Hey! I have to disagree. W/resp. infections too low of humidity exacerbates the problem....raise the temps AND the humidity...80% or so. Too dry will compromise their breathing further adding stress on an already compromised respiratory system. Baytril works well..I had a young male w/a similar issue..nose rub and cold....cranked the heat and humidity and a three day dose of Baytril stopped if quickly...I was on it fairly early as it was a new aquisition so I tend to observe them more at first.
