My cat Bryant, unknown age, maybe 15-18, diagnosed Dec 26, prescribed PZI insulin, 1u, his first 2 doses yesterday and last night. Using AlphaTrak meter. His number yesterday was 420. I didn't test last night but will test again today. I’m pretty overwhelmed as I read so much conflicting info and realize there is a lot of support but don’t understand the disconnect and difference from the info I get from my Vet! I have even gone so far to try and get a 2nd vet opinion.
