Hi Amy! When dB was still around, I took him to Suman Prabhakar in Van Nuys. It's kind of a trek, but he and I learned FD together, and I showed him what I learned here as far as testing, etc. At the time I lived in the NH/Burbank area, but since have moved to Mt. Washington, so it's just too far for me. That said, now I take both my cats (epileptic, fiv+) to Studio City Animal Hospital (still far but a little closer!). There are several vets there, and they seem receptive to my questions about treatments, although I have never asked them about FD or home-testing (since I'm not dealing with a diabetic on a daily basis anymore). I have a friend who took his cats to the cats-only vet in Glendale, you might want to check them out. Of course Animal Specialty Group is amazing, but only by referral and only for specialists, and very expensive. Good luck! Nothing better than a good vet you can trust.
Purrs,
Karen & dB in spirit
