My cat Max is 11 years old with IBD and diabetes. He weighs 17 pounds. He was diagnosed on 6/24/21 with diabetes and we’ve been unable to get his glucose regulated. He was started on Prozinc 3 units twice a day and the vet had increased him weekly until we got to 6 units twice a day without much improvement. He runs mostly in the 400s, but has been over 600. He has IBD which complicates things with his diet due to his diarrhea. He eats Fancy feast or Purina pro plan Metabolic canned chicken mostly. No dry. He was in the hospital last week due to his sugar being over 600 and he stopped eating, plus had diarrhea. Dehydrated/questionable DKA. The vet changed him to Vetsulin 5 units twice a day. I know this insulin does not last more than 8 hrs in a cat although it has brought him down into the 250-300’s range for the most part. It just shoots back up to the 400-600 range when the insulin wears off. I give it at 6 am and 6 pm. I feed him one can of Purina pro plan or one can Fancy Feast in the morning and the evening. He stays hungry all the time but since he’s so hard to regulate I don’t know if he should be eating more, but if he does I can’t get his glucose level down. I free really wish this insulin would last longer or we could find something to regulate him more. I do have a spreadsheet on him of that would be helpful. Any recommendations about getting Max’s glucose under control?
