Becky...I know it's hard to trust a bunch of crazy internet cat ladies, especially when your vet is telling you something different, but please listen to the crazy cat ladies in this instance
When there's a DKA in the picture, it's vital that Ruckus get insulin....maybe not 3u but he must have some.....even if that means feeding a higher carb food to keep him safe
Vets only get 5 hours of "formal" education on diabetes when they're in school....and that covers all species of animal, not just cats....unless your vet just happens to have a special interest in feline diabetes, they probably don't get much in the way of continuing education on the latest treatments. The people here do nothing but deal with FD and the complications that come with it....and you'll see people here who've had many years of real life experience with treating their sugarcat
The people here are so dedicated to helping others that many of them remain on the message board even after their own cats have "Gone Ahead"....If you see GA next to a name here, that doesn't mean they're from Georgia...it means their kitties are waiting for them at the Rainbow Bridge, but they are still here, trying to help another
I've posted in the ProZinc forum and hopefully some of the people using your insulin will come along to help guide you, but I can assure you, it IS important that Ruckus get insulin
Sending lots of virtual hugs for you and your extra sweet Ruckus
