So a few days ago I took my cat, Bijou, to the vet due to a small dry cough she's been having for a while. The vet said she seemed healthy but had a small fever prescribed a hairball lubricant and also antibiotics of some sort that are not approved by the FDA. My bf and i looked at the reviews and side affects and they are actually pretty extreme for just an antibiotic. Side effects included seizures, bloody urine, involuntary eye movement, death, lethargy, loss of appetite (anorexia) Neurological disorders, Liver failure (hepatoxicity) Drop in white blood cell count (neutropenia) ect....Any idea why he would prescribe something so dangerous and not approved by the FDA for just a small fever? this is the website i looked at reviews and side effects on http://www.vetinfo.com/side-effects-metronidazole.html
