Hey Sarah, I totally get the frustration there and sorry you’re dealing with that

. I think that’s why a lot of us just stopped engaging with our vets regarding the details of FD management. It’s not their fault, this is a complicated disease and they have so much else to handle and know as a veterinarian…
I wouldn’t write back anymore, personally. And if they gave me a problem about that decision I’d find a new vet (I’ve done this, but understand there are challenges sometimes). But if I were to respond, I would emphasize that yes, none of us here are vets, but, a human doctor put together the information here all based on actual FD research papers and published guidelines. With hundreds if not thousands of cats achieving remission…
The advice they gave might work, but is risky and doesn’t line up with what’s been going on on this forum for 30 years.
So all that to say, I’m not trying to put down your vet. I’m sure they’re great at a lot of things and we need our vets. Just not necessarily for every FD intricacy IMO.
