I just emailed back asking about what to feed in the mean time, explaining that she doesn't tolerate a lot of starch and her diarrhea is unlikely to clear up when she's eating a lot of starch - the answer was that I should give her rice+lean meat (this isn't my usual vet) and that she "doesn't recommend raw - but that's another subject".
I'm going to cook a mix of summer/winter squash since she seems to tolerate that well and use that as the carb. Hopefully that doesn't back fire on me.
And this is what she wants me to feed her:
Water sufficient for processing, pork by-products, rice flour, corn grits, corn meal, powdered cellulose, dried beet pulp, calcium carbonate, guar gum, natural flavors, gelatin by-products, carrageenan, potassium citrate, sodium tripolyphosphate, sodum silico aluminate, taurine, hydrolyzed yeasts, fish oil, vegetable oil, vitamins (DL-alpha-tocopherol acetate [source of vitamin E], L-ascorbyl-2-polyphosphate [source of vitamin C], biotin, thiamine mononitrate [vitamin B 1], niacin supplement, D-calcium pantothenate, riboflavin supplement [vitamin B2], pyridoxine hydrochloride [vitamin B6], vitamin B12 supplement, folic acid, vitamin D3 supplement), trace minerals (zinc oxide, ferrous sulfate, zinc proteinate, copper sulfate, manganous oxide, sodium selenite, calcium iodate), marigold extract (Tagetes erecta L.). - See more at: http://www.royalcanin.ca/index.php/Vete ... rtTav.dpuf

I can't even COUNT the number of things in that that would make her explode.
