He was not responding to the Vetsulin. Andy has been the impossible child. Since we got him, we have not been able to get him regulated. He was on 6 units Lantus (no underlying diseases) when we adopted him and he almost hypoed a few times. So we switched him to PZI but that did not help. Another vet suggested going back to Lantus and I used this board to help - we started over at 1 u and he was much, much better. He had been on 1 to 1.5u maybe for the last year but still was bouncing a lot. This past month we noticed more "turbulence" and then the UTI which probably was result of it. In ER on Friday, they used Vetsulin and sent us home to try it. It seemed good but he wasn't eating other than me syringe-feeding. When he started to eat, it was not lowering his bg's enough so they decided to try Novolin and he responded well to that. Sorry for so much info but Andy has "history" and it is hard to keep it simple as this is over yrs. I will see where we are tomorrow and I assume start over again.
