I know how frustrated you and Calloway are over the insulin. Sorry that things haven't straightened out sooner.

Some animals are fairly easy to get under control others are more difficult. It's probably not helping that you have two vets with dissagreeing opinons either.

From what I see at work the ones that seem to have steadier insulin levels were caught early and have a very strict routine for feeding times, amounts and excercise. Not sure if it's as applicable to cats, since we see way more dogs with diabetes than cats, but I'd imagine the principle would be the same.

Is there just one vet of the two that you trust more? Maybe just request to only see that one, that way you don't get conflicting information?

I hope things straighten out soon for both you guys.
