Why was your cat placed on baytril versus another medication? Was there a culture that indicated baytril? No other alternatives?

Baytril has some problems with cats and especially a 17 year old cat. Here are the concerns.

1)"Higher doses (>5 mg/kg/day) not recommended in cats; may cause blindness" -Plumb's Veterinary Drug Handbook Fifth edition. What is the dosage on baytril for cats? 5mg/kg/day. This is difficult to dose and be right at the dose. Do not want to go too low and be ineffective or too high and run into the aforementioned risk. The North American Companion Animal Formulary gives the same description and dosage. Usually doses are given in ranges like baytril is given with dogs as 5-20mg/kg/day (Plumb).

2) "Caution: hepatic or renal insufficiency, dehydration" -Plumb's Veterinary Drug Handbook Fifth edition. Now how likely is it that 17 year old cat kidneys are not working at their full 100%? Renal (kidney) insufficiency is very common in older cats and almost assumed until proven otherwise in a 17 year old cat.

Just my concern upon reading your post and obviously not knowing the whole story.
