I adopted my 2 year old cat, CJ, last July, and he had a runny nose. The vet put him on Baytril for 2 weeks, it went away, then came back a month later. The vet then put CJ and my other cat, Ava (who I have had 4 years) on Baytril for another 2 weeks. Neither had chest congestion, just stuffy noses, CJ with a thick, white discharge. They were both fine after the antibotics, then it came back in Jan. or so. The vet gave me 2 more weeks of Baytril. Same scenario AGAIN, it was back in March! By this point, a 6month old kitten, Oliver, adopted me. Back to the vet with all three, and all three went on Baytril for 30 days. Great results, but after a 2 months or so off Baytril, CJ's nose is stuffy again. Does anyone have any idea on what I need to do? The other two are fine at this point. None have ever lost appetite, but CJ and Ava do play a little bit less when their nose is stuff.
