Okay...JUH-EEEZ!!!! My heart goes out to you. There are a lot of issues here.
Partially, I'm just bumping this for you. Partially, I have a few measly things to say, but not much. I do feed raw and think it's tremendous. I had terrible digestive issues with Marcel - and spent hundreds early on at the vet - without any real resolution. FINALLY, I found a nutritionist (holistic, but classically trained) who works at a vet practice in Calif. and consults via phone internationally - out of desperation, I thought, what the heck.
Well, she changed everything for Marcel. Many vets, nationally, do nutritional consults w/ her for their cancer pet patients. She does use raw for her liver patients - I don't know how - but I know that she does bc she once mentioned this in passing as she is a big believer in raw (but in variety as well). Personally, I think she is *wonderful* - and I can't say enough about her.
Marcel recommends her even more highly (my avatar). You can check her out at -
www.askariel.com. I can't answer your more complicated stuff - but I know that she, perhaps in concert w/ YOUR vet as well as HER staff vet, could get you really well situated. Just my 2 cents.
Please keep me posted, if you can!
