    Hello, I introduced myself in a panic the other day.... My Colby has been struggling lately with eating his wet food and getting high BG numbers. And no, I still haven't done my spreadsheet :) I'm feeling better now, and have a plan of action which I need to discuss with my vet.

    I would like to talk to my vet tomorrow about trying a different insulin. We just started Vetsulin Friday after being on Novolin N since mid 2013. After doing some reading, I would like to try a different insulin ... I think BCP-PZI. I'm just having trouble understanding the difference between Prozinc and PZI. So, Prozinc is human origin? and PZI is bovine? And there was a shortage of bovine pancreas a while back, but apparently there is a company, BCP, that compounds the PZI? But then I read that some people advise against compounded PZI. What do people here use if they are using compounded? Sorry, I just want to make sure I understand all this before I talk to my vet.

    Thank you, and I must say, I am very impressed by all the knowledgeable people on here and their willingness to help!

    They are 2 different products.
    I use ProZinc; it was designed for cats.
    Note that the BCP PZI can vary some batch to batch.

    Some cats do better with the BCP insulin since bovine insulin matches cat's insulin better than human insulin.
  4. Prozinc is thought to have a slightly longer duration (10-14 hours) than Compounded PZI (8-12 hours).
    BCP costs about half as much.
    My cat was on Compounded PZI for 10 weeks and went into remission.

    Thank you.... I stayed up way too late last night reading about the different insulins. I understand the differences now, but I keep going back and forth on what to try next! I've been scouring the board, reading about other people's experiences and taking notes. I have an appt tomorrow afternoon with the vet and hopefully he and I can come to a decision. :)
