I just started giving my cat Bryant ProZink 1u yesterday. He’s had 3 doses so far. I’m checking his BG with a AlphaTrak meter and the number has been rising from 420 to 683 a short time ago(after his shot 2+ hours ago!) Should I be worried? I started him on vet prescribed food, Hills and Purina but all the wisdom seems to point to going with Friskies pate and FF(which I’ve bought and researched the lowest carb ratings for the types I bought. I just wondering if the script food is spiking his number. Can I switch up to the cheaper food?
