I'm fairly new to the board, and I have learned so much since our kitty was diagnosed (on 9/11/17). Our vet prescribed PZI to be administered in 2u increments, twice daily. We switched his food immediately (he was eating dry food, and I feel terrible that we fed him that!) to FF classic pate, and we've learned through the board about "no-shoot" numbers, etc. I have stepped back his dosage to 1u and sometimes I'll skip the shot altogether. We test every morning and evening to get a pre-shot number, and when we're home we try to get a few tests during the day, too. We don't have a TON of data yet, but I was hoping someone who is a bit more knowledgeable and experienced can look at his spreadsheet and tell me what you think. For the record, his glucose levels haven't been very high. Part of that was him not eating as much as he adjusted to the new diet. His levels the day he was diagnosed were north of 500. His eating habits are getting back to normal, but we no longer free-feed. He eats (close to) a can of FF pate in the morning and another at night. I greatly appreciate your feedback! Thank you! This board has made this change in our lives so much easier. And our cat, John Denver, is finally back to his old self!
