I did my glucose curves for my two diabetic kitties on sunday. I haven't gotten a chance to do a spreadsheet yet but one of the cats, Frank, had numbers that read like 320, 140, 138, 329. He is 9 yrs old and around 16 pounds(large cat but also overweight). He has been on Prozinc for 3 months and the old vet we were seeing jumped him from 1 to 3 units only 3 weeks in. After reading some things and the help from this site I knew that wasn't the greatest idea. I have a new vet that has been working with me but when I gave her the numbers she said she didn't like the way his BG was still going into the 300s and wanted me to bump him up to 4 units. I don't want to not listen to this vet either but she had previously told me she typically only increases in half doses so I'm concerned again about another drastic change. Is 4 units 2x a day a typical dose of Prozinc or does that seem excessive?
