my 3yr old male BP has recently started to what sounds like, sneeze. i only hear it while im holding him, and only about once or twice a day. recently its increased in freqency slightly but not by much. the temps in the tank are a little warmer than usual (very hot here in the summer) and the humidity stays between 45-65%. regular aspen bedding that was just changed 2 weeks ago. tank recently dusted as well. any thoughts? was under the impression that resp infections occured when it was too cold. if anything its too warm right now. theres no disharge around nostrils, and mouth is clear. just a tiny sneeze or gasp now and then. no open mouth breathing or stareing upward
