Mackenzie is 3 1/2 year old blond kitty. He was diagnosed in Jan 2016 with diabetes. Mackie has been in and out of our emergency/medical clinics in NM over the last 4 months with Insulin resistant diabetes with ketoacidosis as a complication. He is now on Levimir 20 units 2 X dailey plus 5 u of humulin R. Our internal med vets have been working on getting him stabilized but it hasn't happened so far. This is his 3rd insulin. I am not concerned with diabetes as much as the fact that randomly his BG will drop and he gets ketoacidosis almost immediately and ends up in the hospital on IV's. Has anyone out there had this kind of problem?
