Amy,
I'm so very sorry after all this wait that your vet visit was disappointing, to say the least. You do need to find a vet, though, for any issues that arise which would require a vet and for the RX for your insulin. I see that you're in FL, but I don't know where. If you post your city/town, there may be a mbr who lives near you and has a vet recommendation. In the meantime, I would call some vets and see if you can find out from the vet or vet tech or whoever about the vet's approach to treating FD.
******BEFORE you put your city or town, though, I think it's a good idea to take the name of the place where you work out of your profile info. This is a public message board and anyone can read it besides those of us who are here to help kitties.
Start a thread asking for vets in or near your city in the subject line. Then, we can see if we have some folks near you, who can help you out.
The sooner you can put some info in your signature of the profile, the better. Include your insulin, the DX date, food your feeding and that ketones were present. Also whether you are hometesting yet, so folks will have that and stop asking you the same thing over and over.
So sorry this vet was not a good one for you and scooby.
