; 1 hr after shot BS 313 2 hrs 343 3 hrs 285 4 hrs 297 6 hrs 252 Keep in mind he is a grazer so this is not going to be easy. Evening Blood sugar 381, gave him 1.5 as we thought his daily numbers were a bit high 1 hr after shot 329 3 hrs 215 6 hrs 190 Day 2: BS 349, we gave him 1.5 UN, still trying to get him between the 120-170 that he should be at, is this the right range, will he gain weight as he needs to badly? 2 hrs after shot 247 4 hrs 136 6 hrs 98, we gave some wet food and few drops of Karo as we thought below 100 was not good. 15 minute check after the wet food with the Karo BS is 113 7 hrs 200 Evening BS 308, we gave him 3/4 of 1 UN got up 4 hrs later to check him and BS was 190 Day 3: BS was 363, we gave him 1 UN as we feared he would drop too low like the day before 3 hrs after shot 150BS 4 hrs 98, gave a few drops of Karo in wet food again as he was below 100. 5 hrs 116 6 hrs 120 Evening: BS was 381, we gave 3/4 of 1 U 3 hrs after shot 330 5 1/2 hrs 317 Today thus far: BS 329, we gave him 1/2 U ( .5) 2 hrs after shot 312 4 hrs 300 6 hrs 347 8 1/2 hrs 382 I use a human blood sugar meter Relion Confirm, we had the same tester for 3 years so we just went and bought another to make sure we were getting the correct readings, they us .3 blood, and don't seem to bother Linus too much. Will this give the correct readings for a cat? We love this meter, happy we bought the same one. With the Novolin N , he had been on it so long we had a cheat sheet we used to know within 10 BS points what dose to give him, with this new insulin I am worried we will not get him regulated, he has lost SO much weight, I have to get some weight on him, any suggestions and help will be more than appreciated. Thank you Anxiously awaiting a reply in Minnesota.
