My kitty was diagnosed and put on Prozinc right before Christmas. I have been working with someone on another feline diabetes page. We have not been able to regulate kitty yet. They think that the prozinc could be lasting more than 12 hours. Now are suggesting possibly switching to Lantus. I would like someone to take a look at the spreadsheet and give me their observations and advice. We all want kitty to get better, I just want to make sure I am making the right decisions for him. Thanks!
