@Sue and Oliver (GA) @Rachel @Robin&BB @BJM @scoobydoox Switched to ProZinc today (8 am UK time), 3 1/2 units and doing a curve. Some quick info (this is also in my previous thread http://www.felinediabetes.com/FDMB/threads/switch-from-caninsulin-to-prozinc.159005/#post-1695009 and in the detail bit in my profile): He is still eating the Hills dry M/D and is still having a pancreatitis flare-up, plus he's on antibiotics for his upper respiratory infection. I understand the antibiotic itself raises the numbers? The latest antibiotic is Marbocyl. We tried Synulox but the infection came back, then another course of Betamox (?), and it didn't solve it. He has been on Marbocyl for the last 5 days and I am going back to the vet's today for more. Any advice on this would be much appreciated, too (e.g. ideas about a better antibiotic or ideas on what else to do to help him). **UPDATE**: Vet recommended holding off on more antibiotics for today and tomorrow, to see how he does.
