Hi, My cat Ron has been testing around 300s regulary, he is taking 3.5 prozinc twice a day. He's on the diabetic dry food and ff classic. The doctor told me to stop testing him every day so we got pretty lax about it. It's been about a week and a half since I last tested him and he was 250 then. Today I tested him and he was the highest he's ever been- 425. I am really nervous, but the vet said to go by his symptoms more than anything and he's acting fine. He isn't excessively drinking, he isn't peeing a ton, he doesn't seem ravenous or lethargic. He's affectionate and seems fine.It is possible that he ate some leftover food on the floor that I didn't notice when I wasn't looking so that could be why he tested high. Any advice? Thanks so much!
