Winkie Winkler is a 15 year old 17 lb. Male Maine Coon. Diagnosed July 2003. Very difficult to regulate, unregulated on N, Glipizide, PZI-Vet, Lantus, and U. Started on imported Levemir August 11, 2005. Winkie has been prone to rebound even when a dip stays well above the critical zone. With other insulins, Winkie's rebounds would last for days. With Levemir they have lasted only hours. Treatment includes a specific diet of canned foods chosen from Binky's Page, (2-3 carbs/3 oz. with high fat) divided 6 times throughout the day.
