We're home. Basically, one of two thoughts. Feval sent out to check for anything, suspecting giardia. Otherwise, its completely possible she just caught some bug and just needs a little help to stop the shits.
We have a weeks worth of Metronidazole (if it is giardia, hopefully its a strain that the Metronidazole will take care of) and 10 days of FortiFlora. If it's not better in a week, we start thinking more serious and do further testing.
