Hello, so my cat Jax gets 3.5 units of ProZinc and his numbers usually read high 300s or 400s pre-shot. I noticed that the last couple days his numbers were lower pre-shot (yay). So my question is: when his numbers read lower how much insulin should he get? Is there a rule of thumb to go by, like over 400 or high 300s, he gets the full dose, 300-200 half his dose? I know my vet says 3.5 units, but that's when his numbers are high and I know you guys base your dosage on the glucose number which makes way more sense. Please help me understand. Thanks
