I personally would never disparage vets. Like the rest of us they can differ in personality, conscientiousness and "people skills". Most do the absolute best they can do but are often limited in their experience with diabetic cats and as a result can have different views around feeding, dosing and monitoring than we have here. Some of those views, if followed, can lead a kitty into dangerous territory (no testing, doses that are too high or increases in whole unit increments, for example). It's a struggle for almost everyone who comes to FDMB to deviate from a trusted vet's advice. I was certainly one of those people. I spent 8 months at the beginning following my excellent vet's advice but got nowhere with Teasel and had no comprehension of why he was so very difficult to figure out. When I finally bit the bullet and came here, the magic combination of regular testing, keeping the spreadsheet and getting advice from experienced members opened the door wide for me. I'm very lucky in that my vet is willing to learn from me about managing diabetes in a complicated kitty. The rest, as they say, is history ...
