My cat Pumpkin was diagnosed with diabetes May 31st. He was started on Lantus. Didn't seem to be working. Switched to Vetsulin. This also didn't seem to be working (on Hill's w/d during this time). My vet was stumped. I got on the computer and found Dr. Pierson of CatInfo.org. Got Pumpkin off the w/d and put him on Fancy Feast classics and back on Lantus. The lowest number I've gotten on him was 386 with 5 units. We are starting 6 units tonight. Pumpkin has the unkept look to his fur. He still wants to go outside and sit on the back porch and he visits a little next door. He doesn't have ketones in his urine.But he just doesn't seem right. I'm worried. I'm worried I'm going to lose him. Every time the number goes down, it crawls back up. the curve doesn't show Smoeygi. Just can't seem to keep the number down. Not sure if I'm panicking and not giving insulin enough time or is Lantus not working for him. Has anyone else had this issue.
