My inexpert opinion is she's having some upset due to 2 weeks on antibiotics. The issue with probitoics and antibiotics is that the antibiotics will kill ALL bacteria, even the good ones, so the probiotics need to be given at a different time than the antibiotics, that's all. While Mazy cat was on clavamox (after her extractions about the same time as Lola, but only a week) I just made sure her probiotics were given more a number of hours before or after the antibiotic.
Her internal flora is just all messed up now. I'd get her back on the probiotic, feed milder meats, just chicken breast even, for a few days, maybe even go boneless for a couple of days, and see how she does.
