In thinking back as to why the vet told me that about homestesting, my thought is that she didn't agree with it not because of its obvious advantages, but I think that she's dealt with too many owners who have tried it as well and botched it up because her response was, "You're tearing up his ear? Awww..." My other thought is that with so many monitors being on the market, it's hard to know which is a good one to buy that will give an accurate score, as well as pet owners not realizing that BG can fluctuate throughout the day & creating false alarms when seeing a low score. From judging my vet's reaction, I think that she's just dealt with too many uninformed clients...my other vet hasn't told me not to hometest and he listens when I tell him what BG scores I get. Both vets do listen, but I really give the first vet the benefit of the doubt because she's currently dealing with 6 different cases of feline diabetes, and only my cat responded to the insulin -- to the point of going the opposite direction. As for the other 5, I'm sure that she's beside herself trying to help her other clients.
