Yes, you are correct, the insulin is Prozinc. I am only giving him this food (Purina DM) because it was recommended since he wasn't on insulen, just taken oral medicine Glipizide which doesn't seem to be working. I use to feed him Fancy Feast, regular Purina, Beyond wet food since I thought that was the best route to go to bring down his high sugar levels, but this didn't work. I think when I get him regulated on insulin, perhaps I can switch back. Not sure yet. The vet said I didn't have to test with his blood yet because I think she didn't want to overwhelm me. I feel, as I get use to giving him the injections, I will start to test using his blood. Wendell keytone levels are normal.
Thank you are helping me, I will admit I am a bit frightened about starting the injections, but truthfully, I watched videos on how to and it doesn't look hard so I think once I actually start, everything else will fall into place.
