Hi all, my cat George was diagnosed with diabetes in October last year. At time of diagnosis, he had pancreatitis, UTI and a weird sound when he was eating that was confirmed to be due the affects on his kidneys. After starting him on PZI and up until January, all results were improving although all still relatively high and so not in remission. His behaviour was also becoming more normal for him. However, since January, his results have gone right back up to where he was at diagnosis and all his symptoms have worsened again. The vet has said it could be how we are administering the insulin, the insulin itself or insulin resistance. I am 99% certain we are administering it correctly however we are going to do a video for the vet to check. The insulin appears fine with no clumps but it may have been left out for 30 mins or so and shaken a bit too roughly, would this cause it to become denatured or is this unlikely given that there are no clumps? The vet seems to think it is unlikely however we did get the new vial in Jan. We are going to change the insulin once we have ruled out with the vet that the issue is definitely not how we are administering it. Since he has concurrent diseases that can exacerbate diabetes, I believe it is more likely insulin resistance. Sorry for the essay. We are lost, as is the vet, as to why he was responding first and now he's not. Has anyone else had this experience? I would be grateful to hear back, thanks
