I just tested my cat's bg for the first time and he is on Prozinc 2x daily, 4 units each time. I give it at 9:30 am and PM. I took him off all dry food since his last curve at the vets which was on 2/4/19. His numbers were in the mid to high 300s each time at the vets so she put Stewie up to that many units. I was still giving him a 1/4 of a cup of dry food up until that day. He has been on only wet food since. I checked him at 3 pm today with my ReliOn meter and his numbers were 34 and 41 as I did it twice. I don't know what that means. I fed him after his bg test. I have been feeding him 6x a day since he is always hungry. I give him a quarter to a third can at a time. He's not acting any differently than normal and eating and drinking water ok. He is on Friskees pate and FF Pate. Should I be worried. I checked my husbands glucose to make sure the meter worked and his seemed to be right. I will call vet office tomorrow am.
