I went to the vet today and spoke with the diabetic specialist. I told her about this message board and about Fancy Feast classics being lower in carbs than the Royal Canin Jake had been eating. I showed her my personal chart I'm keeping on my iPad, and that Jake has been able to go from 6u 2x to 2u 2x by taking him off dry. She was very impressed, and is going to check out what the board has to say, and show my vet the message board. Woo hoo! They are such good people there!
