My cat was diagnosed in early sept. His glucose level was 568. Started with 1 unit novolin n. Blood level went up to 605. Insulin upped to 2 units. Level went down to 358. His insulin was upped to 3 units. His appetite got really bad. Wouldn't eat much of anything. Tried to give him canned food but he wouldn't eat it. Blood sugar went down to 220 but lost 2 lbs. brought his insulin down to 2 units. Started eating dry food really well so went up to 3 units. Blood sugar went back up to 538. Now he is getting 4 units but his appetite is starting to wan again. Wouldn't eat much tonight so he only got 2 units as per vet. So frustrated because any progress soon turns into a negative. In Sept he weighted 12 lbs. he is now down to 9 lbs 4 ozs. Pulling my hair out
