My Jinx was recently diagnosed and has been on Novolin-n since 10/7. He was getting 3 units every 12 hours. I have been feeding him 2 cans of fancy feast classic chicken at 8am and 8pm when I give the shot. We just saw the vet again today for a glucose check and it was 310 I believe. The vet insists I feed him the Purina DM food from the vets office. From what I've read on here I thought what I was feeding him was ok but I'm just so new to this. The vet has increased his insulin dose to 4 units every 12 hours. Jinx has been moody all week and even peed on the floor once. I'm just trying to do what's best for Jinx and I'm feeling really overwhelmed by it right now. We go back on Saturday again for another glucose check. Jinx did gain one pound since last Saturday, which the vet said he should so I thought we were on the right track but his sugars are still so high.
