I took my girl to the vet a few days ago (for urinating where she shouldn't) and the doc prescribed antibiotics for a possible UTI and a mood elevator for her anxiety. She has to take the antibiotic for 14 days and the bottle says/the doc mentioned that she has to be confined for 7 days? Does anyone know why that could be? She's really not doing well with it and I can't figure out why she has to be confined. Thanks!
