Ok. 3.25 it was. Thanks for the advice---it was a tough decision for me. She is repeating a 48 hour cycle.
She still has liquid poo. She had one normal poo yesterday morning, followed by liquid poo just an hour later, and several more during the day.
The vet wants me to stop raw food and supplements until she gets over the diarrhea, or at least until we finish the 7 days of metronidazole.
I'm not happy she is back on high phosphorus FF, and off SEB. I also stopped her S. Boulardii and Animal Essentials supplements.
I might microwave her radcat raw chicken tonight, but she might not eat it.
Her urine, which looked clean when it was pulled Thursday, is still out for culture.
I want to board her at the vet again over Christmas, even though that didn't go very well at Thanksgiving.
